ABSTRACT:
A double-combustor type pulsating combustion apparatus has a pair of pulsating combustors. Fuel-supplying valves are respectively provided in fuel-supplying pipes connected to the upstream sides of combustion chambers of the pair of pulsating combustors. A combustion control unit controls to stop only one pulsating combustor and to operate only the other pulsating combustor by closing one fuel-supplying valve corresponding to one pulsating combustor in a combustion range of 1/2 or less of the maximum combustion amount of the double-combustor type pulsating combustion apparatus. The combustion control unit further controls to operate both the pulsating combustors by opening both the fuel-supplying valves in a combustion range exceeding 1/2 of the maximum combustion amount.
