INVESTIGATION OF THE MECHANISMS OF DECOMPOSITION, COMBUSTION, AND DETONATION OF SOLIDS

Abstract

Apparent flame strengths for the NH3-O and NH3 O-Cl reactions have been determined as a function of reactor pressure, using the opposed-jet echnique and 0.77-cm-ID nozzles. It has ben shown that the NH3-O flame strength is dependent on the square of the reactor pressure when both 0.46- and 0.77-cm jets are used. The proportion ality of the flame strength with the diameter of the jet, which is required by theory, has also been demonstrated. Apparent flame strength measurements for NH3 as fuel, with O-Cl mixture as oxidizer, have been made at 300, 450, 600 and 745 torr. The flame strength was inversely proportional to the mass fraction of Cl2 in the mixture. Extrapolations to zero flame strength indicated that no flame is possible at mass fractions of Cl of approximately 0.5. Analyses of the data for NH3-O-Cl systems indicate that Cl does not act as a diluent but competes with O in reaction with NH3. The three- component system also shows flame strength dependence on the square of the reactor pressure.
