REDUCTION OF N2O IN A CIRCULATING FLUIDIZED-BED COMBUSTOR

[摘要] Nitrous oxide was injected at various locations in the combustion chamber of a circulating fluidized-bed boiler during combustion of fuels of different volatiles matter: coke, bituminous coal and wood. The reduction of the N2O injected was measured and the results were compared with calculations using available kinetic data. The reduction of the N2O introduced into the lower part of the combustion chamber was > 80%, but also, especially in wood combustion, at the top of the combustion chamber, a certain degree of reduction occurred, which is interpreted as being caused by volatiles combustion. The available kinetic data are still not sufficiently accurate for definite conclusions from calculations.
