Design Of A Flow Controlled Heterogeneous Combustor With Multiple Instrumentation Techniques For The In-Situ Evaluation Of Combustion Catalysts

Abstract

Heterogeneous combustion is an advanced combustion technique which incorporates a highly porous ceramic within a combustion chamber. Placing a porous solid within the combustion chamber enables heat recirculation which is not present in homogenous combustion and as a result such combustion technology can enable enhanced lean burning operation, reduced emissions of CO and NOx, and increase in the maximum stable flame speed compared to laminar flames [1]. A novel design for a robust heterogeneous combustor is presented which does not feature flow modifying devices to control the flame position and instead, relies on the control of fuel and air mixtures to position the flame; it is the intention to utilize this combustor to examine various novel catalysts to assist combustion. Demonstration of the combustor is done using a methane-air fuel mixture along with an uncoated silicon carbide (SiC) media of 10 pores per inch (ppin) within the combustion chamber, though it is also possible to utilize various liquid fuels with this combustor. This combustor also includes several instrumentation devices, axial thermocouples, exhaust gas sampling, and a novel instrumentation technique for heterogeneous combustors: an externally mounted thermocouple which enables for the collection and analysis of acoustic emissions from the combustor exhaust.
