| Popis: | Sewage sludge incineration in a fluidized bed is considered to be one of the most suitable ways of sewage sludge disposal. This process reduces the volume of the waste and causes the destruction of organic contaminants such as POPs, pharmaceuticals and other compounds with endocrine-disrupting potential. Oxygen-enriched air combustion and oxy-fuel combustion can increase the combustion efficiency, reduce the amount of flue gas and make possible CO2 capture more effective. However, the influence of incineration medium composition has not yet been thoroughly investigated in case of sewage sludge incineration. In this paper, the incineration of sewage sludge in a bubbling fluidized bed reactor was studied at oxygen-enriched air conditions, oxy-fuel conditions and oxy-fuel conditions with zero and non-zero concentrations of steam, CO, NO, N2O and SO2 in the inlet combustion medium. Consequently, the effects of various operating parameters on pollutants formation were comprehensively described with emphasis on... |
