摘要

利用已有的广义火用平衡和成本平衡方程,研究了1 000 kW燃气轮机热电联产系统中部件年化成本对生产成本影响的热力学问题。通过求解一个预定义的热电联产系统CGAM问题,对典型的火用成本计算方法进行了比较。成功地识别了影响系统产品单位成本的要素。研究发现,产品的成本在很大程度上取决于其主要产品与系统产品相同的组件的年化成本的变化。另一方面,产品加权平均成本的变化与整个系统年化成本的变化成正比。

Exergoeconomic analysis of gas turbine cogeneration systems

A thermodynamic for the effect of the annualized cost of a component on the production cost in 1 000 kW gas-turbine cogeneration system was studied by utilizing the generalized exergy balance and cost-balance equations developed previously. Comparison between typical exergy-costing methodologies were also made by solving a predefined cogeneration system, CGAM problem. It was successful to identity the component which affects the unit cost of system's products decisively. It has been found that the cost of products are crucially dependent on the change in the annualized cost of the component whose primary product is the same as the system's product. On the other hand, the change in the weighted average cost of the product is proportional to the change in the annualized cost of the total system.
