        常安熱電SNCR脫硝系統

        一、項目介紹:常安熱電2×75t/h蒸汽鍋爐SNCR脫硝系統
        該項目是為常安熱電2×75t/h蒸汽鍋爐進行煙氣脫硝,鍋爐煙氣量86000Nm3/h,含氮量300mg/Nm3,采用SNCR脫硝系統。在下列條件下,出口NOx含量不高于100 mg/Nm3,氨的逃逸率不大于8ppm。

        二、工藝介紹:SNCR脫硫系統
        選擇性非催化還原法(SNCR)煙氣脫硝技術是目前主要的煙氣脫硝技術之一。在爐膛850~1250℃這一狹窄的溫度范圍內、在無催化劑作用下,NH3或尿素等氨基還原劑可選擇性地還原煙氣中的NOx,從而達到脫硝的目的。
