摘　　要：分析了220 t/h燃煤锅炉改烧天然气后可能出现的情况,计算和对比了不同给水温度下锅炉的热力数据,从而得出改动受热面是较合适的方案。在改烧天然气后,可提高锅炉的出力,为燃煤锅炉改燃天然气提供了经验。Possible situations that may be encountered by a 220 t/h coal fired boiler after having switched to burning natural gas are described; thermodynamic data of the boiler for various feed water temperatures are calculated and compared, pointing out that a change of the heat deliver）, surface is a suitable way of doing the job. After switching to natural gas, the boiler＇s output may increase. This may serve as a reference for later similar retrofit work.
