Abstract
For a municipal incinerator, it is crucial to perform combustion in view of mixing, reaction and heat transmission of combustion gas for reducing the generation of micropollutants such as dioxins, nitrogen oxides and so on. The purpose of this work, therefore, is to recognize the degree of effect of each factor influencing gaseous combustion by actual incinerator. For the tests, inspiring of secondary air into the furnace in addition to water spray into the furnace and exhaust gas circulation was performed, and the variation of CO and NOx concentration was measured. As a result, CO and NOx concentration was controlled at low level.
