Claims

[Scope of utility model registration request]

The pressure inside the inner shell is negative or slightly positive during normal combustion, and positive when the fins are clogged.An exhaust overflow duct that communicates with the outside atmosphere is fixed at a predetermined position in the inner shell, and a thermocouple is installed in the exhaust overflow duct. A secondary thermocouple is installed with the hot junction facing the cold junction fixed to the water supply pipe wrapped around the outer circumferential surface of the inner shell, and the primary thermocouple and fuel supply are heated by the pilot burner flame to generate a thermoelectromotive force. The secondary thermocouple is interposed and connected to a circuit consisting of an electromagnetic coil of an electromagnetic safety valve that opens and closes a passage so that its thermoelectromotive force is in the opposite direction to the thermoelectromotive force of the primary thermocouple. Incomplete combustion prevention device for combustor.
