The gasification technology that has been developed by TAIM WESER is based on a Down-Draft gasification vessel with a descending parallel flow, which is characterised by the low tar content in the gas product.
The technology applied is the gasification of diverse agriforest and wood waste in a poor oxygen atmosphere using air as a gasification agent. The main characteristics of this type of fuel are humidity (10-15%) and grain size (0,2-10 cm).
The biomass feed into the gasifier is heated in the poor oxygen atmosphere, to avoid combustion, producing a gas which, after various processes of conditioning, feeds a gas engine connected to a generator.
The thermal energy produced can be used either for drying the biomass, if this reaches the plant with a higher humidity than the optimum for operation (10-15%),as well as other applications which TAIM WESER can develop as per client requirements. Within the possible applications we highlight the following:
- Community heating for public buildings or residential communities.
- Drying processes (alfalfa, painting furnaces)
- Heating and cooling of warehouses.
