        常安热电SNCR脱硝系统

        一、项目介绍:常安热电2×75t/h蒸汽锅炉SNCR脱硝系统
        该项目是为常安热电2×75t/h蒸汽锅炉进行烟气脱硝,锅炉烟气量86000Nm3/h,含氮量300mg/Nm3,采用SNCR脱硝系统。在下列条件下,出口NOx含量不高于100 mg/Nm3,氨的逃逸率不大于8ppm。

        二、工艺介绍:SNCR脱硫系统
        选择性非催化还原法(SNCR)烟气脱硝?#38469;?#26159;目前主要的烟气脱硝?#38469;?#20043;一。在炉膛850~1250℃这一狭窄的温度范围内、在无催化剂作用下,NH3或尿素等氨基还原?#37327;?#36873;择性地还原烟气中的NOx,从而达到脱硝的目的。
