This work investigates experimentally a novel heat-regenerating burner capable of operating at high temperatures and over wide fuel-air ratios, including ultralean mixtures. A high-efficiency burner consists of a heat exchanger (regenerator) and a combustion chamber. The heat regenerator is a rotarytype, and is made of ceramic ; the exit port of the regenerator is a burner port. Heat is stored in the ceramic channel walls, which pre-heats the inlet fuel-air mixture to a high temperature prior to combustion. Both temperature profiles and species concentration profiles in the combustion chamber have been measured, and the heat transfer and combustion performance has been characterized. For the case of constant heat generation, steady combustion is established over a wide range of fuel air mixture ratio from 0.2 to 6.
