N2 - The main objective in the research described in this thesis was to design and test the use of lean premixed combustion using combustion gas recirculation for gas fuelled Stirling engine combustors. A system using a flame-arrester type of flame-holder to stabilize the flame and an ejector system for the recirculation of combustion gas was designed and tested in the laboratory. The impact of changes in different parameters of the ejector system was examined. Different combinations of recirculation rate and air/fuel ratio were examined regarding their impact on emissions and flame stability. The laboratory combustion system was then adapted to commercial combustors. A propane combustion system for a hybrid sodium heat pipe solar receiver for the SOLO 161 Stirling engine was designed, built and field-tested with good results. Later a natural gas combustor for a SOLO 161 combined heat and power Stirling engine unit was designed, built and field-tested with good results. The combustor has currently run about 2500 hours in field test. At lambda 1.4 the NOX emissions are about 15 ppm, with no emissions of unburnt hydrocarbons (HC). Tests have been made with a catalytically coated solar receiver for the V160 Stirling engine with the objective to use catalytic combustion on the heater surface to supply heat to the Stirling cycle. The results were promising and it was possible to heat the receiver to operating temperature and run the engine for shorter times. However, further research is needed before this type of heater can be used.
