Energy Density of Coal
The energy density of coal, i.e. its heating value, is roughly 24megajoules per kilogram. The energy density of coal can also be expressed in kilowatt-hours, the units that electricity is most…
Carbon Intensity of Coal
Commercial coal has a carbon content of at least 70%. Coal with a heating value of 6.67 kWh per kilogram as quoted above has a carbon content of roughly 80%,…
Coal Gasification
Coal gasification is the process of producing coal gas, a type of syngas–a mixture of carbon monoxide (CO) and hydrogen (H2) gas–from coal. Carbon monoxide, which is a combustible gas, was…
Clean Coal Technology
Clean coal technology is an umbrella term used to describe technologies being developed that aim to reduce the environmental impact of coal energy generation. These include chemically washing minerals and impurities…
Coal-fired Power Plant
A coal-fired power plant produces electricity, usually for public consumption, by burning coal to boil water, producing steam which drives a steam turbine which turns an electrical generator. Coal is a relatively…
Coal Power Plant Schematic Diagram
Generation of electricity in a coal-fired steam station is similar to a nuclear station. The difference is the source of heat. The burning of coal replaces fissioning, or splitting , of uranium atoms…
World’s Largest Waste-to-Energy Plant
California is now home to the world's largest biomass power plant converting landfill gas into usable natural gas. Major landfill operator Waste Management, in partnership with theLinde Group, just opened its $13.5 million facility outside…
Incineration
Incineration is a waste treatment process that involves the combustion of organic substances contained in wastematerials.Incineration and other high temperature waste treatment systems are described as "thermal treatment". Incineration of waste materials…
Waste to Energy
Waste-to-energy (WtE) or energy-from-waste (EfW) is the process of creating energy in the form of electricity or heat from the incineration of waste source. WtE is a form of energy recovery. Most WtE processes produce electricity directly…
Torrefaction of Biomass
Torrefaction of biomass can be described as a mild form of pyrolysis at temperatures typically ranging between 200-320 °C. During torrefaction the biomass properties are changed to obtain a much better fuel quality for…
