The basic principle of biomass gasification system(abbreviated as BGPS) is to convert Agriculture and forestry products and wood processing remains (including rick husks, wood powder, branches, offcuts, corn straws, rice straws, wheat straws, cotton straws, fruit shells, coconut shells, palm shells, bagasse, corncobs,) into combustible gas . It is then used as fuel in gas engine to generate electricity. Biomass gasification successfully conquers the disadvantages of biomass, such as low flammability and wide diversity. Biomass gasification system is characteristic of small land requirement and environment friendly. It’s one of the most effective way of biomass utilization.              

      Comparing with other renewable power generating system, BGPS is characteristic of:

1). Flexibility. Gas engine, gas turbine and even waste heat recovery boiler may be used considering various power plant capacity requirements. It ensures high power generating efficiency. Different capacities of biomass power generation plant can be designed with various types of BGPS system.

2). Clean technology. Biomass, as one kind of renewable energy, may reduce the emission of carbon dioxide, sulfur dioxide causing from fossil fuel. Nitrogen oxides emission is very limited in our biomass gasification power generating system because of low temperature (700℃~900℃).

3). Economic. BGPS is capacity flexible. Even small size biomass power plant is also profitable. Simple process and less land requirements make biomass gasification power plant more economic comparing with other renewable energy. Generally speaking, biomass gasification power generating is the most economic technology in renewable power generating plant, the cost of which is nearly the same as small-size conventional power plant.
