conducting an inventory of emissions of pollutants into the atmosphere for asphalt concrete plants

(by calculation method)

The preparation of the 2nd revised and supplemented edition of this Methodology was attended by: Ph.D. Donchenko V. V., Ph.D. Manusadzhyants Zh. G., Samoilova L. G., Solntseva G. Ya. (NIIAT), Ph.D. n. Mazepova V. I., Bobkov V. V., Berezhnaya Yu. A. (NPO RosdorNII).

INTRODUCTION

This methodology was developed by order of the Ministry of Transport Russian Federation and is designed to provide methodological assistance to employees of operating asphalt concrete plants (APC) in conducting an inventory of pollutant emissions, developing draft standards for maximum permissible emissions (MAE), environmental passports, determining the level of impact of individual emission sources on the state of the air, forecasting the magnitude of emissions in the future.

1. GENERAL PROVISIONS

The methodology establishes the procedure for calculating emissions of pollutants from technological equipment installed on the territory of the asphalt plant. As a rule, in addition to the main technological equipment for the preparation of asphalt concrete and the preparation of mineral and binder materials, numerous sites are located on the territory of the asphalt plant, the products of which are used in the construction and repair work in the road industry. The main purpose of the inventory of pollutants is to obtain initial data for: environment(atmospheric air); - development of draft standards for emissions of pollutants into the atmosphere both from the asphalt plant as a whole and for individual sources of air pollution; - organization of control over compliance with established standards for emissions of pollutants into the atmosphere; - assessment of the environmental characteristics of technologies used at the asphalt plant; - planning of air protection works at the asphalt plant. The calculation of gross and maximum single emissions of pollutants is carried out using specific indicators, i.e. the amount of emitted pollutants, reduced to units of time, equipment. mass of consumable materials. Specific indicators of pollutant emissions from production sites are given on the basis of the results of studies and observations carried out by various research and design institutes. The work on the calculation of pollutant emissions is carried out by the asphalt plant either on its own or attracts a specialized organization for this. licensed to carry out such work. If calculations of pollutant emissions are carried out by a specialized organization, then it must require the asphalt plant to provide data on the actual quantity and type of equipment, the quantity and grades of materials used, the number of days of operation per year for each piece of equipment and its net operating time per day. ABS is responsible for the completeness and reliability of the inventory data. Calculation of emissions from asphalt plants should be carried out on the basis of the actual technical characteristics of this mixer. In the Methodology, for reference, specifications for asphalt concrete plants, released earlier and constituting the main fleet in road organizations.

2. SOURCES OF POLLUTANT EMISSIONS AT ASPHALT CONCRETE PLANTS

The industrial site of the asphalt plant, as a rule, includes workshops for the preparation of organic binder and asphalt concrete, the preparation of mineral materials, and boiler houses. Often, shops for the preparation of road viscous bitumen from raw materials (tar), bitumen emulsions, reinforced soils, stone crushing and screening plants are also located here. ABZ can be equipped with sets of equipment of the following types: D-597. D-597A, D-508-2A, D-617. D-645-2. DS-117-2K (2E), DS-1895, D-158, "Teltomat" made in Germany and other imported asphalt mixing plants/capacity 25, 32-42, 50, 100 and 200 t/h. Sources of air pollution are divided into sources of emission and sources of emissions of pollutants into the atmosphere. Sources of pollutant emission are: technological unit, installation, device, apparatus, etc., emitting pollutants during operation. Sources of pollutant emissions are: a pipe, an aeration lamp, a bunker, a ventilation shaft, a manhole, etc. devices that release pollutants into the atmosphere. Emissions of pollutants are divided into organized and unorganized. Organized emissions are emissions diverted from the places of emission by a system of gas outlets, which makes it possible to use appropriate installations to capture them. Unorganized emissions are emissions that occur due to leaks in process equipment, gas outlets, tanks, open places of dusting and evaporation, etc. An inventory should be carried out for both organized and fugitive emissions. Sources of emission and release of pollutants at the asphalt plant are given in Table. 2.1. During the operation of the asphalt plant, the following pollutants are released into the atmosphere: inorganic dust, with different content of silicon dioxide; oxides of carbon and nitrogen; sulfurous anhydride (sulfur dioxide); hydrocarbons, in particular polycyclic ones: fuel oil ash (in terms of vanadium) when using fuel oil as a fuel; soot during the operation of transport on diesel fuel; lead and its inorganic compounds during the operation of vehicles on leaded gasoline. The classification of these emissions is given in Table. 2.2. In table. 2.3 shows the characteristics of emissions from sources of pollutant emission at the asphalt plant. Equipment that emits pollutants is equipped with dust and gas cleaning systems, which include: dust collectors of various types with gas ducts and smoke exhausters; devices that provide the required temperature conditions; hopper with mechanical means for supplying dust to the dispensers of the mineral powder unit. The equipment used for the deposition of dust from dusty gas can be divided into five main groups: dust collectors, cyclones, wet dust collectors, fabric filters and electrostatic precipitators. When storing tar, processing it into bitumen, heating bitumen and preparing asphalt concrete, hydrocarbons are released. The source of pollutant emissions at the asphalt plant are reactor plants for the preparation of bitumen from oil tar by oxidizing the latter with atmospheric oxygen. According to the principle of operation, reactor installations can be of a non-compressor type (T-309) - in them, atmospheric air is injected and sprayed into the oxidized raw material as a result of the rotation of the dispersers; or bubbling, in which air is supplied by a compressor (type SI-204). In reactor plants, during the oxidation of tar, 5-140 kg of oxidation gases are released per 1 ton of finished bitumen, depending on its brand, as well as on the quality of the feedstock. Oxidation gases contain about 5% hydrocarbons. The oxidation gases exit the reactor into a manifold connected to a hydrocyclone. Steam and the bulk of hydrocarbons condense in it, forming water and a "black solarium". Some of the hydrocarbons - about 20% of their initial amount - are fed together with other components of the oxidation gases into a special afterburner, which is part of the reactor plant complex. In the event that the reactor plant is not provided with an afterburner, the specific emission of a pollutant (hydrocarbons) can be taken as an average of 1 kg per 1 ton of finished bitumen.

3.9. Calculation of gross emissions of pollutants at reactor plants for the preparation of bitumen and in emulsion shops

During the operation of reactor plants, the following are emitted into the atmosphere: hydrocarbons, fuel oil ash (in terms of vanadium), oxides of sulfur, carbon and nitrogen, as well as solid particles. The calculation of gross emissions of these substances is carried out in accordance with paragraphs. 3.2 - 3.6 of this methodology. When bitumen emulsions are produced in emulsion shops, bitumen can be supplied to the disperser in a heated form through a pipeline from the ABZ bitumen melting plant, or it can be heated in boilers on the territory of the emulsion shop. In the first case, only gross hydrocarbon emissions are calculated in accordance with clause 3.7 of this methodology, in the second case, gross emissions of hydrocarbons, fuel oil ash (in terms of vanadium), sulfur oxides, carbon and nitrogen oxides, as well as particulate matter are calculated.

3.10. Calculation of gross emissions of pollutants in shops for the preparation of reinforced soils

Reinforced soils in the workshops located on the territory of the asphalt plant are prepared on stationary or semi-stationary type plants (most often of the DS-50 type). Mixtures are prepared using mineral (cement, lime, fly ash), organic (bitumen, tar, tar) or complex binders (mineral and organic). During the operation of the installations, dust is emitted into the atmosphere (at the places of loading and dosing of mineral materials), as well as hydrocarbons (when organic or complex binders are used) in the area of ​​preparation of organic binders. Most often, at these installations, organic binders are heated using electricity (electric heaters). To calculate dust emissions, the formulas given in paragraph 3.1 are used, and hydrocarbons in accordance with paragraph 3.7 of this methodology. When using fuel oil for heating organic binders, it is also necessary to take into account emissions of fuel oil ash (in terms of vanadium), sulfur oxides, carbon and nitrogen, as well as particulate matter (paragraphs 3.2 - 3.6).

3.11. Calculation of emissions of pollutants from fuel combustion in boiler units of a boiler house

Boiler units of boiler houses operate on various types of fuel (solid, liquid and gaseous), so emissions of pollutants from their combustion will be different. The pollutants considered include: nitrogen dioxide, carbon monoxide, sulfur dioxide, particulate matter, and in the case of fuel oil combustion - fuel oil ash (in terms of vanadium). Calculation of emissions of the above pollutants from fuel combustion in own boiler houses is carried out in accordance with the current methodology. When calculating the maximum single emission, the fuel consumption for the coldest month of the year (t, thousand m 3) is taken.

3.12. Calculation of emissions of pollutants from mobile sources

On the territory of the asphalt plant, mobile sources include vehicles that carry out intra-factory technological transportation. The calculation of gross and maximum one-time emissions from these vehicles is carried out in accordance with the current methodology, while the coefficient of release of cars on the line and the passing time is taken equal to 1. If there is a quarry at the asphalt plant, then the gross and maximum one-time emissions from cars are determined by the method.

3.13. Calculation of gross emissions of pollutants in quarries

When developing quarries, it is necessary to take into account emissions of pollutants during excavation, loading and drilling operations. 3.13.1. Emissions during excavation and loading operations The maximum one-time amount of dust released into the atmosphere when loading by an excavator into dump trucks is calculated by the formula:

, g/s (3.13.1)

Where P 1 - the content of silt and clay particles in the rock, in fractions of a unit. P 1 = 0.05; P 2 - coefficient taking into account the wind speed in the excavator operation area (Table 3.13.1 or submitted by the meteorological service); P * 3 - coefficient taking into account the moisture content of the material (Table 3.2, section 3.1); ___________ * For year-round operation of the quarry, take into account P z \u003d 0.01.

INVENTORY OF POLLUTANT EMISSIONS
INTO THE ATMOSPHERE FOR MOTOR TRANSPORT ENTERPRISES
(BY CALCULATION METHOD)

The methodology for conducting an inventory of emissions of pollutants into the atmosphere for motor transport enterprises was developed by order of the Ministry of Transport of the Russian Federation.

The methodology is designed to calculate gross and maximum one-time emissions from mobile and stationary sources located on the territory of a motor transport enterprise.

With the release of this Methodology for conducting an inventory of emissions of pollutants into the atmosphere for motor transport enterprises, the previously existing Methodology with the same name, approved in 1992, and an addition to it, approved in 1993, are cancelled.

The following persons took part in the revision of the Method: Donchenko V.V., Manusadzhyants Zh.G., Samoilova L.G., Kunin Yu.I., Solntseva G.Ya. (NIIAT), Ruzsky A.V., Kuznetsov Yu.M. (MADI).

1. GENERAL PROVISIONS

This methodology establishes the procedure for calculating gross and maximum one-time emissions of pollutants from sources of air pollution on the territory of motor transport enterprises, regardless of their departmental affiliation and ownership, as well as freight stations and terminals, garages and car parks, organizations providing maintenance and repair services cars.

The main purpose of the inventory of pollutant emissions is to obtain initial data for:

development of draft standards for maximum permissible emissions of pollutants into the atmosphere both from enterprises as a whole and for individual sources of air pollution;

organization of control over compliance with established standards for emissions of pollutants into the atmosphere;

assessment of the environmental characteristics of technologies used at the enterprise;

planning of air protection works at the enterprise.

The calculation of gross and maximum single emissions of pollutants is carried out using specific indicators, i.e. the amount of emitted pollutants, reduced to the units of equipment used, the time of operation of vehicles or equipment, the mileage of vehicles, the mass of consumable materials.

Specific indicators of pollutant emissions from production sites are given on the basis of the results of studies and observations carried out by various research and design institutes

2. CALCULATION OF POLLUTANT EMISSIONS FROM CAR PARKING

In this methodology, a car park is understood as an area or room intended for storing cars for a certain period of time. Cars can be placed:

In separate open parking lots or in separate buildings and structures (closed parking lots) with direct entry and exit to public roads (calculation scheme 1, Fig. 1);

In open parking lots or in buildings and structures that do not have direct entry and exit to public roads and are located within the boundaries of the object for which the calculation is performed (calculation scheme 2, Fig. 1).

Gross and maximum one-time emissions of pollutants under the selected design scheme 1 are determined only for the parking area or premises, and under scheme 2 they are determined for each parking lot and for each internal passage.

The calculation of pollutant emissions from multi-storey parking lots is set out in the calculation scheme 3.

The calculation of pollutant emissions is carried out for six pollutants: carbon monoxide - CO, hydrocarbons - CH, nitrogen oxides -NO x, in terms of nitrogen dioxide NO 2, particulate matter - C, sulfur compounds, in terms of sulfur dioxide SO 2 and compounds lead - Pb. For vehicles with gasoline engines, emissions of CO, CH, NO x ,SO 2 and Pb are calculated (Pb - only for regions where leaded gasoline is used); with gas engines - CO, CH, NO x, SO 2; with diesel engines - CO, CH, NO x, C, SO 2.

Calculation scheme 1.

Emissions of the i-th substance by one car of the k-th group per day when leaving the territory or parking space and returning are calculated by the formulas:

The following designations are used in the tables:

engine type: B - gasoline, D - diesel, G 1) - gas (compressed natural gas); when using liquefied petroleum gas, specific emissions of pollutants are equal to emissions when using gasoline, there is no Pb emission;

period of the year: T - warm, X - cold;

storage conditions

cars: BP - open or closed unheated parking lot without heating means; SP - open parking, equipped with heating facilities. For warm closed parking lots, specific emissions of pollutants in the cold and transitional periods of the year are taken equal to specific emissions in the warm period.

APPROVED by the Ministry of Transport of the Russian Federation on October 28, 1998

The preparation of the 2nd revised and supplemented edition of this Methodology was attended by: Ph.D. Donchenko V.V., Ph.D. Manusadzhyants Zh.G., Samoilova L.G., Solntseva G.Ya. (NIIAT), Ph.D. n. Mazepova V.I., Bobkov V.V., Berezhnaya Yu.A. (NPO RosdorNII).

INTRODUCTION

This methodology was developed by order of the Ministry of Transport of the Russian Federation and is designed to provide methodological assistance to employees of operating asphalt concrete plants (APP) in conducting an inventory of pollutant emissions, developing draft standards for maximum allowable emissions (MPE), environmental passports, determining the level of impact of individual emission sources on the air environment, predicting the magnitude of emissions for the future.

1. GENERAL PROVISIONS

The methodology establishes the procedure for calculating emissions of pollutants from technological equipment installed on the territory of the asphalt plant. As a rule, in addition to the main technological equipment for the preparation of asphalt concrete and the preparation of mineral and binder materials, there are numerous sites on the territory of the asphalt plant, the products of which are used in construction and repair work in the road industry.

The main purpose of the inventory of pollutants is to obtain initial data for:

• assessing the degree of impact of emissions of pollutants emitted by the asphalt plant on the environment (atmospheric air);
• development of draft standards for emissions of pollutants into the atmosphere, both from the asphalt plant as a whole and for individual sources of air pollution;
• organization of control over compliance with established standards for emissions of pollutants into the atmosphere;
• assessment of the environmental performance of technologies used at the asphalt plant;
• planning of air protection works at the asphalt plant.

The calculation of gross and maximum single emissions of pollutants is carried out using specific indicators, i.e. the amount of emitted pollutants, reduced to units of time, equipment, mass of consumable materials.

Specific indicators of pollutant emissions from production sites are given on the basis of the results of studies and observations carried out by various research and design institutes.

The work on the calculation of pollutant emissions is carried out by the ABZ either on its own, or for this purpose it attracts a specialized organization that has a license to carry out such work. If calculations of pollutant emissions are carried out by a specialized organization, then it must require the asphalt plant to provide data on the actual quantity and type of equipment, the quantity and grades of materials used, the number of days of operation per year for each piece of equipment and its net operating time per day. ABS is responsible for the completeness and reliability of the inventory data.

Calculation of emissions from asphalt plants should be carried out on the basis of the actual technical characteristics of this mixer. For reference, the Methodology provides technical characteristics for asphalt concrete plants that were produced earlier and make up the main fleet in road organizations.

2. SOURCES OF POLLUTANT EMISSIONS AT ASPHALT CONCRETE PLANTS

The industrial site of the asphalt plant, as a rule, includes workshops for the preparation of organic binder and asphalt concrete, the preparation of mineral materials, and boiler houses. Often, shops for the preparation of road viscous bitumen from raw materials (tar), bitumen emulsions, reinforced soils, stone crushing and screening plants are also located here.

ABZ can be equipped with sets of equipment of the following types: D-597, D-597A, D-508-2A, D-617, D-645-2, DS-117-2K (2E), DS-1895, D-158, "Teltomat" manufactured by Germany and other imported asphalt mixing plants with a capacity of 25, 32-42, 50, 100 and 200 t/h.

Sources of air pollution are divided into sources of emission and sources of emissions of pollutants into the atmosphere.

Sources of pollutant emission are: technological unit, installation, device, apparatus, etc., emitting pollutants during operation.

Sources of pollutant emissions are: a pipe, an aeration lamp, a bunker, a ventilation shaft, a manhole, etc. devices that release pollutants into the atmosphere.

Emissions of pollutants are divided into organized and unorganized.

Organized emissions are emissions diverted from the places of emission by a system of gas outlets, which makes it possible to use appropriate installations to capture them.

Unorganized emissions are emissions that occur due to leaks in process equipment, gas outlets, tanks, open places of dusting and evaporation, etc.

An inventory should be carried out for both organized and fugitive emissions.

The sources of emission and release of pollutants at the asphalt plant are given in Table 2.1.

During the operation of the asphalt plant, the following pollutants are released into the atmosphere: inorganic dust, with different content of silicon dioxide; oxides of carbon and nitrogen; sulfurous anhydride (sulfur dioxide); hydrocarbons, in particular polycyclic ones; when using fuel oil as a fuel; soot during the operation of transport on diesel fuel; lead and its inorganic compounds during the operation of vehicles on leaded gasoline.

The classification of these emissions is given in Table 2.2.

Equipment that emits pollutants is equipped with dust and gas cleaning systems, which include: dust collectors of various types with gas ducts and smoke exhausters; devices that provide the required temperature conditions; hopper with mechanical means for supplying dust to the dispensers of the mineral powder unit. The equipment used for the deposition of dust from dusty gas can be divided into five main groups: dust collectors, cyclones, wet dust collectors, fabric filters and electrostatic precipitators.

When storing tar, processing it into bitumen, heating bitumen and preparing asphalt concrete, hydrocarbons are released.

The source of pollutant emissions at the asphalt plant are reactor plants for the preparation of bitumen from oil tar by oxidizing the latter with atmospheric oxygen.

According to the principle of operation, reactor installations can be of a non-compressor type (T-309) - in them, atmospheric air is injected and sprayed into the oxidized raw material as a result of the rotation of the dispersers; or bubbling, in which air is supplied by a compressor (type SI-204).

In reactor plants, during the oxidation of tar, 5-140 kg of oxidation gases are released per 1 ton of finished bitumen, depending on its brand, as well as on the quality of the feedstock. Oxidation gases contain about 5% hydrocarbons.

The oxidation gases exit the reactor into a manifold connected to a hydrocyclone. Steam and the bulk of hydrocarbons condense in it, forming water and a "black solarium".

Some of the hydrocarbons - about 20% of their initial amount - are supplied, together with other components of the oxidation gases, to a special afterburner, which is part of the reactor plant complex.

In the event that the reactor plant is not provided with an afterburner, the specific emission of a pollutant (hydrocarbons) can be taken as an average of 1 kg per 1 ton of finished bitumen.

3.9. Calculation of gross emissions of pollutants at reactor plants for the preparation of bitumen and in emulsion shops

During the operation of reactor plants, the following are emitted into the atmosphere: hydrocarbons, fuel oil ash (in terms of vanadium), oxides of sulfur, carbon and nitrogen, as well as solid particles. The calculation of gross emissions of these substances is carried out in accordance with paragraphs 3.2-3.6 of this methodology.

When bitumen emulsions are produced in emulsion shops, bitumen can be supplied to the disperser in a heated form through a pipeline from the ABZ bitumen melting plant, or it can be heated in boilers on the territory of the emulsion shop. In the first case, only gross hydrocarbon emissions are calculated in accordance with clause 3.7 of this methodology, in the second case, gross emissions of hydrocarbons, fuel oil ash (in terms of vanadium), sulfur oxides, carbon and nitrogen oxides, as well as particulate matter are calculated.

3.10. Calculation of gross emissions of pollutants in shops for the preparation of reinforced soils

Reinforced soils in the workshops located on the territory of the asphalt plant are prepared on stationary or semi-stationary type plants (most often of the DS-50 type). Mixtures are prepared using mineral (cement, lime, fly ash), organic (bitumen, tar, tar) or complex binders (mineral and organic).

During the operation of the installations, dust is emitted into the atmosphere (at the places of loading and dosing of mineral materials), as well as hydrocarbons (when organic or complex binders are used) in the area of ​​preparation of organic binders. Most often, at these installations, the heating of organic binders is carried out using electricity (electric heaters).

To calculate dust emissions, the formulas given in clause 3.1 are used, and hydrocarbon emissions are used in accordance with clause 3.7 of this methodology. When using fuel oil for heating organic binders, it is also necessary to take into account emissions of fuel oil ash (in terms of vanadium), sulfur oxides, carbon and nitrogen, as well as particulate matter (clauses 3.2-3.6).

3.11. Calculation of emissions of pollutants from fuel combustion in boiler units of a boiler house

Boiler units of boiler houses operate on various types of fuel (solid, liquid and gaseous), so emissions of pollutants from their combustion will be different.

The pollutants considered include: nitrogen dioxide, carbon monoxide, sulfur dioxide, particulate matter, and in the case of fuel oil combustion - fuel oil ash (in terms of vanadium).

Calculation of emissions of the above pollutants from fuel combustion in own boiler houses is carried out in accordance with the current methodology.

When calculating the maximum single emission, the fuel consumption for the coldest month of the year (t, thousand m) is taken.

3.12. Calculation of emissions of pollutants from mobile sources

On the territory of the asphalt plant, mobile sources include vehicles that carry out intra-factory technological transportation.

The calculation of gross and maximum one-time emissions from these vehicles is carried out in accordance with the current methodology, while the coefficient of release of vehicles per line and the time of passing is taken equal to 1.

If there is a quarry at the asphalt plant, then the gross and maximum one-time emissions from cars are determined by the method.

3.13. Calculation of gross emissions of pollutants in quarries

When developing quarries, it is necessary to take into account the emissions of pollutants during excavation, loading and drilling operations.

3.13.1. Emissions during excavation and loading operations

The maximum one-time amount of dust released into the atmosphere when loading by an excavator into dump trucks is calculated by the formula:

G/s (3.13.1)

where - the content of silt and clay particles in the rock, in fractions of a unit, 0.05;

Coefficient taking into account the wind speed in the area of ​​the excavator (Table 3.13.1 or according to the weather service);

* - coefficient taking into account the moisture content of the material (Table 3.2, Section 3.1);

1. Basic provisions
The Guidelines establish the procedure for calculating emissions of pollutants from stationary sources of existing and planned railway transport enterprises and can be used in the development of project documentation for the protection of the air from pollution in cases where the use of field measurements is difficult or impractical.
The calculation of emissions is based on the use of specific indicators, i.e. emissions of pollutants, reduced to a unit of time, equipment, mass of products received or consumed fuel, raw materials and materials.
Specific indicators of pollutant emissions from production equipment were identified based on the results of research conducted by research and design organizations at railway transport enterprises, as well as on the basis of available data obtained from similar industries in other sectors of the national economy.
These guidelines may subsequently be supplemented in connection with the emergence of new technological equipment, the use of other types of raw materials, materials and technological processes, data on which are currently not available.

2. Calculation of pollutant emissions from fuel combustion

in the boiler units of the boiler house

2.1. General provisions
The proposed calculation is designed to determine the emission of pollutants into the atmosphere with gaseous combustion products during the combustion of solid fuels, fuel oil and gas in the furnaces of industrial and municipal boilers and heat generators (small heating boilers, heating and welding machines, furnaces) with a capacity of up to 30 t/h.
When burning solid fuels, along with the main combustion products (CO, HO, NO), the following enter the atmosphere: fly ash with particles of unburned fuel, oxides, sulfur, carbon and nitrogen. When burning fuel oil with flue gases, sulfur oxides, nitrogen dioxide, solid products of incomplete combustion and vanadium compounds are emitted. When burning gas with flue gases, the following are emitted: nitrogen dioxide, carbon monoxide.
When compiling this section, the following were used: "Guidelines for the calculation of pollutant emissions from fuel combustion in boiler houses with a capacity of up to 30 t/h". Moscow, Gidrometizdat, 1985

2.2. Calculation of pollutant emissions from fuel combustion

in the boiler units of the boiler house
Boiler units of boiler houses operate on various types of fuel (solid, liquid and gaseous). Emissions of pollutants depend both on the amount and type of fuel, and on the type of boiler.
The considered pollutants emitted during fuel combustion are: particulate matter, carbon monoxide, nitrogen oxides, sulfur dioxide (sulphur dioxide), vanadium pentoxide.
1. Gross emission of solid particles in flue gases of boiler houses is determined by the formula:
, t/year (2.2.1)
where: - ash content of the fuel, in% (Table 2.2.1);
- the amount of fuel consumed per year, t;
- dimensionless coefficient (Table 2.2.4);
- efficiency of ash collectors, % (Table 2.2.2.).
