美国政府的一些条例鼓励在工业上采用热电联产流程,使内部消耗后多余部分的热量用来发电,其电价颇具吸引力。这就要求在少量增加燃料费用的情况下最大量地发电。所谓联产,其定义为在供热的同时又进行发电,作为共同产品。这种方式其燃料效率很高(85～95%)。如果不要求供热,则联产也就不可能,此时作功的效率仅为30～40%。发电厂的情况就是如此。在加工工业中,采用透平联合流程系指多余废热全部用来发电,其燃料效率为60～
Some U.S. government ordinances encourage the use of CHP processes in industry to make excess electricity consumed after internal consumption of electricity, making the tariff attractive. This requires a maximum amount of power generation with a small increase in fuel costs. The so-called co-generation, which is defined as heating while generating electricity as a common product. This method of fuel efficiency is high (85 ~ 95%). If heating is not required, then co-production is impossible, and work efficiency is only 30-40% at this time. This is the case with power plants. In the processing industry, the use of turbine combined process refers to the excess waste heat used to generate electricity, the fuel efficiency of 60 ~
