A Technical Scheme of NO_X-controling for CFB Boiler
Chen Yaohua;Shanxi Yaoguang Coal and Electricity Co.,Ltd.;
Shanxi Yaoguang Coal and Electricity Co.,Ltd. actively responded to the requirements of the state environmental protection for # 1 and # 2 unit denitration system for ultra low emission upgrades,this project has be completed by Shanxi Huarentong technology Co.,Ltd. as a General contractor. The transformation still choosed urea solution for reducing agent,implementationd expansion about the dilution water pump、urea and the dilution water line on the basis of the original preparation system,completed more fine control for compressed air line and the urea solution by using modular design,at the same time,the spray position of the spray gun on the horizontal flue was optimized,and arranged an appropriate number of spray guns in the appropriate position in the furnace,improved the SNCR control system to make the control more accurate,so as to achieve the highest efficiency of denitration with the most economical operation mode.
