燃气低氮和中心回燃锅炉及铸铁锅炉的低氮改造浅析

Low NOx Emission Retrofit of Central Reverse Flame Boiler and Cast-Iron Boiler

介绍目前主流燃气低氮燃烧技术,对比分析了不同燃烧技术的优缺点。针对中心回燃锅炉和铸铁锅炉的结构和燃烧特点,提出适合于两种锅炉低氮改造的可行方案。

Present the current mainstream gas low NOx combustion technology,the advantages and dis-advantages of different combustion technologies are compared and analyzed.In view of the structure and com-bustion characteristics of central reverse flame gas-fired boiler and cast-iron boiler,provides the feasible scheme suitable for the Low NOx emission retrofit of two types of boilers.
