Integrated biomass solution

The COGEBIO® process allows a total or partial substitution of fossil fuels (natural gas, propane, fuel oil) by solid biomass for industrial heat production. The gasifier produces a syngas at a competitive price, compared to fossil fuels, and draws value from all types of solid biomass (clean wood chips, recycled wood, agricultural residues).

The COGEBIO® process innovation consists in combining a biomass gasifier and a specific dual-fuel burner without any syngas treatment. It is available in a 1 to 10 MW range and allows syngas or fossil fuel combustion or any mix of both.

The innovating design of COGEBIO® process brings a great flexibility with a 30 to 100% power modulation allowing for an easy tracking of power demands.

    The reactor is based on the principle of downdraft  fixed bed gasification, where the solid is converted through drying, pyrolysis, oxidation, and reduction.

  • null

    The patented dual-fuel burner is designed to burn the syngas coming directly from the gasifier at 800°C with no need for any cleanup.
    It is able to use either syngas or fossil fuels (natural gas,  propane, fuel oil), alone or as a mix.

  • null

    The smoke does not require any treatment after being generated from clean wood.

    The COGEBIO® technology can be installed with all kinds of boilers, ovens, or dryers, replacing  fossil fuels burners without changes of the existing equipment.

Applications within industries and municipalities

The COGEBIO® process is for industries and communities that wish to reduce their consumption of fossil fuels by replacing them with biomass while reducing their energy bills.

The typical application is the replacement of an existing burner by our dual-fuel burner GASFLEX® for the total or partial substitution of fossil fuel.
