In view of diminishing resources of fossil fuel, it is very important to device future combustion systems, which are capable not only for utilizing low quality fuels but also realizing ultra-low pollutant emission. According to the concept by Weinberg, a variety of heat recirculation type lean-burn burners have been proposed. Since they have complicated construction and exhibit extreme large pressure loss, however, wide application to industrial and commercial combustion systems have not been positively realized. In this paper an insert-type compact regenerative burner, which is not necessary for any additional equipments, is devised and its lean-burn characteristics are experimentally investigated. It is found that ultra-lean propane-air mixture of an equivalence ratio of φ = 0.19, being extremely leaner than the lean flammability limit of φ = 0.51 under STP, is successfully burned.
