Impact of the type of fuel burned and the heating device on the quality of atmospheric air

Abstract

The article analyzes the impact of fuel type and heating device on the quality of atmospheric air in an area including 15 emitters characteristic for single-family households. The air quality analysis was conducted by calculating the concentrations of dust and gas pollutants in the atmosphere at various distances from the emitters. Dust and gas pollutants emitted as a result of heating single-family houses and heating utility water were taken into account: suspended dust PM10, sulfur dioxide, nitrogen dioxide and carbon dioxide. Eight variants of the device were used, fired with gaseous, solid and liquid fuels, in older and modern versions. The Ek100w program from Atmoterm was used to calculate the immission of pollutants. Calculations have shown that the maximum SO2 immission is 963 times lower in the case of natural gas combustion in modern boilers than when firing with “eco-pea coal”, the maximum NO2 immunity caused by the use of modern heating devices is lower in the case of natural gas combustion in modern boilers than with “eco-pea coal” almost 5 times, while the maximum emission of PM10 dust is about 1283-fold lower in the case of natural gas combustion in modern boilers than when using “eco-pea” coal.
