COAL GASIFICATION STONETEK ENERGY

2016-12-14  Coal gasification is said to have greater efficiency than conventional coal-burning because it can effectively use the gases twice: the coal gases are first cleansed of impurities and fired in a turbine to generate electricity. Then, the exhaust heat from the gas turbine can be captured and used to generate steam for a steam turbine-generator.

Coal Gasification - an overview ScienceDirect Topics

Gasification of coal is a process in which coal is partially oxidated by air, oxygen, steam or carbon dioxide under controlled conditions to produce a fuel gas. The hot fuel gas is cooled in heat exchangers, with the production of steam, and cleaned before combustion in a gas turbine.

Underground Coal Gasification (UCG) power generation

2013-2-21  Typically, coals of low rank e.g. lignite and sub-bituminous are the easiest to gasify, hence better suited for UCG. Underground Coal Gasification offers a potential means of extracting energy from deposits, which will not be amenable to conventional mining, economically. India is endowed with vast lignite resources of around 36 billion Tonnes.

Coal Gasification - ScienceDirect

2008-1-1  5.1. Introduction. Gasification is a process that converts carbonaceous materials, such as coal, petroleum, petroleum coke, or biomass, into carbon monoxide and hydrogen (Wikipedia, 2006). The gaseous products are further processed for use as an energy source or as a material for the production of a variety of chemicals and/or liquid fuels.
