Abstract: In order to evaluate the efficiency of cogeneration power plants as the main body of the market economy, taking the fuel input and product output of cogeneration units as the study objectives, the concept of economic benefits coefficient is proposed by considering the economic value of the heating and generating capacities of cogeneration units. The calculation model of the concept is also established. From the perspective of macro economy, the method based on the economic value generated by unit fuel consumption is proposed to assess the energy efficiency of cogeneration power plants. It overcomes the disadvantage of the traditional method that uses the quantity and quality of energy to analyze the cogeneration unit cost allocation, and has some market economics significance. In addition, a sample calculation is given based on a 300-MW extraction condensing turbine. The results indicate that the calculation method is simple and practical, and can provide effective solution to reasonable heat and power pricing and scheduling.

Key words: heat and power cogeneration, product, coefficient of economic benefits, energy efficiency
