Title

Development Of A Porous Combustor For The Efficient Extraction Of Thermal Energy From Liquid And Gaseous Fuels

Abstract

In this study, a porous burner has been developed to efficiently convert gaseous and liquid fuels to thermal energy utilizing coupled heat feedback and combustion. A solid phase introduced to the combustion reaction is the first feedback device. A second feedback system, a post combustion heat exchanger with user controllable relief valves preheats the systems incoming gaseous flow. Elevated temperatures of the gaseous flow thus enable evaporation of liquid fuels as they continue into the flow stream. As a supplemental design tool, a network combustion model was developed and implemented in CHEMKIN-PRO software. Qualitative validation of the model was ensured maintaining the equivalence ratio at φ = 0.50 by varying the reactant flow rate-demonstrating the ability of the burner to respond to throttling of the firing rate. Comparisons between the effects of firing rate changes on the downstream temperature of the flow are drawn in addition to the position of the reaction within the combustion chamber. Demonstration of the burner's ability to run on liquid kerosene fuel is also presented as well as the lowest achievable equivalence ratio.
