Biomass gasification is a process that converts biomass materials, such as wood chips, agricultural residues, or energy crops, into a combustible gas known as syngas (synthetic gas). The syngas is primarily composed of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), methane (CH4), and other trace gases.

The gasification process involves exposing the biomass feedstock to high temperatures (typically between 700°C and 1,200°C) in a controlled oxygen-starved environment. The absence of oxygen prevents the biomass from burning completely and instead promotes the partial combustion or thermochemical conversion of the organic matter.

Main Process

The internal combustion engine, external combustion engine, steam turbine, and ORC system power generation processes make up the bulk of Kerone’s biomass gasification power generation system. In order to ensure that the combustible gas entering the engine is clean and can extend the service life and frequency of maintenance of the engine, it is necessary to perform a gas purification before entering the generator because biomass gas is a mixed gas that contains mixed impurities like wood tar, wood vinegar and a small amount of ash.

Biomass Gasification Main Types

Kerone uses a fixed bed suction form of biomass gasification. This system has the benefits of steady gas production, reliable operation, and continuity. It is frequently applied in industrial settings. This system’s gasification temperature ranges from 750 to 850 degrees Celsius. CO, CH4, H2, and N2 are the flammable mixed gases created, whereas CH4 and H2 are the other inflammable gas. The gasification efficiency is greater than 75%, and a yield of 3-5% biochar is possible. If there are particular requirements, the biochar production ratio can be adjusted once more.
