摘要:
A detection wave from a transmitting/receiving means is guided to the interior of a blast furnace via an antenna and a reflecting plate, and when a reflected wave from the surface of a loaded material is reflected by the reflecting plate and received by the transmitting/receiving means, the reflecting plate is rotated together with the antenna, or the reflecting plate is rotated additionally, and the surface profile of the loaded material is measured by scanning the surface of the loaded material in a linear manner or a planar manner during the turning of a chute or for each prescribed turn of the chute. A deposition profile is obtained on the basis of this surface profile and is compared to a predetermined theoretical deposition profile, and the chute is controlled so as to correct the error with respect to the theoretical deposition profile and then which new loaded material is introduced. The blast furnace is operated using this loading method.

The invention relates to a device for the thermal processing of divided solids, that comprises at least one transfer member (17) having a longitudinal axis (X) and a helical portion (18) mounted so as to rotate about said longitudinal axis in a tubular housing (11), wherein said helical portion (18) has a heating surface defining a heating transfer means. According to the invention, the tubular housing (11) has inner walls (41, 42) made of a refractory material, and the helical portion (18) of the transfer member (17) further defines a means for heating the inner walls (41, 42) to a temperature sufficient so that the inner walls themselves define a means for heating by radiation the mass of divided solids flowing in said tubular housing (11).

Disclosed is an ash-melting furnace which can respond to fluctuations in the load and is capable of highly efficient and stable operation. In an ash-melting furnace which heats and melts primary ash (ash containing rough particles) and fly ash (ash containing minute particles) obtained by combustion together, the primary ash is supplied from an upper end of the furnace to form an upper layer of a two-tiered layer of ash, and the fly ash is supplied from the upper end of the furnace to form a lower layer of a two-tiered layer of ash. The two-tiered layer together is moved towards the far end of the furnace, and is heated and melted by a burner (10) to form molten slugs (25a) during the moving step. When the burner is an oxygen-enriched burner, this configuration makes it possible to control the volume of oxygen to be added to the burner air (including changing the density of the oxygen). This invention can control not only the volume of fuel but also the density of the oxygen-enriched air and the volume of the ash to be supplied in response to the state of flow of the molten ash melted by the oxygen-enriched burner.

A rotary hearth furnace is provided to simplify detachment and assembly operations of a reduced iron discharging screw. At both side walls of an insulating housing 2a constituting in part of a furnace body 2 of a rotary hearth furnace 1 are installed through-holes which a spiral blade 42 of a reduced iron discharging screw 4 can pass through, each of the through-holes is closed by an inner hatch member 8 and an outer hatch member 9 which are externally mounted in a removable fashion to a rotary shaft 41 of the reduced iron discharging screw 4, an inner screw supporting device 10 is installed in the outside at an inner periphery side of the hearth 3 as well as an outer screw supporting device 20 is installed in the outside at an outer periphery side of the hearth 3. The reduced iron discharging screw 4 is detached from the furnace body 2 via the through-holes and assembled to the furnace body 2 via the through-holes by using the inner screw supporting device 10 and the outer screw supporting device 20.
摘要:
Anlage zum Trocknen und Aufbereiten von rieselfähigem mineralischem Gut mit einer Verbrennungseinrichtung (2), deren Rauchgase im Gleichstrom mit zu behandelndem Gut in eine drehend angetriebene Drehtrommel (1) eingeführt werden. Die Drehtrommel (1 ) ist in Förderrichtung geneigt, weist am Innenumfang Einbauten (3, 4, 5) auf und ist am deren Auslaßende dicht an einen Schacht (6) angeschlossen. Die Einbauten im vorderen Einführungsbereich sind Transportschaufeln (3). Der Schacht (6) ist mittels eines Ventilators (7) unter Unterdruck gesetzt und zur Übernahme des aus der Drehtrommel (1) austretenden Gutes und Gasstroms eingerichtet. In der Drehtrommel (1) ist vor dem Auslaß ein Venturieinbau (8) koaxial und im Einführungsbereich ein Bypass (9) für Förderluft im Trommelmantel angeordnet.
