2 Gasifier types and applications 6 IEA Coal Research Coal gasification refers to the reaction of coal with air or oxygen and steam, to yield a gaseous product, that is syngas, for use directly as a fuel, or as a feed to synthesise other gaseous or liquid fuels or chemicals. Gasification is in fact, an incomplete combustion of coal. Although ...

Introduction. The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a pre-determined size in order to increase the surface area of the coal.. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.

This report contains the results of a 16 month study to examine the problem of pulverizer outages and to identify root cause failure modes for the major mill types currently in service. A data base of 469 pulverizers, the majority larger than 40 tons/hr coal capacity, was compiled by surveying the utilities with coal fired boilers in this country.

Coal gasification is an established technology for producing syngas (CO + H 2), which can increase the production of hydrogen via a water-gas conversion reaction (H 2 O + CO ↔ H 2 + CO 2) [11, 12]. This can enable the production of high concentration of hydrogen through simultaneous CO 2 capture [13, 14].

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 …
