vapour (H2O)—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas". Coal gas is combustible...

Coal mining is the process of extracting coal from the ground or from a mine. Coal is valued for its energy content and since the 1880s has been widely...

life-cycle greenhouse gas (GHG) emissions from shale gas are similar to those of conventional natural gas, and are much less than those from coal, usually about...

posterity. So-called "gas works" produced coke by heating coal in enclosed chambers. The flammable gas that was given off was stored in gas holders, to be used...

Coal tar is a thick dark liquid which is a by-product of the production of coke and coal gas from coal. It is a type of creosote. It has both medical and...

early 1800s, natural gas became known as "natural" to distinguish it from the dominant gas fuel at the time, coal gas. Unlike coal gas, which is manufactured...

that remove sulfur and oxides from power plant flue gas streams. FGD comprises 24 percent of all coal combustion waste. Residues vary, but the most common...

as natural gas, fuel oil and coal. The data were obtained by stoichiometric calculations. The total amount of wet flue gas generated by coal combustion...

A fossil fuel is a hydrocarbon-containing material such as coal, oil, and natural gas, formed naturally in the Earth's crust from the remains of dead plants...

Coalbed methane (CBM or coal-bed methane), coalbed gas, or coal seam gas (CSG) is a form of natural gas extracted from coal beds. In recent decades it...

Coal liquefaction is a process of converting coal into liquid hydrocarbons: liquid fuels and petrochemicals. This process is often known as "Coal to X"...

gases" (also known as "manufactured fuel gas", "manufactured gas" or simply "gas") were made by gasification of combustible materials, usually coal,...

taken from coal or petroleum. The term was in use by the late 18th century for oil produced as a by-product of the production of coal gas and coal tar. In...

fuel gases include: Coal gas, obtained from pyrolysis of coal Water gas, largely obsolete, obtained by passing steam over hot coke Producer gas, largely...

methane gas which on release can generate a spark of static electricity to ignite the gas and start a coal explosion and fire. The same gas static is...

A gas holder or gasholder, also known as a gasometer, is a large container in which natural gas or town gas (coal gas or formerly also water gas) is stored...

Gas carbon is a carbon that is obtained when the destructive distillation of coal is done or when petroleum products are heated at high temperatures in...

pollution, coal burning produces hundreds of millions of tons of solid waste products annually, including fly ash, bottom ash, and flue-gas desulfurization...

operated on hydrogen gas. Water gas has a lower heat of combustion than coal gas, so the calorific value was often boosted by passing the gas through a heated...

Indonesia's total energy supply (TES) comprised 30.3% coal, 28.9% oil, and 14.4% natural gas. Renewable energy sources also added to the mix, with biofuels...
