Power generation by using biomass gas from rice husk, wood chips ,saw dust, coconut husk, bagasse, straw and crop stalks can not only save electricity expenses in the production cost for rice mills and timber processing mills, but also get benefits from selling surplus electric power to the power grid. Our biomass gasification equipment gets high conversion efficiency, by taking rice husk as an example, each kwh power generation consumes only 1.6~1.8kg rice husk, the unit fuel consumption will be still lower by using wood chips or crop stalks as fuel. Water for gas cleaning and cooling can be used in a circulating way without environmental pollution after it’s treated through water treatment facilities such as sediment pond, and a little of making-up water required. The water pond for each unit of 200kw plant only covers about 50m2 .The engines and generator, electrical equipments should be put indoors, other equipments could be put outdoors. The construction area for each 200kw generator set is approximate 40~50m2. The self-consumption power rate of full set of equipment is only 5~8% of the generated power. Therefore, such a project is an ideal one with significant benefits for the area where there is a lot of discarded biomass resources but is short of electric power supply or with higher electricity expense. In general, the investment for major equipment can be recovered from power generation benefits within first two years. The equipment can be safe and reliable operated with operational technology that’s easy to be mastered by workers, and the maintenance and repair work is similar to ordinary diesel generators.

Biomass Gasification System series Specifications

Note:

Main components and caloricity of biomass gas are subject to characteristic of biomass fuel and gasification method.

The caloricity of biomass gasification gas is normally 1100-1500kcal/Nm3.(4.6~6.3MJ/Nm3)

For example, main component of rice husk gasified gas are as follows:

(The caloricity is:1393kcal/ m3 (5.83 MJ/Nm3)

When operation temperature is 800°C, the tar production ratio in fluid bed gasification furnace(patented product of Fengyu Group) is about 2.5%. Tar content after treatment is less than 50mg/m3, through strict cleaning and thermal cracking, the dust & tar content of biomass gas are very tiny, which can meet the requirement for the internal-combustion engines normal operation.
