  • The Types of Coal: Composition, Usage, and Energy Value

    01/09/2021· 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 012 US gallons—a pound of water—by 1 degree Fahrenheit at sea level MJ/kg represents the amount of energy stored in aThe calorific value of coal represents gross calorific value (H G), which contains the latent heat of water vaporization When the latent heat of water vaporization is not included, the calorific value is called net calorific value (H N) The relationship between gross calorific value and net calorific value is expressed by the following eauation: (13) H N = H G − 600 (w + 9 h) where w isCalorific Value an overview | ScienceDirect Topics

  • Heat values of various fuels World Nuclear Association

    Heat Values of Various Fuels The heat value of a fuel is the amount of heat released during its combustion Also referred to as energy or calorific value, heat value is a measure of a fuel's energy density, and is expressed in energy (joules) per specified amount (eg kilograms)The calorific value of a fuel is the quantity of heat produced by its combustion – at constant pressure and under “normal” (standard) conditions (ie 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 itFuel Calorific Values | CNG Europe

  • Gross Calorific Value in Coal LECO Corporation

    The gross calorific value of coal, a solid fossil hydrocarbon fuel material, is most often used when calculating the total calorific value for a quantity of coal for fuel value purposes, or when determining the classification rank of the coal material The gross calorific value and sulfur value of the coal material can also be used to calculate whether or not the coal material meets regulatoryThe calorific value of coal is in the range of 25–35 MJ/kg There are three main types of coal: lignite, bituminous coal and anthracite Anthracite is the highest quality coal, as it has a carbon content of more than 90% and the highest calorific value Physically it is one of the hardest types of coal; the carbon content of bituminous coal is in the range of 70%–75%Net Calorific Value an overview | ScienceDirect Topics
