3 MW biomass gasification power generation system

    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.              

      Our biomass gasification process includes three steps. The First step is biomass gasification, which convert biomass into syngas. The Second step is syngas purification. The producer gas coming from gasifier usually contains contaminants including dust, coke, tar and etc. The contaminants will be removed by the purification system to ensure normal operation of gas engine. The Third step is power generating in gas engine. The high temperature exhaust gas may be reused by waste heat boiler to generate steam or hot water for civil or industrial use). Steam turbine may also be considered to make a gas-steam combined cycle power plant, which will increase the total efficiency.Modulization is adopted in BGPS. BGPS is applicable for the biomass power plant ranging from 200KW to30000KW. 500rpm~600rpm gas engine and Siemens generator are chosen in our gas generator sets (400KW, 500KW, 800KW, 1000KW, 1200KW). Fix bed gasification system or fluidized bed gasification system may be chosen according to different feedstock characteristics in BGPS (single system capacity ranging from 100KW to 2MW).                                                      

      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.
