关于火电厂绿色评价指标的探讨

由于传统的“供电煤耗率”并不能反映机组对环境影响的大小，因此提出了“绿色供电煤耗率”这个概念，并采用“绿色性能因子”来评价火电机组性能包括环境因素在内的总体表现。为了进一步诊断出机组环境损耗的真正原因，为运行提供指导，提出了，“环境损耗因子”、“环境局部影响因子”等概念。最后以国产两台燃烧不同煤种的600MW机组为例，利用所提出的绿色指标，对机组在某段时间内的运行状况分别进行了全面评价并作了对比分析。

STUDY ON THE GREEN EVALUATION INDEX FOR COAL-FIRED POWER PLANT

The‘coal consumption rate＇ haven＇t reflected the environment＇ s influence of a coal-fired power generation unit , so the index named as ‘green coal consumption rate＇ is put forward in this paper. The concept of ‘green operation performance factor＇ is introduced to evaluate the unit performance on the basis of environment＇s factors. In order to reveal the factors leading to environ-ment damage of the power generating unit, the ‘environment damage factor＇ and ＇environment part influence factor＇ are utilized. Taking two domestic 600MW power generation unit of buming different coal as an example, its status and operation quality are evaluated in detail and compared by using green index.
