Beneficiation of noncoking coal is gaining ground in India. It not only reduces the volume of inert content to be transported to the power plant and also lowers the wear in the boiler houses. For special applications such as the fuel for integrated gasification combined cycle plant (IGCC), the ash content in the coal should preferably be below 15 %. Indian coals are characterized by high ...

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 of biomass for power generation has only been proven in small scales. Most biomass gasification applications demonstrated to date for electric power have power output less than 10 MW (Heschel and Klose 1995). Biomass is also being investigated for cogasification with coal to reduce fossilbased CO 2 emissions.
