Abstract
In aspect of energy pricing,establishment principle of existing complementary equation does not consider the level of energy quality which means its irrationality. And there are no precise provisions in establishment principle for determining basis for energy pricing by using what kind of principle. Therefore,this paper proposes concept of energy quality coefficient which is used for improving establishment principle of the complementary equation and establishing the complementary equa-tion so as to make energy flow unit price match with its quality. Meanwhile,energy loss is re-priced as well. Taking some N300-16.67/537/537 thermal power unit for an example,this paper carries out thermo-economics analysis for accounting mode and compares with exergy energy coefficient method. Results indicate that exergy economic coefficients of the deaera-tor and No.7 low pressure heater change a lot while those of other equipments change a little which prove veracity of energy quality coefficient method. This method is also useful to be referred for pricing for different products of thermo-electric co-generation.关键词
