THE EFFECT OF PREHEATING A BENZENE-AIR MIXTURE ON THE FLAME PROPAGATION VELOCITY
Abstract
A study was made of the effect of preheating a benzene-air mixture on the flame propagation velocity under conditions of both laminar and turbulent flows. The temperature of the mixture delivered to the burners varied from 17 to 227 C. The temperature of the fuel mixture was maintained by a thermocouple at the burner outlet before the instant of ignition. The flame propagation velocity was determined by photographing the flame cone at the burner. Results showed a noticeable increase in the flame propagation velocities with an increase in temperature, somewhat different for different ranges of concentrations. The velocities increased considerably in the region where the fuel was insufficient, while the effect was weaker near the upper boundary of combustion. The effect of the initial preheating of the flame propagation velocity was the same under conditions of turbulent and laminar regimes.
