摘　　要：结合典型实例,对大型工业抽汽机组的运行状况进行了剖析,对不同供汽方式下的能耗损失进行了定量计算。结果表明,目前常用的几种工业抽汽方式均存在一定的问题,影响机组经济性降低。其主要原因是供汽参数和用户用汽参数不匹配,导致蒸汽节流损失增加,蒸汽的作功能力降低。针对以上各种问题,制定针对性的优化方案,改造后提高了机组的经济性。Combined with the typical example, the operation status of large-scale industrial extraction unit is analyzed,and the energy loss under different steam supply modes is calculated quantitatively. The results show that there are some problems in the several kinds of industrial extraction methods, which affect the economy efficiency of the unit.The main reason is that the steam parameters and the user does not match the steam parameters, resulting in increased steam throttle loss, steam work capacity reduced. In view of the above problems, the development of targeted optimization program, after transformation to improve the unit＇s economy.
