Influence of Operating Conditions and Coal Properties on NOx and N2O Emissions in Pressurized Fluidized Bed Combustion of Subbituminous Coals
Original language description
Our experimental study is aimed at finding effects of operating conditions in Pressurized Fluidized Bed Combustion (PFBC) of subbituminous coals differing in ash content/composition and in particle size distribution on nitrogen oxide ( NOx + N2O) emissions. The experiments have been performed on a smaller laboratory apparatus with ID = 8 cm. The effects of operating pressure (0.1 - 1 MPa), temperature of the fluidized bed ( 800 - 900 oC), freeboard temperature and oxygen concentration (3 - 10 vil. %) influe gas on the nitrogen oxides emissions is relatively complex, coupled with temperature of burning coal particles. The NOx emissions decrease with increasing pressure, the N2O emissions can exhibite a maximum at pressure 0.2 - 0.5 MPa or can be practically constant. At higher temperatures (900 oC) the N2O emissions are small/negligible.

Vliv pracovních podmínek a vlastností uhlí na emise NOx a N2O ze spalování subbitumenózních uhlí v tlakové fluidní vrstvě
Czech description
Experimenty byly realizovány v malém laboratorním aparátu o průměru 10 cm. Emise NOx klesají s rostoucím tlakem, emise N2O vykazují maximum při tlacích 0,2 ? 0,5 MPa.
