摘　　要：北方某生物质电厂现有3×75 t/h+3×12 MW抽凝式汽轮发电机组,供热面积166万平方米,采用抽汽高温间供方式。机组配套建设一座自然通风冷却塔,冷却塔余热尚未利用,大量的余热排放到大气中,造成了能源浪费。回收生物质电厂余热为城市集中供热,可谓变废为宝,降低企业供热成本,提高企业运行的经济性。A biomass power plant in the north currently has a 3×75 t/h+3×12 MW extraction condensing turbo-generator set,with a heating area of 1.66 million square meters.The unit is equipped with a natural ventilation cooling tower.The waste heat of the cooling tower has not yet been used,and a large amount of waste heat has been discharged into the atmosphere,resulting in waste of energy.Recycling waste heat from biomass power plants to provide centralized heating in the city can be described as turning waste into treasure,reducing the cost of heating the enterprise and improving the economical operation of the enterprise.
