发明名称 OPEN TYPE COMBUSTION DEVICE
摘要 PROBLEM TO BE SOLVED: To provide an open type combustion device capable of further enhancing safety to at least one of fuel leakage and imperfect combustion.SOLUTION: An open type combustion device is configured to execute ignition processing in which a control means 4 operates a blower means 5 and operates an ignition means 2, and a fuel blocking/continuing means V is switched into a fuel supply condition, when start of operation is commanded by an operation commanding means 20. When the concentration corresponding signals of gas sensors 3, 17 becomes a signal having gas concenration higher than a set value for detecting abnormal conditions for detecting fuel leakage or incomplete combustion to detect the fuel leakage or the incomplete combustion, the device is also configured to prohibit the combustion start of a burner 1, without accepting the command of starting operation by the operation commanding means 20, till the gas concentration becomes a lower signal than the set value for canceling standby in which the concentration corresponding signals of the gas sensors 3, 17 are set to the concentration corresponding signal in which a gas concentration is equal to or lower than a set value for detecting abnormal conditions, after switching the fuel blocking/continuing means V into the supply stop condition.
