Fuel-lean premixed combustion is one of the effective methods to reduce NO_x emission from combustors. However, high-power lean combustion is difficult to realize in premixed flames, because their stability is worse compared with non-premixed flames. In the present study, a swirl flow combustor, which consists of an upright cylindrical chamber and two fuel nozzles installed tangentially on the side wall. near the bottom, was selected as a means to obtain such a stable premixed combustion. Experiments were conducted using propane as fuel. Then, it was found that this combustor has excellent performance for the stable combustion of the fuel-lean mixture, and that the stability is due to a toroidal flame with a forced recirculation flow, formed at the bottom along the inner wall of the combustor.
