纯燃煤发电机组供热改造,是指通过对纯燃煤机组的汽轮机和(或)锅炉进行适当的调整或改造,并相应改造制水、控制等系统,实现不同压力和温度等级参数的抽汽,由此将纯凝机组改造为抽凝机组,实施对外供热。纯燃煤供热功能的机组,一般是指经过改造的30万千瓦以下、10万千瓦以上的纯燃煤机组(全国约有8000万千瓦左右)。因为单机10万以下的纯凝机组已退出现役,由于相对于现有热电厂的供热机组和其它工业锅炉具有蒸发量大、热效率高、环保设施齐全、单位污染物排放量低、
Pure coal-fired generating units for heating transformation, refers to the pure coal-fired steam turbine and (or) boiler to make the appropriate adjustments or transformation, and the corresponding transformation of water, control and other systems to achieve different pressure and temperature level of the pumping parameters Steam, which will be transformed into pure condensing unit condensing unit, the implementation of external heating. Pure coal heating unit, generally refers to the transformation of the 300,000 kilowatts, more than 100,000 kilowatts of pure coal-fired units (about 80 million kilowatts nationwide). Because the unit below 100000 pure condensing unit has been out of active service, as compared with the existing thermal power plant and other industrial boilers have large evaporation, high thermal efficiency, environmental protection facilities, low emissions per unit of pollutants,
