Influence of Water Vapour upon the Combustion of Hydrocarbon Mixtures

Abstract

IT has been reported previously that flame gases resulting from the combustion of moist carbon monoxide – air and moist hydrogen – air mixtures attain higher temperatures than those resulting from the combustion of dry mixtures^1,2. The temperatures were measured by means of very thin quartz-covered platinum-rhodium wires of overall diameter 0.0005 in. immersed in the flame gases just above the inner cone. The mixtures which were fed to the burner were on the weak side of the theoretical mixtures, and for any given combustible gas content the temperatures of the moist mixture flame gases were of the order of 50° C. higher than those of the dry mixture flame gases.
