  • Publication number: 20150152809
    Abstract: An annular venturi burner assembly and Stirling engine. The annular venturi burner injects fuel into combustion air flowing axial through an port with an annular cross section. The fuel enters the annular cross-section from the outside diameter. The flow of air through the annular section creates suction that draws the fuel through the ports. An venturi bushing directs the flow of fuel to provides improved and more uniform mixing of fuel and air.
