Combustion of Ethane with Small Concentrations of Methyl Chloride Tube Burner

Abstract

Abstract Premixed, thermally stabilized combustion inside a refractory-tube without a flameholder has a number of unique characteristics that are favorable for incineration. Owing to the fully developed turbulent flow, the velocity, temperature and composition are relatively uniform across the channel, Because of the absence of backmixing other than the negligible degree associated with confined turbulent flow, the flame front is a virtual step in temperature and composition. Owing to the thermal feedback by wall-to-wall radiation and in-wall conduction, the temperature of the stream of gas immediately behind the flame front exceeds the adiabatic value, and owing to the great thermal inertia of the refractory tube and the plug-like flow, the combustion is very stable and free of oscillations. Most important of all, the temperature of the wall is close to that of the gas throughout the burner. The net effect of these characteristics is that every molecule of the gaseous mixture experiences essentially the ...
