Abstract
A safety device for an oil burner is disclosed which is capable of detecting abnormal combustion which forms an excessively decreased flame, for example, sufficient to produce incomplete combustion gas to operate a fire-extinguishing device of the oil burner. The safety device includes an abnormal combustion sensing and actuation mechanism which is adapted to receive heat rays from the oil burner to detect the abnormal combustion and a starting member selectively actuated by the mechanism to operate the fire-extinguishing device when the mechanism detects the abnormal combustion.
