โœฆ Synopsis

Combustion (burners, combustion systems)

emission calculated using this unsteady flamelet model is relatively close to measurements available from a previous study, while steady flamelets overpredict the NO emission by an order of magnitude.

During coal gasification, the removal of H 2 S from the hot product gases using limestone generates calcium sulfide, a potentially hazardous chemical requiring treatment before disposal. One approach is to convert the CaS to CaSO 4 via oxidation in a topping cycle pressurized fluidized bed combustio

sulfur retention by limestone (CaCOa) under fluidized bed combustion conditions is the net effect of a competition between sulfur capture and sulfur release during which the composition of the Ca surface changes continuously between CaO, CaS and C&04, the ultimate product being CaSO4.

Emission of CO, NO x , N 2 O and SO 2 from a 71 MW PFBC was continuously observed for 8 days while the plant load, the level of coal load, the concentration of emission gases, total pressure, and temperature varied dynamically. Prediction of concentrations of such gases are attempted in this paper t
