Stirling engine with integrated gas combustor
This paper discusses a Stirling engine. It comprises heat transfer stacks having a cooler, regenerator and heat exchanger stacked end-to-end with a working cylinder adjacent each of the stacks and connected therewith by a hot connecting duct, the heat exchangers including an annular cluster of circumferentially spaced tubes extending from the regenerator in a substantially axial direction to an annular manifold axially spaced from the regenerator such that at any given time during operation of the Stirling engine working fluid in the tubes is flowing in a single axial direction through the heat exchanger, a combustion chamber on an end of each of the stacks having a gas flow outlet communicating with the interior of the heat exchanger tube cluster, air inlets for each of the combustion chambers for allowing air to enter the interior of the chambers, and a nozzle within the combustion chambers for introducing a combustible fuel within the combustion chambers, whereby the combustible fuel and air combust in the combustion chambers and generate hot gases which pass between the tubes applying heat to the heat exchanger.
