Key Terms

Gasifier
A device that converts solid biomass into gas through thermal processes.

Example: A biomass gasifier can turn wood chips into syngas.

Syngas
A mixture of hydrogen and carbon monoxide produced from gasification.

Example: Syngas can be used to generate electricity.

Fixed Bed Gasifier
A type of gasifier where biomass is placed in a fixed position.

Example: Fixed bed gasifiers are often used for small-scale applications.

Fluidized Bed Gasifier
A gasifier where biomass is suspended in a bed of hot particles.

Example: Fluidized bed gasifiers provide uniform temperature distribution.

Entrained Flow Gasifier
A gasifier that uses high temperatures to convert feedstock into gas quickly.

Example: Entrained flow gasifiers are suitable for high-throughput operations.

Thermal Efficiency
The ratio of useful energy output to the energy input in a gasifier.

Example: Higher thermal efficiency means more energy is converted from biomass.
