Approximate Lower Heating values of standard grades of coal:
|Coal Grade||Heating Value|
|High-volatile bituminous A||13090||30499|
|High-volatile bituminous B||12130||28262|
|High-volatile bituminous C||10750||25047|
- 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
Boiler house topics, fuels like oil, gas, coal, wood - chimneys, safety valves, tanks - combustion efficiency.
Anthracite coal is available in a number of different grades.
Classification of coal based on volatile matter and cooking power of clean material.
Environmental emission of carbon dioxide CO2 when combustion fuels like coal, oil, natural gas, LPG and bio energy.
Combustion heat values of some foods.
Net (low) and gross (high) energy content in fossil and alternative fuels.
Autoignition points for fuels and chemicals like butane, coke, hydrogen, petroleum and more.
Chemical composition of gaseous fuels like coal gas, natural gas, propane and more.
The gross (high) and net (low) heating values.
Emission of Nitrogen Oxides - NOx - with combustion of fuels like oil, coal, propane and more.
Common solids - like brick, cement, glass and many more - and their specific heats - in Imperial and SI units.
Coal stokers classified on basis of coal burning capacities.
