Abstract
An efficient utilisation of biomass for energy with a minimum of environmental impact can be obtained, when biomass is used for small-scale combined heat & power (CHP) production in villages close to biomass production sites as well as in the wood processing industries.
The main objective of this proposal is to develop a small-scale biomass fired CHP plant based on a 70-100 kWe hermetic Stirling engine and to erect a pilot plant where comprehensive test runs will be performed with solid biomass fuels. This new development will be based on the experiences already obtained with a 30 kWe Stirling engine that has been in operation for more than 700 hours. The further technological development is essential in order to extend the area of application & cover the large market potential of biomass CHP plants.
The aim of the project is to develop a technology with high overall electric (>20%) efficiency and low operating and maintenance requirements to achieve production costs for electricity of about 0.05 Eur/Kwh corresponding to investment costs of 1,000 Eur/kWe. With this new technology a significant reduction of CO2 emissions compared to established technologies for heat & power production will be reached.
Consortium
In order to develop the Stirling engine and the biomass combustion system, the project combines the scientific skills of two universities involved with the knowledge and experience of the companies involved. Technical University of Denmark is responsible for the development of the Stirling engine in co-operation with the company I.B. Bruun & Son, Denmark. BIOS, Austria, is responsible for the development and optimisation of the biomass combustion in co-operation with MAWERA, Austria, who is also responsible for the erection and testing of the biomass combustion system. The University of Bradford is responsible for implementing new optimisation techniques, which are used for optimising the Stirling engine and the combustion system. E.ON. Energie is responsible for the technoeconomic analysis of the overall CHP technology.
