海水淡化过程的统一性性能评价指标

THE UNIFIED INDEXES OF EVALUATING THE PERFORMANCE OF DESALTING PROCESSES

本文分析了各种脱盐过程的常用性能评价指标存在的不可比问题 ,并以电量为基准 ,提出了各种脱盐过程的热力学性能、一次能源消耗率和一次能源效率指数的简便、通用的计算方法 ,其计算结果具有可比性 ,并据此研究了热电联产海水淡化的能源成本问题 。

The paper analyses the incompatibility among the conventional indexes of evaluating the performance of desalting processes with different mechanisms. A simple and universal method of calculating the thermal performances, unit fuel consumption rates and premier energy efficiencies of these desalting processes are proposed, and those results are comparable one another. And energy cost and price of cogeneration desalination is calculated on the basis of those of electricity supply. Some worth conclusions are given.
