Abstract
A gas combustion apparatus is disclosed wherein an oxygen sensor having electrodes on both surfaces of a base body is fixed in advance at a position such that the oxygen sensor is within the exhaust gas a combustion flame under normal conditions and a combustion flame under oxygen deficiency conditions is brought into contact with only the measuring side electrode. The oxygen sensor is preferably mounted to a heat-resistance holder having an opening such that the measuring side electrode corresponds with the opening.
