ABSTRACT:
There is provided a combustion safety apparatus where the main burner has a combustion detecting element such as an oxygen concentration cell element, and the element is arranged so that one electrode thereof is always heated by a flame of a standing burner and into an oxygen lack condition while the other electrode is heated by the main burner. When the main burner is in its complete combustion condition, there is a difference in oxygen concentration between the two electrodes and thereby there is generated an output at the element. On the other hand, when the main burner is in its incomplete combustion condition, the difference in oxygen concentration therebetween is decreased and thereby the output is lowered. In addition there is provided a safety device such as a gas safety valve or the like. The same is arranged to be controlled in operation by the output directly or indirectly; the element is formed into a long plate disposed to extend along nearly at a right angle to the direction of the flame of the standing burner.
