    摘要： A directional device for an orifice member having a minimum orifice diameter and an orifice outlet end is disclosed. The orifice member conducts the fluid in an outward direction through the orifice outlet end. The directional device directs the fluid in a predetermined direction toward a work area and has a longitudinal member provided with an outlet end and an inlet end. The inlet end of the longitudinal member has an inlet end diameter equal to or less than the minimum orifice diameter. Packing means are disposed between the inlet end and the orifice outlet end. The packing means has a bonding strength sufficient to secure the inlet end of the longitudinal member to the orifice member during the transmission of the fluid through the directional device but insufficient to prevent the removal of the directional device from the orifice member into the work area without damage to or movement of the orifice member. A directional member is connected to the outlet end of the longitudinal member for directing the fluid in the predetermined direction into the work area.

    摘要： A method has been provided for the operation of a blast furnace wherein air is introduced in the blast furnace through a tuyere zone and an air flow maintained at high velocity. This method comprises of introducing the supplemental fuel into said tuyere zone and admixing the same with the air flowing through the tuyere zone; maintaining at least one lower velocity turbulent zone in said tuyere zone, said lower velocity being in respect to the velocity of the flowing air and supplemental fuel admixture, said lower velocity turbulent zone initiating and sustaining the combustion of said fuel; and controlling the amount of supplemental fuel consumed in the tuyere by varying the distance of the turbulent zone in respect to the zone at which the air flow exists from said tuyere. Apparatus illustrating various flow retarding devices and thus flame source and fuel combustion control means also have been disclosed.
