是一样的，在脱硝装置中喷枪，喷头的作用一样，尿素只是脱硝剂而已，所以尿素喷嘴和脱硝喷枪作用是一样的但不排除有例外情况，比如干法脱硫、炉内SNCR脱硝技术、炉外SCR脱硝低尘布置等等，脱硝和脱硫设施有可能会与常规布置在除尘器的上游或下游相反的位置还有就是现在为了控制PM2.5，湿式除尘逐渐会推广应用，顺序有可能又不同过程为：脱硝（在锅炉尾部过热器后）--除尘（在锅炉尾部烟道）--脱硫（在除尘器后）先是脱硝装置，布置在在锅炉尾部过热器--除尘（通常是两套除尘，先是电除尘，后是布袋）--脱硫（效果较好的一般是湿法脱硫）用S污水处理一体化设备厂家排名CR法脱硝,脱硝剂的种类还是比较多的,一般的有：液氨、尿素、氨水等几种.因为液氨涉及到卫生防护距离,但是效果比较好。
