A Gasification Technology in Biomass and Coal Based Integrated Gasification Combined Cycle Power Generation System: A Review

Electricity generation through Non-renewable energy i.e;coal–thermal route is one of the most responsible for environment pollution through greenhouse gas emission, which has given rise to issue of climate change risk. Coal combustion results large pollution and affect the environment. The harmful gases affect the atmosphere and act opposite to the nature. Today India is more concentrated towards non-conventional energy sources. Currently, in India 20.1% of power is generated through non-conventional i.e.; renewable energy sources. And if we want an IGCC power plant for remote location then there be a requirement of small scale power plant. For small scale IGCC power plant there may have the installation of downdraft gasifer because Downdraft gasifier is very attractive for biomass gasification due to its easy fabrication and operation, and also due to low tar content in producer gas. Finally, a brief review of the literature on gasification of coal/biomass and also reviews on the fluidized bed technology to discuss the main process parameters and their influence on the product composition, quality of the fuel gas and the operability of the gasifier as well as blends in bubbling/circulating fluidized bed gasifiers has also been presented.
