Co-combustion of coal and solid municipal waste is a social phenomenon. It constitutes an important emission source of harmful air pollutants. The comparative research was conducted. It concerned co-combustion of coal and different types of municipal solid waste (including wastepaper, PE, PVC) in the domestic CH (central heating) boiler (18-kW power) equipped with an automatic fuel feeder. The aim of this research was to compare the parameters of flue gas, content of dust (fly ash) and gaseous air pollutants in the flue gases from the CH boiler. During the combustion were taken the fly ash samples and was continuously analyzed qualitative and quantitative composition of flue gas. Chemical analysis of flue gases included: CO2, CO, H2O, SO2 and NOx. Concentration of fly ash in the flue gas was determined. The fly ash samples were analysed for the organic, elemental and total carbon, PM10 and PM2,5, and 16 PAHs content. The results were analyzed in terms of combustion efficiency, emissions of major pollutants (NOx, CO, SO2) and fly ash with adsorbed of PAHs on its surface. The average concentration of emitted particulate matter was 764 mg m-3, and CO – 1944, SO2 – 1256 NOx – 555 mg m -3 (STP, 3% O2, dry gas). The flue gases contain fly ash, with a significant carbon content EC (average 31%) and a high proportion of PM10 and PM2.5 – respectively 100 and 75% by volume.
