Our paper brings information about investigation of the effects of combustion (fluidized bed) temperature and concentration of oxygen in inlet combustion media on the emissions of NOx, N2O and SO2 in FB incineration of sewage sludge at temperatures 750–930 °C. Concentrations of oxygen in the inlet gas during experiments were 21, 25, 28 and 30 vol. %. Experiments were carried out in a bubbling fluidized bed (BFB) reactor with inner diameter of 9.36 cm and height of 130 cm above the gas distributor. To simulate oxy-fuel BFB combustion, a mixture of oxygen and carbon dioxide as a gaseous combustion medium was used. Dry sewage sludge (SS) from mesophilic stabilization (moisture content 9 mass % and ash content 44 mass % in dry matter) was used for experiments.
