Flow and combustion characteristics of coaxial crossed swirling fluidic process were studied by experimentation in the article. The study shows that the finestra current coefficient of fluidic equipment of central tube spout was 0.605; the resistance coefficient of circumrotation vane was 0.09; the ejective gas from the spout formed a negative pressure area at the center of spout; the axial velocity decayed faster; the excess air coefficient required for combustion was small; the combustion which flame was transparent and vigorous was full. The effective and clean combustion of low calorific gas-fired can be realized with the coaxial crossed swirling fluidic combustor in the tube furnace of coal chemical plant.
