2. On Premixed Gas Fuelled Stirling Engine Combustors with Combustion Gas Recirculation
Abstract : 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. READ MORE
