Optimization on SNCR Denitration System in Municipal Waste Incinerators
摘要
Abstract
This paper uses computational fluid dynamics simulation software FLUENT to study numerical simulation and opti-mization on selective non-catalytic reduction (SNCR)system in municipal waste incinerators under different working condi-tions. Results indicate that reductant from the lower SNCR injection nozzle is fully mixed with flue gas which means better denitration effect,in the case of constant total flow of reductant,an increase of flow in the lower SNCR injection nozzle is useful to improve SNCR denitration efficiency and matching of 6:3:1 makes denitration efficiency of the waste incinerator reach 53.3%. In addition,compared to other ejection velocity,mixed flow effect of the original ejection velocity condition is better and denitration efficiency is 5 1.7%.关键词
