Hydrogen
hydrogen calorific value is 150000 kJ/kg
Carbohydrates
Blast furnace calorific value is 780 Kcal/hr
The water gas has a high calorific value because it produces immense heat during its combustion.
Anthracite has the highest calorific value. and South African coal is best in the world.
The substance with the highest calorific value is generally considered to be hydrogen, which has a calorific value of about 141.9 megajoules per kilogram (MJ/kg) when combusted. In practical terms, when comparing traditional fuels, acetylene has one of the highest calorific values at around 50 MJ/kg. However, for conventional fuels, gasoline and kerosene also have high calorific values, ranging from 44 to 47 MJ/kg.
8600 kcal/m3 is the calorific value of CNG (Compressed Natural Gas) Submitted By Sanjay Jangid
Coal
calorific value of producer gas is 05 MJ m− 3 Reference http://www.kayelaby.npl.co.uk/chemistry/3_11/3_11_4.html Thanks
The calorific value of petrol/gasoline (and also its gas but it might be slightly different) is apprx. 50 kilojoules/gram of complete combustion.
The calorific value of LPG (liquefied petroleum gas) is approximately 46,000 kilocalories per kilogram.
