COMBUSTION DEVICE

摘要

The present invention relates to a combustion device to perform post-purge operation after the stopping of combustion. The combustion device performs the stable combustion operation by effectively preventing condensation on the surface of a nozzle in a nozzle manifold. The combustion device comprises a gas burner (1) which performs combustion of a fuel gas provided from the nozzle manifold (8); a combustion fan (50); and an outside temperature detection unit (90) which detects outside temperatures. When post-purge operation for rotating a combustion fan (50) is performed after the stopping of combustion, post-purge exhaust air flow is set in accordance with the outside temperatures.
