EMISSIONS OF NITROUS OXIDE (N2O) FROM FLUIDIZED BED BOILERS

• ABSTRACT Measurements of emissions of nitrous oxide (N20) have been carried out on two kind of fluidized bed boilers. One of them, a circulating fluidized bed boiler has been run with three kind of fuels at different operating conditions. The results of the measurements show that the emission of N20 depends on bed temperature and fuel. The temperature dependence is explained by the strong influence of temperature on the rate of destruction of nitrous oxide by radicals in the gas phase.
