Abstract:
Biomass is one pillar in renewable energy utilization. In all applications – heat, power and fuel – high conversion efficiency is necessary. Decentralised electricity production in combination with and based on biomass still finds some difficulties in real applications. There is also a deficit of proven technologies, especially in small-scale gasification and use of producer gas in internal combustion engines. One concept favoured in a recent project is the connection of a wood chip furnace with a Stirling engine. Because the direct exposure of the Stirling head causes numerous problems, the solution is sought in designing an indirect heat transfer system. The main challenge is the temperature level, which should be reached for high electrical efficiencies. Temperatures above 1000°C at the biomass combustion side are needed for an efficient heat transfer at some 850°C at the Stirling engine like our measurements shows. Measurements on both installations have been conducted and analysed. After this, the design phase is started. However, no final choice on the design has been taken.
