ABSTRACT:
A method of and means for changing the direction of flow of the products of combustion leaving a fuel fired burner. Located adjacent to the discharge end of a combustion chamber of the burner is a quarl or burner block having a convex surface defining a deflection path which follows closely said surface and along which the projected combustion products are caused to flow under the influence of surrounding gaseous pressures. The passage through the quarl in advance of the convex surface is restricted, for example by an encroachment of the convex surface into the passage and a deflector lip projecting into the passage opposite to said encroachment. The quarl may be inserted in the wall of a furnace at right angles thereto and without projecting therebeyond to direct the combustion products along the wall surface.
