摘　　要：随着经济的高速增长,能源消耗急剧增加,由此引发的环境污染日益严重。而循环流化床锅炉在燃烧的过程中可脱除S、N等有害气体,其排放物可达到国家的排放标准。本文通过对云天化电厂循环流化床锅炉的生产实践研究,探讨了循环流化床锅炉的炉温、分段燃烧、脱硫剂、气体在密相区停留时间、飞灰回燃等因素对CFB锅炉脱氮的影响,提出了有效控制NO生成的基本方法。With economic high growth,the energy is consumed and increased sharply,therefore the environmental pollution caused is serious day by day.And the circulating fluidized bed boiler can get rid of harmful gas such as S,N,etc.during the process of burning,discharging things can reach the national discharge standard.This paper,through researching production practices of Yuntian power plant circulating fluidized bed,discusses the furnace temperature of the circulating fluidized bed boiler,burning by stage,desulphurization pharmaceutical staying time of gas in dense looks district,ect^and these factors to the impact on CFB boiler denitrification.Then it proposes the basic method of controlling formation of NO_X effectively.
