摘要
本文结合某29MW锅炉低氮改造工程实例,介绍了烟气再循环技术原理,计算了空气预热器的热耗,分析了锅炉热效率、风烟系统等变化情况,对于类似燃气锅炉烟气再循环脱硝工程有一定借鉴意义。
Based on a 29 MW boiler low-NOx retrofit project, this paper introduces the principle of flue gas recirculation technology, calculates the heat consumption of air preheater,analyzes the boiler thermal efficiency and changes in air & flue gas system. It is worth learning for similar gas boiler flue gas recirculation low-NOx engineering.
