PURPOSE:To improve safety, thermal output and thermal efficiency by arranging an radiation member having specific heat resistance while surrounding heater tube group for heating the operating gas through combustion heat from a combuster thereby uniforming the temperature distribution of heater tube group. CONSTITUTION:Upon start of Stirling engine 3 under such state where combustion is performed continuously in combustion chamber 1 while cooling is performed continuously by a cooler 7, the operating gas will form Stirling cycle to produce power. A gas feed piston 8 will feed operating gas to a heater tube 4 and cooling tube 7 in order to heat/cool alternatively. Here, a radiation body 11 made of metal mesh having heat resistance higher than the heater tube temperature is arranged while surrounding the heater tube 4 and supported by a supporting ring 12. Consequently, the metal mesh 11 is heated by combustion gas flowing out between the heater tubes 4 to radiate heat. Consequently, the rear face of heater tube 4 is heated to uniform the temperature distribution of heater tube 4. |
