Approximate Lower Heating values of standard grades of coal:

Anthracite Coal is very shiny, hard black coal, high carbon content and energy density, repels moisture, for domestic industrial uses, including smokeless fuel
Bituminous Coal is softer and shiny, moisture content is 8 -20%, possible for coking coals, volatile matter from 16% - 40%, can be used for thermal or metallurgical applications
Sub-bituminous Coal is soft and black with energy density lower than bituminous coal, most common type for electricity generation
Lignite Coal is light brown with high moisture content and low energy density, used mainly for electricity generation

Anthracite Coal - Anthracite coal is available in a number of different grades.
Coal - Classification - Classification of coal based on volatile matter and cooking power of clean material.
Combustion of Fuels - Carbon Dioxide Emission - Environmental emission of carbon dioxide CO₂ when combustion fuels like coal, oil, natural gas, LPG and bio energy.
Food - Calorific Combustion Values - Combustion heat values of some foods.
Fossil and Alternative Fuels - Energy Content - Net (low) and gross (high) energy content in fossil and alternative fuels.
Fuels and Chemicals - Autoignition Temperatures - Autoignition points for fuels and chemicals like butane, coke, hydrogen, petroleum and more.
Gaseous Fuels - Chemical Composition - Chemical composition of gaseous fuels like coal gas, natural gas, propane and more.
High and Low Heat Values - The gross (high) and net (low) heating values.
Nitrogen Oxides (NO_x) Emission from Fuels - Emission of Nitrogen Oxides - NO_x - with combustion of fuels like oil, coal, propane and more.
Solids - Specific Heats - Common solids - like brick, cement, glass and many more - and their specific heats - in Imperial and SI units.
Stoker Classification - Coal stokers classified on basis of coal burning capacities.
