摘要： A directional fluid heat control system for a high temperature kiln with a process zone. The system includes two rigid, coaxially aligned tubes positioned in the kiln. One tube rotates inside the other. One tube has a series of longitudinal openings, while the other has a series of helically arranged openings. Rotating one tube selectively aligns an opening from that tube with an opening in the other. Further rotation aligns different such pairs of openings with different longitudinal orientations in the kiln. The aligned openings release pressurized fluid from the inner tube into desired locations in the kiln's process zone.

摘要： A method and a control device for operating a furnace, in particular an anode furnace, formed by a plurality of heating channels and furnace chambers, the furnace chambers serving to receive carbonaceous products, in particular anodes, and the heating channels serving to control the temperature of the furnace chambers. The furnace includes at least one furnace unit that contains a heating zone, a fire zone and a cooling zone, which for their part are formed by at least one section that has furnace chambers. A suction ramp of the furnace unit is disposed in a section of the heating zone, and a burner ramp of the furnace unit is disposed in a section of the fire zone. Process air in the heating channels of the fire zone is heated by the burner ramp, and exhaust gas is suctioned from the heating channels of the heating zone by the suction ramp, while operation of the ramps is controlled by a control device of the furnace unit. The control device is used to determine respective enthalpy flow rates for at least two sections, where a difference of the respective enthalpy flow rates being determined as a characteristic, to compare such characteristic to a presupposed characteristic, and to determine a status of the furnace based on this comparison.

摘要： A side surface unit of a heat treatment space S is formed by a shutter member 250 including an outer shutter 260 and an inner shutter 270. Supply air A is supplied as a horizontal laminar flow toward a wafer W from a lower end side of the shutter member 250, that is, from a gap d1 located on the level with the wafer W placed on a heat plate 211 of a mounting table 210. Supply air B is supplied into the heat treatment space S from an upper end side of the shutter member 250, that is, from a gap d2 positioned higher than the wafer W. A ratio between a flow rate of the supply air A and a flow rate of the supply air B is 4:1.
