A Review of Coal and Water Resources of Pakistan
lignite coal is found in Asia and Pakistan is tops lignitic coalbearing countries in Asia. 97% of coal reserves of Pakistan belong to lignite and remaining only 3% are subbituminous to bituminous. So far, out of an estimated 475bt of subbituminous and lignite reserves of the world, % occur in Asia, % in Europe, % in
Fuel Calorific Values
The calorific value of a fuel is the quantity of heat produced by its combustion – at constant pressure and under "normal" (standard) conditions ( to 0 o C and under a pressure of 1,013 mbar). The combustion process generates water vapor and certain techniques may be used to recover the quantity of heat contained in this water vapor by condensing it.
The Types of Coal: Composition, Usage, and Energy Value
Dec 17, 2018· The stored energy potential within coal is described as the "calorific value," "heating value," or "heat content." It's measured in British thermal units (Btu) or millijoules per kilogram (MJ/kg). A Btu is the amount of heat that will warm approximately gallons—a pound of water—by 1 degree Fahrenheit at sea level.

Bituminous Coal Characteristics and Applications
Jan 14, 2019· Bituminous coal combustion releases more pollution into the air than subbituminous coal combustion, but due to its greater heat content, less of the fuel is required to produce electricity. As such, bituminous and subbituminous coals produce approximately the same amount of pollution per kilowatt of electricity generated.

For gasoline and diesel the higher heating value exceeds the lower heating value by about 10% and 7% respectively, and for natural gas about 11%. A common method of relating HHV to LHV is: where H v is the heat of vaporization of water, n H 2 O,out is the moles of water vaporized and n fuel,in is the number of moles of fuel combusted.
