  3. Coal gasification - Wikipedia

    en.wikipedia.org/wiki/Coal_gasification

    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. In current practice, large-scale coal gasification installations are primarily for electricity generation (both in conventional thermal power stations and molten carbonate fuel cell power stations ...

  4. Integrated gasification combined cycle - Wikipedia

    en.wikipedia.org/wiki/Integrated_gasification...

    In particular, coal contains more CO 2 per BTU than oil or natural gas and is responsible for 43% of CO 2 emissions from fuel combustion. Thus, the lower emissions that IGCC technology allows through gasification and pre-combustion carbon capture is discussed as a way to addressing aforementioned concerns. [1]

  5. Underground coal gasification - Wikipedia

    en.wikipedia.org/wiki/Underground_coal_gasification

    Underground coal gasification converts coal to gas while still in the coal seam (in-situ). Gas is produced and extracted through wells drilled into the unmined coal seam. Injection wells are used to supply the oxidants (air, oxygen) and steam to ignite and fuel the underground combustion process. Separate production wells are used to bring the ...

  6. Pulverized coal-fired boiler - Wikipedia

    en.wikipedia.org/wiki/Pulverized_coal-fired_boiler

    The concept of burning coal that has been pulverized into a fine powder stems from the belief that if the coal is made fine enough, it will burn almost as easily and efficiently as a gas. The feeding rate of the pulverized coal is controlled by computers, and is varied according to the boiler demand and the amount of air available for drying ...

    65–97% for gas-fired heating; 80–89% for oil-fired and; 45–60% for coal-fired heating. [26] Oil storage tanks, especially underground storage tanks, can also impact the environment. Even if a building's heating system was converted from oil long ago, oil may still be impacting the environment by contaminating soil and groundwater.

    en.wikipedia.org/wiki/Coal_gas

    In the United Kingdom the discovery of large reserves of natural gas, or sea gas as it was known colloquially, in the Southern North Sea off the coasts of Norfolk and Yorkshire in 1965 [8] [9] led to the expensive conversion or replacement of most of Britain's gas cookers and gas heaters, from the late 1960s onwards, the process being completed ...
