前言燃油锅炉采用低氧燃烧运行方式的研究工作在世界上已经有近20年的历史了。近年来各工业国家大部分燃油炉都可以稳定地把烟气含氧量降到1%以下甚至到0.2%(即过剩空气率ε在5%以下甚至到1%)运行,就是说供应燃烧的空气量已经很接近理论需要量了。它给锅炉运行带来了相当大的好处:减轻或基本避免了高温受热面(高温过热器) Preface The research work of using low-oxygen combustion operation mode in oil-fired boilers has been in the world for nearly 20 years. In most industrialized countries in recent years, most fuel ovens can stably reduce the oxygen content of flue gas to less than 1% and even to 0.2% (ie, the excess air rate ε is below 5% or even 1%), that is to say, The amount of air is very close to the theoretical requirements. It brings considerable benefits to boiler operation: Reducing or substantially avoiding hot surfaces (high temperature superheaters)
