【Abstract】 The approach to costing and evaluation for energy destruction is explored on the basis of exergy balance and cost balance equations, and a new exergoeconomic factor revealing the main sources of cost is proposed, combining the relevant evaluation indices for exergoeconomics, which can effectively evaluate the energyusing status and can point out the direction of energyusing improvement. An exergoeconomic evaluation index for energy systems based on the analysis of energy level is also proposed, which can evaluate the economic performances of energy systems from energylevel matching. The exergoeconomic analysis and improvement of a typical heat and power cogeneration system called CGAM are performed to demonstrate the availability of the proposed evaluation strategies.更多还原
