Abstract

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
