✦ Synopsis

Results are presented for the variation in burning velocities with equivalence ratio and reactant gases preheat temperature for a number of chlorinated hydrocarbon compounds in methane-air mixtures of different concentrations at atmospheric pressure. Flame velocity of the mixture is determined with a Bunsen burner by measuring the unignited mixture approach flow rates and the area of the flame front. The method provides acceptable results and compares favorably with widely published methane flame data. Activation energy for a particular chlorinated compound was calculated by relating the flame velocity to the overall combustion reaction rate. Results are compared with nonchlorinated compounds and the available data in the literature. The reasons for discrepancies are discussed. The results show that increasing chlorine content decreases flame velocity and shifts the maximum flame velocity from fuel rich toward fuel lean. The flame velocity increases with increasing gas preheat temperature.
