There is a need for heat and electric power in the medium-sized wood processing industry and craft companies. The need for heat is already covered by the use of biomass residues and waste materials generated there. Due to the year-round production, a much higher fuel supply is often available and must therefore be removed in a costly, non-ecological and uneconomical manner. This overcapacity will be used, in the present project, to generate electric power by implementing thermoelectric generators (TEG) in a biomass boiler so that a contribution to the electric power demand of the company is supplied.


In order to cover the heat and electric power needs of wood processing companies, a biomass boiler (1. BImSchV) will be enhanced, which also provides electric power and goes beyond the production of heat. For this purpose, thermoelectric generators are used and a demonstration boiler is developed, constructed and measured.
