A tubular flame can be established in a rotating, axisymmetric, stretched flow field. This flame consists of an inner region of hot burned gas and an outer region of cold unburned gas, between which exists a thin reaction zone of tubular shape. Due to its symmetrical temperature distribution, an almost adiabatic condition can be achieved. In addition, the flame is aerodynamically stable for rotational motion. Thus, the tubular flame has potentialities for practical combustor. This paper reports a recent progress of the tubular flame burner; establishment of a uniform, large-area flame and of very safe, rapid mixing type combustion free from flame flash-back. Various kinds of fuels such as methane, propane, kerosene, heavy-oil, and also blast furnace gas of low caloric value can be burned in tubular flame burners.
