Biomass Energized Electrical Power Station (BEEPS) are being established using the home grown biomass. The Biomass Gasification Technology is being used for the first two power stations. In the future, for power stations of larger sizes, the Boiler Turbine Technology will be used.
Biomass Gasification Technology
Biomass Gasification Technology is an eco-friendly alternate energy source that can help organisations gain a competitive advantage. In fact, gasification is the cleanest, most efficient combustion method known. Biomass gasification is the process of conversion of solid biomass into gaseous form. In simple terms, this uses the easily available biomass and converts it into energy.
The Process of Gasification
The process of gasification consists of partial Pyrolysis, Oxidation, and reduction under sub-stochoiomatric conditions. This generates producer gas, which contains H2, CO, CH4, CO2 and N2. This raw and hot producer gas contains particles of dust and condensable compounds, termed tar, both of which should be restricted to less than 15 ppm each, for the gas to be used in the internal combustion engine. The producer gas is cleaned and coded to ambient temperature for meeting thermal needs and power generation.
Components of the Gasifier Plant
A typical integrated biomass Gasifier plant has a biomass processor, waste heat drier, biomass gasification system, power package and effluent treatment plant. The following are the major components.
• Material handling system for conveying biomass into reactor.
• Gasifier Reactor (Stainless steel and ceramic lining inside) which generates producer gas.
• Cooling, scrubbing and cleaning system, which help to clean and cool the producer gas to ambient temperature, prior to admission to burners for thermal application or into IC engines for power generation.
• Water Treatment (water can be cooled, recycled and used after chemical treatment).
• Control room (MCC, PLC instrument panel and operating control desk).
