火电厂空冷机组水耗及煤耗性能分析

采用空冷机组是解决富煤贫水地区发电的有效措施,在中国西北部运用有着极为实际的意义,因此对中国燃煤电厂空冷机组的节水性能进行定量分析也具有现实意义。文章从国内外火电厂直接空冷机组与间接空冷机组发展的历史过程出发,在对近100个不同等级、不同冷却方式的火电项目样本进行统计分析的基础上,分别对直接空冷、间接空冷机组与常规火电机组的水耗及煤耗性能进行定量分析与比较,得出相应的水耗及煤耗结果,给出了水耗与煤耗的相关性,并给出相应的火电厂节水建议。

The Analysis & Research on Water-Consuming & Coal-Consuming Capability from Air-Cooling Unit in Coal-Fired Power Plants in China

Air - cooling unit in coal - fired power industry is an available measure for the area of rich - coal ＆ poor - water, so application in northwestward of China exists actual meaning very much. And quantitative research on water - consuming ＆ coal - consuming has the realistic significance about coal - fired power industry in China. At first, the development course of direct/ indirect air - cooling unit in coal - fired power plants has been introduced. Then through comparison direct/indirect air - cooling unit with conventional unit, some quantitative results can be gained through points of view of consuming water ＆ consuming coal on the basis of 100 statistic coal- fired power cases with different level, different cooling style as well as the pertinence between water - consuming and coal - consuming, at last, the relative suggestion has been given about water - consuming in coal -- fired power plants.
