Abstract
PURPOSE: To economically remove nitrogen oxide, by forming quicklime by adding lime powder to a fluid layer type incinerator, and by reducing nitrogen oxide by the catalytic action of quicklime.
CONSTITUTION: Inactive grain G, such as, sand etc. is filled to a bottom of a furnace body 2 of a fluid layer type waste matter incinerator 1. Inactive grain G is fluidized by heating to shape a fluid layer F, and matters M to be burnt are continuously burnt. When feeding lime powder P at that time, the powder is pyrolyzed by the heat of inactive grain G, thus forming quicklime. Nitrogen compounds contained in the matters M to be burnt and nitrogen compounds created from O2 and N2 in air when high temp are reduced to innoxious nitrogen gas by CO formed in a combustion process by the catalytic action of the quicklime, and blown off to an upper space S
