Determination the Heat Price of a Combined Heat and Power Plant with the Energy Grade Theory

Abstract:

The combined heat and power plant furnish heat and electric, which are two different quality energy. And benefit returns to electric, benefit returns to heat and their trade off compose three methods to share the cost of the combined heat and power plant. Theory of energy grade is the thermodynamic viewpoint, which is not only considering the energy conservation, but also the energy matching. It takes into account all the quality and quantity of the utilized energy. In the present article, theory of energy grade is applied to analyze the heat usage of heat consumer. That takes the price of electric as basis. This method simplifies the calculation, has the reasonable theory foundation and meets the practice condition. It also reflects the idea of using energy according to the quality and high quality, high price
