摘　　要：晋能控股集团阳高热电有限公司两台1 207 t/h循环流化床锅炉采用了选择性非催化还原脱硝技术,脱硝区域布置在旋风分离器入口水平烟道处。在实际运行中,出现尿素耗量大的问题,电厂通过增加新型Y型超音速喷枪、喷枪移位、自动喷氨逻辑优化等改造措施后,每年可节约800多t尿素。Two 1 207 t/h CFB boilers in yanggao thermal power plant of jinneng holding group adopted selective non-catalytic reduction denitration technology,denitration area was arranged at the inlet horizontal flue of cyclone separator.In actual operation,the problem of urea consume much occurs,after some transformation measures such as adding new Y-type supersonic spray gun,displacing spray gun,optimizating automatic ammonia injection logic,more than 800 tons of urea can be saved every year.
