coal gasification systems

Gasifiers - an overview | ScienceDirect Topics

Underground coal gasification (UCG) takes a much different approach. In UCG, un-mined coal seams are reacted underground, with insufficient oxygen for complete combustion, to create syngas. Figure 5.1 shows a conceptual drawing of UCG. An oxidant, usually air, flows through an injection well and into a cavity in a coal seam.

Gasification - Clean Coal

Gasification power systems are able to achieve high power efficiencies because they use both a combustion and steam turbine in what is known as a "combined cycle." "Higher efficiencies mean that less fuel is used to generate the rated power, resulting in better economics (which can mean lower costs to ratepayers) and the formation of fewer ...

5.1. Gasification Introduction | netl.doe.gov

Gasification is a technological process that can convert any carbonaceous (carbon-based) 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 ...
