420t/h无烟煤锅炉烟煤改造应用

Application of Bituminous Coal Modification in Anthracite Boiler

介绍某一次中间再热超高压自然循环汽包炉将设计煤种由无烟煤改为烟煤,对燃烧设备、过热器、再热器、省煤器以及制粉系统进行改造的方法。

This paper introduces the reconstruction and modification work of combustion equipment, superheater, reheater, economizer and coal pulverizing system for a superhigh pressure intermediate reheat natural circulation drum boiler, which require switching anthracite coal to bituminous coal as designed coal.
