摘要
Abstract
In the stage of low load,denitration systems of two boilers in Guangdong Zhuhai Jinwan power generation co., ltd. (hereinafter referred as Jinwan power plant)was out of service due to low gas temperature which caused discharge be-yond standards of flue gas pollutants. In order to ensure emission of NOx satisfy the newest environmental protection re-quirement at the time of low load,Jinwan power plant conducted denitration transformation for the boiler which was firstly to add denitration device for the tail flue of boiler and carry out classification transformation for the economizer,then make adjustment for low nitrogen combustion and optimization on start and stop of the unit. After transformation,per hour aver-age material quality concentration of NOx at the exit of chimney is less than 30 mg/m3 in standard condition and operational percentage of denitration device in 40%~60% load stage reaches to 100% which effectively reduces emission of pollutants and well solves the problem of the denitration system being unable to be put into operation for reason of low gas tempera-ture.关键词
