摘　　要：大同发电有限公司作为大同市重要热源点,已然满足不了日益增长的供热需求。通过将二期8号机组进行低位能分级混合供暖技术改造,增设高背压凝汽器及连通管打孔抽汽等改造,提高了空冷机组的供热能力,使冬季供热能煤耗由28.45kg/GJ降至13.08kg/GJ,二、三期供热面积增加至3660万m2。Datong Power Generation Co.,Ltd.,as an important heat source in Datong City,has been unable to meet the increasing heating demand.Through the technical transformation of low energy graded mixed heating of Phase II#8 unit and the addition of high back pressure condenser and connected pipe drilling steam extraction,the heating capacity of air cooling unit has been improved,and the heating energy and coal consumption in winter has been reduced from 28.45kg/GJ to 13.08kg/GJ.The heating area of the second and third phases will be increased to 36.6 million square meters.
