近年来,应用计算机和可编程序调节器埘锅炉和加热炉进行节能控制越来越多,其目的都是为实现低氧燃烧,提高热效率,降低能耗和减少环境污染。锅炉和加热炉的热效率影响因素颇多,除与炉子种类、工艺状态、燃料热值、空气 In recent years, more and more energy-saving controls have been applied to computers and programmable controllers, boilers and furnaces for the purpose of achieving low-oxygen combustion, improving thermal efficiency, reducing energy consumption and reducing environmental pollution. The thermal efficiency of boilers and furnaces is affected by many factors, in addition to the type of furnace, process conditions, fuel heat value, air
