Analysis of emissions during the combustion of pellets in boiler units

The object of research is the technological process burning pellets in boilers. Using solid fuel boilers on for heat production, they are trying to reduce dependence hydrocarbon energy resources. Often such installed autonomous heating schools and other communal facilities. One most problematic areas analysis environmental impact when using as a municipal boiler houses urban areas. Boilers operating fuels characterized by larger range pollutants, well large values concentrations emitted through chimney. In course research, instrumental measurement tools were used, which made it possible obtain value pollutants emissions from chimneys particular, average maximum main were: nitrogen dioxide – 271.78 mg/m3, carbon 1935.44 sulfur dioxin 13.37 suspended solids, undifferentiated composition (dust, ash) 93.2 mg/m3. data measurements according method calculating harmful substances atmospheric air, map dispersion was created. Surface concentration fields plotted scatter map, makes compare obtained with hygienic normative air. This determine distance where highest emission source recorded. By combining methods calculation methods, volumes nomenclature determined. amount per unit mass burned boiler. conducted studies theoretical calculations various types production heat, this will allow assessing their air pollution reducing risk harm human health.
