12-05-2021· The basic formula for a weighted average where the weights add up to 1 is x1(w1) + x2(w2) + x3(w3), and so on, where x is each number in your set and w is the corresponding weighting factor. X Research source To find your weighted average, simply multiply each number by its weight factor and then sum the resulting numbers up, the same way you would take the average of any other …
The gross calorific value (GCV) of coal is a key yardstick for many end users purchasing coal from suppliers, as it provides a clear measure of the useful energy content of a coal. Gross calorific value, also known as higher heating value (HHV), is determined by measuring the heat released when coal is burned in a constant-volume.

The given values are for fuels with the given density. The variation in quality may give heating values within a range 5 -10% higher and lower than the given value. Also the solid fuels will have a similar quality variation for the different classes of fuel. 1 Btu (IT)/lb = 2.3278 MJ/t = 2327.8 J/kg = 0.55598 kcal/kg = 0.000646 kWh/kg.
Since 1961, the average gross calorific value of the domestic thermal coal supply has almost halved to 3300 kcal/kg. This decline will continue as the share of inferior Indian coal is expected to increase progressively. Consequently, coal consumption per unit power generation and hence ash amount and emissions are observed to be continuously rising.

21-01-2013· Since our current average price is 30 to 60 per cent lower than the international prices, a sudden entry to GCV will affect the power sector badly. Hence we are adopting it in phases." Currently, Indian coal is classified on the basis of UHV (useful heat value) into seven grades from A-G. UHV is based on ash and moisture contents for non-coking coals in line with the Centre directive.

10-01-2009· 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 ...
06-03-2015· Coal, as it is commonly known, is a solid fossil hydrocarbon fuel material. The gross calorific value of coal is frequently used when determining the total calorific value for a specific amount of coal for fuel value purposes or when establishing the rank of classification of the coal material.
The most important quality parameter for coal is its heat value referred to as 'Gross Calorific Value' or GCV. Pricing of coal by coal companies and pricing of energy by generating companies depends significantly on the GCV of coal. GCV depends on the location from which samples are collected and the method used for its measurement.

26-07-2021· Weighted average is the average of a set of numbers, each with different associated "weights" or values. To find a weighted average, multiply each number by its weight, then add the results. If the weights don't add up to one, find the sum of all the variables multiplied by their weight, then divide by the sum of the weights.
