の燃焼全停止する。Operation The present invention has the above-described configuration, so that even though the solenoid valves that stop the supply of fuel to each combustion section are closed, fuel is supplied to the combustion sections due to dirt or seal failure in the solenoid valves. If combustion continues, it is detected by the combustion detector and the full combustion signal is output to the abnormal combustion detection section. Since the abnormal combustion detection section receives the closing signal of the solenoid valve, it determines that there is an abnormal combustion and outputs a full operation stop signal to the control section, which receives the signal and closes all the solenoid valves. Closes, and combustion of multiple combustion sections is completely stopped.

利（財）部８に出力する。9 is an abnormal combustion detection section, which includes a combustion detector 6. Input the combustion signal from the combustion detector 6 and the open/close signals of the solenoid valves 3 and 4, and check if the combustion signal from the combustion detector 6 is input even though the solenoid valve 3 is closed, or if the solenoid valve 4 is closed. When a combustion signal from the combustion detector 7 is input to the engine, it is determined that there is abnormal combustion, and an operation stop signal is output to the interest rate (finance) section 8.

２に燃料が供給されなくなり、燃焼が停止する。Next, the entire operation will be explained. For example, when only the combustion section 1 is burning, the solenoid valves 3 and 6 are open and the solenoid valve 4 is closed, but the combustion section
When fuel is supplied to and burns, it is detected by the combustion detector 7 and a full combustion signal is output to the abnormal combustion detection section 9. Then, since a combustion signal is input from the combustion detector 7 even though a closing signal for the electromagnetic valve 4 is input from the control section 8, it is determined that abnormal combustion has occurred, and a full operation stop signal is output to the control section 8. Control unit 8
receives the operation stop signal and closes the solenoid valve 6, so that fuel is no longer supplied to the combustion section 2 and combustion is stopped.
