Jan 01, 1983· A new formula for calculating the calorific value of coal from its ultimate analysis has been obtained by regression analysis of a data bank consisting of data on 775 samples of coals of all ranks. It yielded zero average difference between observed and calculated values and a standard deviation of 129 Btu/lb (300 kJ/kg).
In determination of ECR, Weighted Average Gross calorific value of coal as received, in kcal per kg for coal based stations less 85 kCal/kg on account of variation during storage at generating station is being considered by the Commission. Accordingly, less 85kCal/kg has been considered in GCV while arriving at the annual coal consumption.
Weighted average GCV = (e/a) (kCal/Kg) 13. Consequent upon the revision of weighted average price of coal to Rs / MT and weighted average GCV (as billed) of coal to kCal/kg as above, the receivable component of working capital allowed in order dated shall stand revised as under: (`in lakh)

Jan 29, 2020· Hard vs. Soft: Coal falls into two main categories: hard and soft. Soft coal is also known as brown coal or produces more hard coal than any other country by a factor of about three. The whopping 3,162 million metric tons of hard coal produced by China dwarfs the output of the second and thirdranked producers—the at 932 million metric tons and India at 538 million metric ...
How to Calculate the Coal Quantity Used in a Power Plant. . Energy content of coal is given in terms of KiloJoules (kJ) per Kilogram (kg) of coal as the Gross calorific value (GCV) or the Higher Heating value (HHV) of coal. This value can vary from 10500 kJ/kg to 25000 kJ/kg depending on the quality and type of the coal. Chat Online »
Coal is the primary fuel for producing Electricity. Some of the characteristics of coal have profound influence on the day to day working and economics of the power plant. This article discusses Calorific Value and Moisture. Calorific value is the most important parameter that determines the economics of the power plant operation. It indicates the amount of heat that is released when the coal ...
