Abstract: The sample of the gaseous fuel mixture to be analyzed is directed from the feed line leading to a combustion chamber and circulated through a flame arrestor and gas flow meter to a combustion mixture analyzer having an oxygen solid electrochemical cell contained therein. The fuel mixture is heated above its ignition temperature to obtain complete chemical equilibrium and the excess oxygen and/or fuel that remains, if any, mixed with the products of combustion circulate around the outer surface of the electrochemical cell. A suitable readout device measures the EMF produced across the electrodes of the cell when a gas of known partial pressure comes in contact with the inner surface of the electrochemical cell. The fraction of excess oxygen above that required for stoichiometric combustion that remains in the gaseous products of combustion is determined by the formula:
