Gasification is a process that converts organic or fossil based carbonaceous materials into carbon monoxide, hydrogen and carbon dioxide. This is achieved by reacting the material at
high temperatures (>700 °C), without combustion, with a controlled amount of oxygen and steam. The resulting gas mixture is called syngas and is itself a fuel. The power derived from gasification and combustion of the resultant gas is considered to be a source of renewable energy because the gasified compounds were obtained from biomass.


Gasification system is based on a fixed-bed gasifier, or as a more sophisticated system, on using fluidized-bed technology.

The produced syngas is subsequently filtered, cooled and eventually used as a fuel in an internal combustion engine, which is connected to a generator.

Berman bes, through its expertise and experience, offers a wide range of supplies relating to a power plant in all stages of energy production from biomass gasification.

BERMAN’s fluid-bed biomass gasifier (patented product of B&D Group) gets high conversion efficiency. Taking mixed wood chip as an example, each KWH power generation consumes only 1.2~1.3kg of mixed wood chips, and this  fuel consumption unit can be even lower by using hard wood chips or crop stalks as fuel. When operation temperature is 800°C, the tar production ratio in fluid bed gasification furnace is about 2.5%. Tar content after decoking treatment is less than 50mg/Nm3. Through strict cleaning and thermal cracking, the dust & tar content of biomass gas gets very tiny, in order to meet the requirements of the internal-combustion engine and steam turbine normal operation.


Power generation by using biomass gas from wood chips, saw dust, husks, bagasse, crop stalks and olive pomace can not only save electricity expenses in the production cost for mills, timber processing mills, farm and plantations etc., but can also get benefits from selling surplus electric power to the power grid.

The engines and generator electrical equipments should be placed indoors. Other equipment 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 ideal and shows significant benefits for an area that has plenty of biomass resources but is short of electric power supply or has higher electricity rates.

In general, investment in major equipment can be returned from power generation benefits within the first two years. The equipment is safe and reliable, its operational technology can be easily mastered by workers, and the maintenance and repair work is similar to ordinary diesel generators.
