WebSep 1, 2024 · 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 megajoules per kilogram (MJ/kg). A Btu is the amount of heat that will warm approximately 0.12 U.S. gallons—a pound of water—by 1 degree Fahrenheit at sea level. WebJan 29, 2024 · Volatile matter includes any material that is liberated from the coal at high temperatures. In the case of coal, the volatile matter may include sulfur and hydrocarbons. Heating Value: Bituminous coal provides approximately 10,500 to 15,000 BTU per pound as mined. Availability: Bituminous coal is abundant.
All in all, the higher heating value of hydrogen is 18.2% above its lower heating value (142 MJ/kg vs. 120 MJ/kg). For hydrocarbons, the difference depends on the hydrogen content of the fuel. For gasoline and diesel the higher heating value exceeds the lower heating value by about 10% and 7%, … See more The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it.
