Influence of Ammonia and Hydrogen Peroxide Addition on NOsub(X) Emissions in the Flue Gas Channel of a 16 MW Coal Fired Fluidised Bed Combustor

摘要

Preliminary tests aimed at reducing NOsub(x) emissions in the flue gas channel of a 16 MW Atmospheric Fluidised Bed Combustor have been undertaken using the injection of NHsub/3//Hsub/2/Osub/2/ mixtures. A Further investigation of the potential of this technique was carried out with a chemical kinetic model involving homogeneous gas phase reactions. The modelled optimal conditions indicated that for NHsub/3//NO equal to 1.5, Hsub/2/Osub/2//NO equal to 0.7, a flue gas temperature of 690-710 degrees C and with the combustor being fired at an air factor of 1.2-1.3, ca. 70 percent NOsub(x) reduction can be achieved without high levels of residual NHsub/3/.
