ABSTRACT:
A method and device 15 is provided for a quick, accurate and on-line determination of heats of combustion of gaseous hydrocarbons. First, the amount of oxygen in the carrier stream air is sensed by oxygen sensing system 20. Second, three individual volumetric flow rates of oxygen, carrier stream air, and hydrocarbon test gas are introduced into burner 19. The hydrocarbon test gas is fed into burner 19 at a volumetric flow rate n measured by flowmeter 18. Third, the amount of oxygen in the resulting combustion products is sensed by oxygen sensing system 20. Fourth, the volumetric flow rate of oxygen is adjusted until the amount of oxygen in the combustion product equals the amount of oxygen previously sensed in the carrier stream air. This equalizing volumetric flow rate is m and is measured by flowmeter 16. The heat of combustion of the hydrocarbon test gas is then determined from the ratio m
