coal gasifier steam

Coal gasification power generation system

The coal gasifier is generated in a hot process which makes the solid fuel (coal or coke) be gasified, that is to say by mixing the hyperthermal solid fuel (coal or coke) with oxygen or oxygen content (steam, carbon dioxide), the gasifying agent will make effect in Oxidation and produce a type of mixed gas which consists of hydrogen, carbon monoxide and methane, etc. And it is called coal gas.

Advantages & Disadvantages of Coal Gasification

Converting coal to gas using gas solid reactions primarily featured the reaction of the carbon in coal with steam at pressures lower than 10 MPa and temperatures above 750°C. The coal gasification process would produce hydrogen, ammonia, methanol and hydrocarbons, and they were also used with steam to create synthetic natural gas (SNG).
