Coal Consumption Calculation - CR4 Discussion Thread

03.12.2012  Lyn: Actually the question appears to be simple, but one really needs to predict coal consumption in a coal-fired plant, then the REAL answers are not simple. One would have to really know the REAL calorific value of each lot of coal, the precise load schedule each hour, and the base and incremental heat rates for the unit to get a realistic answer.

Calculation of Calorific Value of fuel..

Net Calorific Value (NCV) or lower heating value (LHV) or lower calorific value (LCV) is determined by subtracting the heat of vaporization of the water vapour from the higher heating value. It assumes water vapour leaves with the combustion products without fully being condensed. Fuel should be purchased based on NCV. Conversion of GCV to NCV can be done with below formula :-GCV = NCV + 584 ...
