SCR脱硝系统对锅炉设备的影响及对策

Effect of SCR Denitrification System on Boiler Equipment and Countermeasure

2014年1月1日,我国实施了新的《火电厂大气污染物排放标准》,锅炉装置必须按国家要求的排放标准进行排放。2014年3月化肥厂动力车间对C锅炉进行脱硝改造,以满足我国新的《火电厂大气污染物排放标准》的排放要求。SCR脱硝效率可高达90%以上,是目前最好的脱硝技术。但是,SCR脱硝后生产的副产品对锅炉设备有一定的危害。

On January 01,2014,China implemented the new Air Pollutant Discharge Standards for Thermal Power Plants,and our boilers must discharge according to the national emission standards.In March 2014,the power plant of chemical fertilizer plant carried out denitrification transformation of C boiler to meet the emission requirements of China’s new 'Air Pollutant Emission Standard for Thermal Power Plants'.SCR denitrification efficiency can be up to 90%,which is the best denitrification technology at present.However,by-products produced after SCR denitrification do harm to boiler equipment.
