✦ Synopsis

Heat balances were studied in a iet of heated nitroaen issuiw into cool ethane-air. Rates of heat production were obtazned io7 the oxidation of ethane-at low concentration near thk axis of the jet. Assuming the course of reaction to be unchanged at all temperatures (800D to 873%) and fuel concentrations used, the order of reaction-is unity with'respect to fuel and 0.25 with respect to oxygen. The activation energy is about 49 kcallmole. These values were tested by prediction of the hot-gas ignition temperature, assuming a purely thermal ignition, and by use in the Spalding centroid procedure to predict burning velocity.
