Summary

The first hermetic Stirling cycle engine to produce combined heat and power was built and tested by professor Carlqvist in Sweden. This was a kinetic machine. A further development in the USA at present concentrates on dual fuel solar and natural gas free piston Stirling engines now undergoing trials. A UK company has designed a packaged unit based on the Carlqvist engine. This uses a gas supply to power the hot end of the Stirling cylinder while the cool end produces 8 kilowatts of hot water at 70 deg C. The kinetic movement is harnessed to a generator producing a 3-kilowatt single-phase electrical supply. Overall efficiency is claimed at above 90%. Manufacturing costs, operating costs and a maintenance system have been calculated. D.W.H.
