Study and Application of New Indicators for Fuel Loss in Coal-fired Power Plant
This paper analyzes the two existing fuel loss indicators in coal-fired power plant,namely,the coal as received and the coal as fired.Considering that the coal yard storage loss is only a part of the fuel loss and that it is inconvenient to measure,and considering that the difference of heating values between the coal as received and the coal as fired is often distorted due to the fact that the coal currently burned in the boiler is not necessarily equal to the coal as received,from the perspective of heat balance and comprehensive heating value,and by defining the heat input and the heat output during a reference period,a series of new indicators,such as the heat loss between the coal as received and the coal as fired,the loss of the standard coal,the comprehensive difference of heating value between the coal as received and the coal as fired and the comprehensive heat rate,are proposed,and the criteria of judgment are discussed.As is shown by the research,these new indicators have integrated and truly reflected the coal amount and the heating value between the coal as received and the coal as fired and are relevant and applicable to the evaluation of coal management performance and can be used as a supplement to the General Rules of Guide for Fuel Balance of Thermal Power Plant.
