Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system. It is produced when coal is heated strongly in the absence of air.

Coal gas, gaseous mixture—mainly hydrogen, methane, and carbon monoxide—formed by the destructive distillation (i.e., heating in the absence of air) of bituminous coal and used as a fuel. Sometimes steam is added to react with the hot coke, thus increasing the yield of gas.

Historically, coal was gasified to produce coal gas, also known as "town gas". Coal gas is combustible and was used for heating and municipal lighting, before the advent of large-scale extraction of natural gas from oil wells.

Coal gas, also known as a gaseous mixture, is a fuel made up of hydrogen, methane, and carbon monoxide produced by destructive distillation (continuous heating in the absence of air) of bituminous coal.

Apr 9, 2025 · In general, coal can be considered a hydrogen-deficient hydrocarbon with a hydrogen-to-carbon ratio near 0.8, as compared with a liquid hydrocarbons ratio near 2 (for propane, ethane, butane, and other forms of natural gas) and …

Apr 17, 2024 · Coal is an abundant fuel source that is relatively inexpensive to produce and convert to useful energy. However, producing and using coal affects the environment. Effects of coal mining. Surface mines (sometimes called strip …

Compare coal vs natural gas in terms of efficiency, cost, environmental impact, and U.S. use of each fuel for electricity generation through history.

Apr 8, 2025 · Our latest Short-Term Energy Outlook forecasts U.S. coal production to decline from an estimated 512 MMst in 2024 to 483 MMst in 2025 and 467 MMst in 2026 because of coal’s continued competition with natural gas and renewables in the electric power sector.

Coal gasification, as part of an integrated gasification combined cycle (IGCC) coal-fired power station, is used to produce syngas, a mixture of carbon monoxide (CO) and hydrogen (H 2) gas to fire gas turbines to produce electricity.

Coal gas is a gaseous mixture, mainly composed of methane, hydrogen, and carbon monoxide that are formed by the destructive distillation (it means heating in the absence of air) of bituminous coal and is also used as a fuel.
