Abstract: Tangentially-fired furnaces are vortex-combustion units and are widely used in steam generators of thermal power plants. The stability of a flame inside the furnace depends on many parameters such as the inclination angle and the flow rates in the burners for each of the furnace corners. The inclination angle is the angle between the burner axis and the diagonal of the furnace. In the present paper, we provide measurements of stability limits and temperature-contour maps in a water-cooled, tangentially-fired model furnace. The limits of ignition are found to depend on the size of the vortex and the inclination angle. The stability limits are analyzed in view of measured temperature-contour maps.
