ABSTRACT:
An apparatus and method for determining the heating value of gaseous fuels is disclosed which include the novel means for establishing a mixture of air and the gaseous fuel of interest in known volumetric proportions. An electrochemical sensor is provided to sense the products of combustion of the precise volumetric mixture and the output of the sensor is indicative of the relation of the mixture to a stoichiometric mixture of fuel and air. This system is provided for adjusting the proportions of fuel and air in the mixture of interest in response to the output of the electrochemical sensor until the sensor indicates that the mixture of known proportions is substantially stoichiometric. The system is provided for determining the heating value of the fuel from a known relationship between the heating value of the constituents of the fuel and the amount of oxygen required for stoichiometric combustion.
