A142 Combustion Characteristics of Mezo-Scale Burner Using Rapid Flame Propagation in a Vortex Flow and Heat Recirculation

Abstract

The characteristics of mezo-scale combustors having characteristics of high speed flame propagation in a vortex flow and method of heat recirculation combustion were examined. The limits of flame stabilization in the mezo-scale combustors did not approach the lower limits of flammability under the conditions of preheated temperatures of the unburned gas. The characteristics of the space heating rate (SHR) of the combustor were similar to those of combustors of various sizes using various kind of fuels.
