ABSTRACT:
Gross calorific content available from natural gas combustion determined from proportionality to molar oxygen demand in an apparatus including: provision for supplying gas and air at fixed, standard volumetric rates such that oxygen is present in excess; a combustion chamber employing swirled mixture introduction to effect complete gas burning; an oxygen sensor to detect deviation of combustion product oxygen content from an optimum setpoint value; an electrolytic hydrogen (oxygen) generator, the output of which adds to the gas and air mixture prior to combustion; and electronic control circuitry to maintain setpoint through regulation of an electrolysis current. Said current, or its control signal, also serves as a direct electronic meter of the generated species. Thus, through calibration, a measure of oxygen demand and calorific value is provided.
