摘要/Abstract

摘要： 入厂煤和入炉煤热值差是各火电厂十分关注的问题, 控制好入厂煤与入炉煤热值差对降低发电成本、促进电厂安全稳定运行有着积极的意义。从采样环节详细分析了入厂煤与入炉煤热值差大的原因,提出了相应对策，热值差指标得到较大改善。

Abstract: The thermal power plants pay high attention to the difference of the calorific value between asreceived coal and asfired coal. The proper control for the difference of the calorific value is of active significance to reduce the generation cost and promote the safe and stable operation of the power plant. Starting from the sampling, the reasons of the larger difference of the calorific value between asreceived coal and asfired coal were analyzed. The relevant countermeasures were proposed, and the index of the difference of the calorific value was improved considerably.

Key words: as-received coal, as-fired coal, difference of moisture content, difference of Calorific value, sampling, performance test
