3. generation CHP biomass gasification
The purpose of the project is to develop a concept based on gasification of biomass, taking advantage of
the combustion engines high efficiency and the reliability and robustness of the updraft gasifier. This is
achived by optimising the gas cleaning and the operation parameters for the engine, thereby adapting to
the operation of the gasifier.
The project aims to develop cogeneration based on biomass gasification in an updraft gasifier. The current
status for plants based on updraft gasifiers can deliver an electrical efficiency of approx. 25%, but there are
significant challenges and additional costs associated with the treatment of wastewater from the gas
cleaning process.
The project aims to optimize the interaction between the gasification plant and the combustion engine,
thereby minimizing construction costs of the wastewater treatment facility and minimizing the handling of
residues.
The gasification plant is based on internal development work performed in the partnership of 1rgi and
Gasification DK and a complete measuring program supported by the Environment Agency's development
program, as well as the know-how gathered in partnership 1rgi and Gasification DK.
Regarding the combustion engine, the project is rooted in Frichs, who has many yers experioence in the
construction and installation of combustion engines and CHP-plants, and also has an engine type that is
suited for the planned modifications and operation.
The work performed in the project will pave the way for a demonstration plant based on the
development and knowledge gathered during this project phase.
The project aims to develop cogeneration based on biomass gasification in an up-draft gasifier. The current status for plants based on updraft gasifiers can deliver an electrical efficiency of approx. 25%, but there are significant challenges and addi-tional costs associated with the treatment of wastewater from the gas cleaning pro-cess. By optimizing the interaction between the gasification plant and the combus-tion engine, and thereby minimizing construction costs of the wastewater treatment facility, CAPEX will be reduced.
The project demonstrated the methods necessary, both in terms of reducing the need for waste water treatment and the use of the tar residue from the gas clean-ing as an engine fuel.
