Saw Dust Gasification Power Plant
POWERMAX SAW DUST GASIFICATION POWER PLANT
The basic principle of POWERMAX’s Saw Dust biomass gasification power generation system(abbreviated as BGPS) is to convert wood chips,saw dust,branches,bark,forestry residues and etc. into combustible gas . It is then used as fuel in gas engine to generate electricity. Biomass gasification successfully conquers the disadvantages of wood waste 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.
Necessary Requirement of Saw Dust can be used in POWERMAX Wood Waste Gasification Power Plant:
Humdity of wood waste less than 20%. Size less than 15mm For Circulating Fluidized Bed Gasifier(CFBG series)
Humdity of wood waste less than 20%. Size less than 10-75mm For Twin-Fire Fixed-bed Gasifier(TFBG series)

POWERMAX WOOD WASTE GASIFICATION POWER PLANT PROCESS
Our biomass(wood waste) gasification process includes three steps. The First step is biomass gasification, which convert wood waste 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.
Technology Of POWERMAX Saw Dust Gasification Power Plant
The POWERMAX Saw Dust gasification power generation systems are based on a modular concept and are able to applicable for 50-20000KW wood waste biomass power station. There are two series of biomass gasification system offered by POWERMAX which ranges from 50-2000KW of power generation: CFBG (Circulating Fluidized Bed Gasifier) Series, TFBG(Twin-Fixed Bed Gasifier) Series. A series biomass generator sets from 50KW to 1000KW are developed by POWERMAX to combine with POWERMAX advanced gasification technology. These gas generator sets are using the high efficiency Siemens technology alternators, Chinese top brand medium speed gas engine(500-1000rpm),German Detuz Gas Engine(1500rpm) with advanced European engine control systems. The high performance of the POWERMAX biomass gasification plants and the later production of electricity with the gensets represents a competitive solution when compared with conventional boiler-fired system.
