CO concentration based auto burning-stop device for combustion facilities

摘要

The present invention relates to an automatic combustion stop device for a combustion device based on CO concentration, and is detected by a CO sensor installed in a combustion device main body or a remote location remote from the combustion device main body and communicates with a combustion controller installed in the combustion device main body. When it is detected that the CO level corresponding to the CO concentration exceeds the warning level during the combustion stop of the combustion device, the CO warning is warned, or the CO warning is warned during the combustion of the combustion device, and then combustion is in a state where the heat amount of the combustion device is limited When it is determined that CO leakage from the device, the combustion device is automatically stopped, or when it is determined that it is not CO leakage from the combustion device, the combustion operation of the combustion device is normally performed. According to the present invention, during combustion operation of the combustion device using fuel such as gas or oil, the combustion device discharges exhaust gas that is burned due to the installation failure of the combustion device or the influence of the external environment (for example, external impact, etc.). Even if exhaust gas leakage due to the exhaustion of the exhaust pipe occurs, if the CO concentration in the exhaust gas flowing into the room exceeds the warning level, a warning of CO is warned, and when CO leakage from the combustion device is determined, the combustion device is automatically burned to stop. CO leakage from the device can prevent or eliminate the problem that frequently causes CO poisoning accidents to people or animals living indoors.
