Fundamental studies have shown that tubular flame has potential for realizing many kinds of practical combustors, because the flammable range is very wide, the burner can burn various kinds of fuels with low NOx and SPM emissions, the burner is simple in structure and can be compact, and the tubular flame shape yields convenient ways to use. Based on these good points, recently developed tubular flame burners have been classified into four groups and briefly introduced in this paper; (1) wide flammable range, resulting in a torch burner which can burn blast furnace gas of low caloric heat, (2) fuel diversity, resulting in burners for by-product fuel gases, city gas, LPG, kerosene, banker A, banker C, and biomass powder, (3) simple and compactness, resulting in burners installed in the fuel processing system of PEFC, micro steam generator, and water heater, a burner for heating a hollow bolt, and a portable micro burner, and (4) tubular shape, resulting in a yellow flame generator for fireplace, a pilot flame for stabilizing main combustion in a high speed flow, an annular burner flame to assist PET powder combustion, and a Saturn-ring burner for heating a Stirling engine.
