摘要
N2O(氧化亚氮)是一种具有破坏臭氧层和造成大气温室效应双重作用的大气污染物质。煤炭燃烧,特别是800~950℃低温流化床燃烧,会排放大量的N2O。发展和普及流化床锅炉必须解决N2O的排放控制问题。文中概要地阐述了流化床燃烧过程中N2O的来源和生成、分解机理,影响N2O生成量的各种因素,以及减少N2O排放量的技术措施。
N 2O(nitrous oxide) is an atmospheric polluting material with a dual action of destroying ozonosphere and giving rise to atmospheric greenhouse effect.When coal burns,in particular,on the 800~950 ℃ low temperature fluidized bed,a great amount of N 2O will be discharged.In order to develop and popularize fluidized bed boiler,N 2O emission problem must be solved.This paper briefly describes the source,formation and decomposition mechanism of N 2O,and various factors affecting the amount of N 2O formation as well as the technical measures of reducing N 2O discharge.
