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.
