摘要
介绍NO_x的危害。结合工程实例,探讨燃气热水锅炉低氮排放技术改造,从更换锅炉燃烧器、增加FGR系统(烟气再循环系统)及更换相关控制系统方面进行改造。给出改造后的设备清单、参数及系统图。
The hazards of NOx are introduced.Combined with engineering examples,the technical transformation of low nitrogen emission from gas-fired hot water boilers is discussed.The transformation is carried out in terms of replacing boiler burners,adding flue gas recirculation(FGR)system and replacing related control systems.The reformed equipment list,parameters and system diagram are given.
