gross calorific value
Quantity required to produce 1 unit of energy. It may be calculated for thermal power plant by dividing Plant Heat Rate by GCV of Coal.
Coal is a form of energy created by burning the coal that is mined. Coal is part of the problem because of the greenhouse ases created by burning it. If we continue using coal at the current rate we will soon run ot.
what is the full form of GAL
what is the full form of UKG ,LKG class
just somedisadvantagesof coal power .It takes YEARS for debrie to form into coal (debrie=grass dead animals etc.) .It is NON renewable .It is NOT an eco friendly energy source
to produce 1 ton of steam how many GCV of coal is required?
yyyyyyyyyyyyyyy=GCV-(IM/9+5)*53
Gross calorific value of coal

By Dulong formula
GCV, gross calorific value, is the quantity of heat produced by combustion. UHV, useful heat value, is the gradation of non-coking coal.
(uhv + 3645 -75.4 m)/1.466
Weighted average of oil consumed:(rate of oil A * quantity of oil A) + (rate of oil B * quantity of oil B)Quantity of oil (A+B)GCV of oil consumed:(GCV * quantity of oil A) + (GCV * quantity of oil B)Quantity of oil (A+B)
Useful heat value(UHV) pricing mechanism of coal deducted ash and moisture content from standard formula and in this coal is categorised into 7 grades. Gross calorific value(GCV) of coal has 17 grades and prices are linked to the actual calorific value/quality of coal-by latika joshi
Theorotical value can be calculated using the results of ultimate analysis of coal . Based on the GCV of combustible value of coal.
Coal If we know the ultimate analysis of fuel, we can easily calculate its GCV. The basic principle is that there are only 3 components in a fuel which generate heat. These are: Carbon, Hydrogen and Sulphur. According to Dulong's formula gross calorific value of a fuel is; GCV = ((35.5 x C + 114.8 x H + 9.5 x S - 14.5 x O) x 1000) / (100 x 4.1868) Each multiple of carbon, hydrogen and sulphur represents heat generated by its one mole. The formula gives GCV in kcal/kg. Simple isnt it !
