ABSTRACT:
The present invention discloses a gas combustion device with a safety device including a combustible gas sensor which consists of an oxygen concentration cell comprising a calcined solid ion conductive electrolyte material and porous electrodes attached to both the major surfaces of the electrolyte material. The safety valve is operated in response to both outputs from the combustible gas sensor and from a pilot burner sensor including a thermocouple or the like. When the carbon monoxide content is increased, the safety valve is automatically closed, thereby interrupting the supply of gas and consequently preventing carbon monoxide poisoning and/or gas explosion.
