The basic principle of POWERMAX’s biomass gasifcation system (abbreviated as BGPS) is to convert agriculture and forestry products and wood processing remains (including rice husk, wood powder, branches, offcuts, cron straws, rice straws, wheat straws, cotton straws, fruit shells, coconut shells, palm shells, bagasse, corncobs and etc.) into combustible gas.
lt 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. lt’s one of the most effective way of biomass utilization.
The First step is biomass gasification, which converts biomass into syngas.
●The Second step is syngas purification. The produced 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.
A series of biomass generator sets from 50kW to 1200kW are developed by POWERMAX and are combined with POWERMAX advanced gasification technology.
These gas generator sets are using the high efficency Siemens technology alternators, Chinese top brand medium speed gas engine (500-1500rmp) with advanced European engine control systems. The high performance of the POWERMAX biomass gasification plants and the electricity generating from the gensets represents a competitive solution when compared with conventional boiler-fired system.
Comparing with other renewable power generating system, POWERMAX-BGPS is characteristic of:
●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 POWERMAX-BGPS system.
Clean technology
Biomass, as one kind of renewable energy, may reduce the emission of carbon dioxide causing from fossil fuel. Nitrogen oxides emission is very limited in our biomass gasification power generating system because of low temperature(700℃ - 1200℃)。
Economical
POWERMAX-BGPS is capacity flexible. Even small size biomass power plant is also profitable process and less land requirements, which means biomass gasification power plant is more economical comparing with other renewable energy. Generally speaking, biomass gasification power generating is the most economical tecnology in renewable power generating plant, the cost of which is nearly the same as small-size conventional power plant.
