Biomass Gasification Blending with Coal-fired Power Plant for Power Generation
The Biomass Gasification Blending with Coal-fired Power Plant for Power Generation The biogas is sent into the coal-fired boiler to co-generate power at scale by taking advantage of the configuration of the large power station in a highly efficient way.
Feedstock: rice husk, straw, sawdust, bamboo scrape, etc.
Product: electricity
Technological Highlights
The efficiency of mixed-fuel power generation: 32~37% > efficiency of power generation through direct combustion of biomass: 22-27%;
The corrosion to the surface of the boiler for power station by the biomass can be avoided as it is collected before entering the boiler, thus lowering the maintenance cost;
The biogas can reach the temperature of more than 400℃, ensuring high heat efficiency of overall system, and no tar and sewage.
The biomass gasifier is independent from the coal-fired power plant, allowing no influence of the fluctuation of seasonal biomass yield on the continuous stable power generation.
