While combustion is stopped, the first solenoid valve is opened and the second solenoid valve is closed, and all fuel sent to the burner is sent to the recirculation fuel switching valve through the circulation pipe. In the case of low combustion, the first solenoid valve is closed and the drip-proof valve is opened.
The fuel sent from the supply fuel switching valve to the circulation pipe is sent from the drip-proof valve to the low combustion side nozzle and is spray-combusted. In the case of high combustion, by opening the second solenoid valve from the low combustion state, the fuel sent from the supply fuel switching valve to the burner branches to the circulation pipe and the high combustion side pipe, and the low combustion side and the high combustion side Spray combustion from nozzle.
