gasifier. (Show more) coal gasification, any process of converting coal into gas for use in illuminating and heating. The first illuminating gas was manufactured from coal in England in the late 18th century by the process of carbonization or destructive distillation, heating coal in the absence of air, leaving a residue of coke as a byproduct.

Gasification is a technological process that can convert any carbonaceous (carbonbased) raw material such as coal into fuel gas, also known as synthesis gas (syngas for short). Gasification occurs in a gasifier, generally a high temperature/pressure vessel where oxygen (or air) and steam are directly contacted with the coal or other feed material causing a series of chemical reactions to ...

Gasification is one of the most important advancements that has ever occurred in energy production. Using this technology, for example, coal can be gasified into a product that has roughly half the carbon footprint of coal. On a large scale, gasification could be considered a revolutionary development, not only prolonging the life of carbonbased fuels, but making them "greener" and cleaner.

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 ...

The figure of gasification reactions and transformations illustrated the concept of coal gasification, and noted resulting composition of syngas. This can vary significantly depending on the feedstock and the gasification process involved; however typically syngas is 30 to 60% carbon monoxide (CO), 25 to 30% hydrogen (H 2), 0 to 5% methane (CH 4), 5 to 15% carbon dioxide (CO 2), plus a lesser ...
