Abstract:	This paper presents a hydrogen-fueled micro-combustion system for thermophotovoltaic application. The thermal performances of the micro-combustor with and without baffles have been investigated numerically and experimentally. Dimensionless height λ and distance δ are defined to determine the optimal height and location of the baffles. The highest combustion efficiency is achieved when δ and λ are 0.3 and 0.9, respectively. The blowout limit is extended for the combustors with baffles. Besides, the heat from exhaust gas is recycled to preheat the fresh H2-air mixture, thereby increasing the mean wall temperature. A high H2-air mass flow rate will increase the fresh gas temperature but lead to low heat recovery rate. © 2013 Elsevier Ltd. All rights reserved.
