火力发电厂氮氧化物减排

摘要

NOX is one of the main air pollutants. During the period of "The 12th Five-Year Plan", NOX is included in constraint index for the first time, and identified 10% emission reduction target. The thermal power plants discharge a great amount of NOX. Denitrification is a main means of NOX emission reduction. In the more mature denitrification techniques, SCR denitration technology has the advantages of high efficiency of flue gas denitrification, maturation, reliability, so it has become the main denitration technology in thermal power plants at present.%　　氮氧化物是造成大气污染的主要污染源之一,“十二五”期间,被首次列入约束性指标体系并确定了10%的减排目标。火力发电厂属于氮氧化物排放大户,脱硝是减少氮氧化物排放的主要手段。在较成熟的脱硝技术中,SCR 脱硝技术凭借其脱硝率高、成熟可靠等优点,成为目前火力发电厂脱硝的主流载体
