Biomass gasification power generation can be realized by three ways:
a. Biomass after gasifying becomes gas fuel which is directly into the gas fired boiler to produce steam, and then drive the steam turbine for the power generation.
b. Purified clean gas from biomass is delivered to gas turbine for the combustion and electricity generation.
c. Purified clean gas is transferred directly into the internal-combustion engine to generate electricity.
According to the power generation and investment scale, the above correspondingly match along with the large-scale, medium-scale and small scale power generation.
Nowadays, the most commercially successful biomass gasification power generation technology has been widely promoted and utilized for its product feature as following: small installed capacity, flexible layout, less investment, compact structure, reliable technology, low operating costs, significant economic benefits, simple operation and maintenance, and inferior demand on the gas quality.
Biomass gasification power generation system consists of gasifier, gas fuel purification system and gas engine. It converts various wastes into high quality electricity to solve the waste pollution problems and make rational use of resources and energy.
Gasifier, also called gasification furnace or gas producer, is the device to transform the biomass material from solid state to gas fuel. Biomass materials do the incomplete combustion in the gasifier by controlling the air supply to realize the conversion of low value biomass energy from solid state to gaseity. It generates the gas fuel containing the combustible components like H2, CO, CH4, CnHm and etc, then to accomplish the biomass gasification process.
