  • Stirling engine and method of removing impurities in a heat-transfer tube group in a power device or a power-generating device which uses a stirling engine
    Patent number: 9097206
    Abstract: The present invention provides a Stirling engine capable of effectively recovering heat from exhaust gas flowing through a flue 42, and capable of connecting a heating portion 10 and a regeneration portion 5 with each other through an operation gas tube without providing a flow passage separating portion 110, and as the removing mode, number of revolutions of the Stirling engine is reduced, an operation of the Stirling engine is stopped, an amount of generated electricity at the Stirling engine is reduced, or the Stirling engine is reversely rotated.
    Type: Grant

  • Stirling engine
    Patent number: 8899037
    Abstract: The present invention provides a Stirling engine capable of effectively recovering heat from exhaust gas flowing through a flue, and connecting a heating portion 10 and a regeneration portion 5 with each other through an operation gas tube without providing a flow passage separating portion 110, and the heating portion 10 includes a heating portion head 10a and a heat-transfer tube group, the heating portion head 10a includes first through holes 30R and second through holes 30S, the first through holes 30R are formed closer to a center region of the heating portion head 10a as compared with the second through holes 30S, one ends of U-shaped tubes are mounted in the first through holes 30R and the other ends of them are mounted in the second through holes 30S, and parallel exhaust gas flow passages is formed between the U-shaped tubes.
