<p>PROBLEM TO BE SOLVED: To provide a combustion device determining whether accidental fire is caused by outside wind, and capable of performing re-ignition of a burner as needed.SOLUTION: In a case where occurrence of accidental fire at a burner 4 is detected, it is detected whether a differential pressure fluctuation phenomenon in wind blowing, where the differential pressure of combustion air and combustion exhaust gas is increased or decreased by the fact that outside wind acts to one or both of an air inlet 21 and an air outlet 22, occurs or not in a predetermined period right before the case. When the occurrence of the differential pressure fluctuation phenomenon in wind blowing is detected, the burner 4 is ignited again, and when the occurrence of the differential pressure fluctuation phenomenon in wind blowing is not detected, the burner 4 is caused to keep an extinction state.</p> |
