Calorific Value - an overview | ScienceDirect Topics
Calorific value is the heat energy released per unit mass of fuel burned as shown by Formula F71 Gross calorific value, or higher heating value (HHV), is the total heat released making no allowance for the latent heat required to vaporize the liquid water produced by the combustion process Hence it is a theoretical parameter and is rarely used

Gross & Net Calorific Values Gross CVor ‘higher heating value’ (HHV) is the CV under laboratory conditions Net CVor ‘lower heating value’ (LHV) is the useful calorific value in boiler plant The difference is essentially the latent heat of the water vapour produced Conversions – Units From kcal/kg to MJ/kg multiply kcal/kg by 0004187
There are two kinds of heat of combustion, called higher and lower heating value, depending on how much the products are allowed to cool and whether compounds like H 2 O are allowed to condense The values are conventionally measured with a bomb calorimeter They may also be calculated as the difference between the heat of formation ΔH ⦵
Bituminous - Bituminous coal contains anywhere from 45 to 86 percent carbon, giving it an even higher heating value than sub-bituminous High heat and pressure and between 100 and 300 million years are required to produce this type of coal About half of the coal produced in the US falls in this category with West ia, Kentucky and .
