SNCR/SCR联合脱硝技术在410t/h电站锅炉上的应
用研究的开题报告
摘要:
随着环保意识不断增强,电力工业过去使用的高硫煤、高灰煤和
质煤等污染重的燃料逐渐被淘汰。然而,新型燃料价格昂贵,核电站缺
乏、水电站的资源有限,因此仍需要使用常规燃料。常规燃料含硫量高,
烟气中SO2的排放量也相应较高,直接将其排放到大气中将对环境带来
严重污染。
脱硝技术是减排的重要环节之一,SNCR/SCR联合脱硝技术在电站
锅炉上应用广泛,但是其适用性和优化方案需要针对不同锅炉进行研究。
本文以某410t/h电站锅炉为研究对象,通过实地调研和数据分析,
论证了SNCR/SCR联合脱硝技术在该锅炉上的适用性,并通过建立模拟
模型进行了优化方案研究。
关键词:电站锅炉,常规燃料,SNCR/SCR脱硝,优化方案
