Development of a biomass-fuelled gasifier/stirling generator for developing countries

Objective



Project JOU2-CT92-0160 is developing an efficient, cheap, reliable, 10 kWe biomassfuelled Gasifier/Stirling generator for developing countries. Recent Stirling research has focussed on high speed, high power/weight ratio engines using very high pressure helium as charge gas, which are too expensive and/or unreliable for commercial use.
In contrast, this project is developing a low speed engine with lower pressure air or nitrogen as charge gas.
This, together with radical design innovations, overcomes sealing problems, improves performance, reduces component costs, and will enable the modern Stirling engine to be commercial for the fist time.
Innovations in the gasifier overcome past problems in gas cleaning.
The present proposal extends the project to three Eastern European countries Romania, Hungary and Slovakia - which have isolated and mountainous areas with energy supply problems, and which suffer power shortages as a result of low grade coal supply problems and the lack of foreign exchange for energy imports; widespread use of lowgrade coal is imposing significant environmental damage.
Thus there is an urgent need for alternative sources of power. All three have supplies of biomass residues, much of which is not used by households or rural industries; an efficient and costeffective means is needed to convert them and future energy crops into power, at scales which match the decentralised nature of the fuel.
There is no experience of Stirling engines for power production, and this project will introduce an R and D programme based on the SES 13 kW engine, with technology exchange on gasifiers.
It will add field experience, on new fuels, to the original project, which will benefit from existing gasifier design experience in Romania.
There is also considerable experience, particularly in Romania, in the use of the Stirling cycle in cryogenics and refrigeration; the project will, by introducing trials of the SES engine, foster its development as a power source in these applications, and for heat pumps.
