Updraft Gasifiers These type of gasifiers are one of the simplest and most common types of gasifier for biomass. With updraft gasification, the fuel is supplied at the top and the air at the bottom so that fuel moves against the air flow. Downdraft Gasifiers The downdraft design is essentially the same as the updraft design except that ...

Coal gasification is a process in which coal is converted to a lowgrade gas; it can be regarded in many ways as fuelrich combustion. Oxygenblown coal gasifiers operate at overall equivalence ratios (fuel to oxidizer ratio normalized by fuel to oxidizer ratio required to fully oxidize fuel) greater than two. Commercial or nearcommercial ...

In industrial chemistry, coal gasification is the process of producing syngas —a mixture consisting primarily of carbon monoxide (CO), hydrogen ( H2 ), carbon dioxide ( CO2 ), methane ( CH4 ), and water vapour ( H2O )—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas".

Coal gasification is recognized as the core technology of clean coal utilization that exhibits significant advantages in hydrogenrich syngas production and CO2 emission reduction. This review briefly discusses the recent research progress on various coal gasification techniques, including conventional coal gasification (fixed bed, fluidized bed, and entrained bed gasification) and relatively ...

Fluidizedbed gasifiers suspend feedstock particles in an oxygenrich gas so the resulting bed within the gasifier acts as a fluid. These gasifiers employ backmixing, and efficiently mix feed coal particles with coal particles already undergoing gasification. To sustain fluidization, or suspension of coal particles within the gasifier, coal of ...

Coal gasification wastewater (CGWW) is a typical toxic and refractory industrial wastewater. Here, a novel phenol and ammonia recovery process (IPE) was employed for CGWW pretreatment, and the coupled system assemble by the IPE process with A 2 /O system (IPEA 2 /O) were operated to enhance the treatment performance of CGWW. The results showed that the IPE pretreated effluent had a higher ...

Underground coal gasification (UCG) is an industrial process which converts coal into product gas. UCG is an insitu gasification process, carried out in nonmined coal seams using injection of oxidants and steam. The product gas is brought to the surface through production wells drilled from the surface. The predominant product gases are methane, hydrogen, carbon monoxide and carbon dioxide.
