Calorific Value of Diesel Petrol & Coal Fuels Heat Of 15Shares In power generation the calorific value of fuel is prime factor. Use of fuels having high heat of combustion gives best output in terms of cost of electricity or energy generated. When we generate electricity in steam power plant we have to burn fuel like coal, petroleum oil or flammable gases. In thermal powersLecture 2 Characterisation of Fuels nptel.ac.inLecture 2 − Characterisation of Fuels. Fuel is a source of energy. Industrial growth, among other factors, is largely dependent on consumption of energy. Large amount of energy requirement can only be met by fossil fuel reserves, though
calculation of gross calorific value of coal,What is the exact difference between GCV & NCV? QuoraGross calorific value (GCV) Coal: 1.052 Since most gas burning appliances cannot utilize the heat content of the water vapor, gross calorific value is of little interest. Fuel should be compared based on the net calorific value. This is especially true for natural gas, since increased hydrogen content results in high water formation duringHow do we calculate the calorific value of a fuel?
