摘要:

通过分析当前我国燃气内燃机排放的烟气成分,发现氮氧化物排放值已经无法满足日益严格的环保要求,寻找一种新的脱硝工艺路线来解决内燃机的排放问题势在必行。经过借鉴传统的烟气脱硝方法,筛选出一种适合燃气内燃机分布式能源系统的烟气脱硝方式——选择性催化还原法(SCR)。此方法提升了脱硝效率,解决了燃气内燃机分布式能源系统氮氧化物排放问题。通过流场模拟及工程应用,证明该方法相对于传统方式更具先进性。

Abstract:

After analyzing flue gas emitted by internal combustion engines in China, the NOx emission value can not meet the increasingly stringent environmental protection requirements. It is imperative to find a new process of denitration technology to solve the emission problem of the internal combustion engine.Taking traditional flue gas denitration methods as references, a SCR method suitable for gas flue denitration of  distributedenergy system internal combustion engines is selected.The method improves the denitrification efficiency and solves the NOx emission problem of distributedenergy system internal combustion engines,which is validated by flow field simulation and engineering application.It proves that the method is more advanced than the traditional way.
