The combustion was performed in a 50 kW boiler type Biowarmer with a cast-iron moving step grate. The temperature in the combustion chamber did not exceed 800 ◦C. For all biomass types, only brittle slag was generated in the furnace, which was easily broken by a reciprocating movement of the grate. Carbon monoxide concentration in the flue gas except for the case of sewage sludge pellet firing did not exceed the permitted value of 3000 mg/m3 and nitric oxide concentration 515 mg/m3, both presented for 10% O2 concentration in the flue gas based in dry gas. Hydrocarbon concentrations for all test runs were close to zero.}, type={Artykuły / Articles}, title={Gaseous emissions during agricultural biomass combustion in a 50 KW moving step grate boiler}, URL={http://www.journals.pan.pl/Content/103648/PDF/5_Palaszynska_CPE-39(2)-2018.pdf}, keywords={agricultural biomass, boiler, pollutant emission, combustion}, }
