Integrated technology of desulfurization and denitration in CFB boilers
摘要
为满足《火电厂大气污染物排放标准》(GB 13223—2011)的要求
现役循环流化床(CFB)发电机组在避免增加炉外脱硫脱硝设备的前提下
充分挖掘CFB锅炉特有的环保潜力
首次提出采用炉内一体化耦合脱硫脱硝的技术路线。实际应用结果表明
通过增加锅炉受热面、提高分离器效率、优化二次风布置及石灰石输送系统等综合性改造以及燃烧优化调整试验
可以实现SO2、NOx排放均小于200mg/m3(6%O2)的目标
经济和环境效益明显。
Abstract
In order to meet the requirements of newemission standard of air pollutants for thermal power plants(GB13223-2011)
the environmental protection potential of the CFB boilers was fully dug and the integrated technology of desulfurization and denitration in furnace was proposed
on the premise of not adding more desulfurization and denitration equipments at outside of the current boiler.The practical application shows that
through comprehensive transformation measures(like increasing the heating surface
enhancing the separator efficiency
optimizing the secondary air distribution and lime stone delivery system)and combustion optimization adjustment experiment
the SO2and NOxemission can be decreased to lower than 200mg/m3(6%O2).
