分解炉分级燃烧降氮脱硝技术的研究与应用

摘要

The combination of high temperature combustion technology of low NOx and decomposing furnace system with big cubage has the characteristics, such as the high heat efifciency, equality of decomposing furnace temperature, nitro-gen removal and denitration, low concentration of NOx emission. The paper introduces the application of high temperature&graded combustion technology in cement kiln, focusing on the application principle of graded combustion, nitrogen removal and denitration in decomposing furnace system and popularizing value.%低NOx高温燃烧技术与大容积分解炉系统有机结合，具有热效率高、分解炉温度分布均匀、降氮脱硝、NOx排放浓度低等特点。文章介绍了高温分级燃烧技术在水泥窑中的应用，重点分析了分级燃烧、降氮脱硝在分解炉系统中的应用原理，以及推广的价值。
