某300MW循环流化床机组NO_x超低排放研究

Research of Ultra Low Emission of Nitrogen Oxides for a Circulating Fluidized Bed Boiler in a 300MW Unit

现役的循环流化床锅炉发电机组,NO_x排放浓度完全可以满足《火电厂大气污染物排放标准》(GB13223—2011)以及重点地区特别排放限值的要求。为了响应国家三部委联合下发《煤电节能减排升级与改造行动计划(2014—2020年)》的通知要求,进一步提升煤电高效清洁发展水平,开展现役的循环流化床机组NO_x实现超低排放(低于50mg/m^3)的研究工作具有十分重要的意义。

The NOx concentration of CFB Unit on active service all meet the standard requirement in ＂Emission Standard of Air Pollutants for Thermal Power Plants＂（GB 13223--2011）, also meet special emission limits in standard key areas in china. In response to the state three ministries jointly issued the ＂coal and electricity energy saving and emission reduction and upgrading and transformation plan （2014-2020）＂ （Energy [2014] No. 2093）, and further enhance the level of development of clean and efficient coal. It is of great significance to carry out research work on CFB unit to achieve ultra-low NO, emissions.
