Title (EN) BLAST FURNACE HAVING ENERGY-SELF-SUFFICIENT MONITORING OF CARBON INJECTION
(FR) HAUT FOURNEAU MUNI D'UN DISPOSITIF AUTOSUFFISANT D'OBSERVATION DE L'INJECTION DE CARBONE
(DE) HOCHOFEN MIT ENERGIEAUTARKER BEOBACHTUNG VON KOHLENSTOFFEINBLASUNG
Abstract:
(EN) The invention relates to a blast furnace (1) having a shaft-shaped furnace wall (2), which surrounds a process chamber (3), in which iron ore (4) is smelted in order to form iron (5). The furnace wall (2) has openings (8) on the periphery of the furnace wall, via which openings a hot-air blast (9) is supplied to the process chamber (3). The furnace wall (2) is surrounded by a ring line (10), in which the hot-air blast (9) is guided. Tapping lines (11) proceed from the ring line (10) and end at the openings (8) of the furnace wall (2). The tapping lines (11) consist of steel pipe (12), which is lined with a fireproof material (13) on the inside. Injection lances (16) end in the region of the openings (8), by means of which injection lances coal dust (17) is added to the hot-air blast (9), which coal dust burns inside the process chamber (3). Sensor devices (18) associated with the tapping lines (11) have sensing devices (19), by means of which the burning of the coal dust (17) is monitored. The sensor devices also have transmission devices (20), which are connected to the sensing devices (19) in respect of data transfer and by means of which data concerning the monitored burning can be wirelessly transmitted. The sensor devices (18) also have thermoelectric converters (21), which are thermally coupled to the tapping lines (11) and which produce electrical energy from the temperature difference between the tapping lines (11) and the environment of the blast furnace (1), by means of which electrical energy the sensor devices (18) are supplied with electrical energy. The steel pipes (12) of the tapping lines (11) have cut-outs (26) in partial regions. The thermoelectric converters (21) are arranged there.
(FR) L'invention concerne un haut fourneau (1) qui comprend une paroi de four en forme de cheminée (2) qui encercle une chambre de procédé (3) dans laquelle le minerai de fer (4) est fondu pour donner du fer (5). La paroi du four (2) présente, sur son pourtour, des ouvertures (8) par l'intermédiaire desquelles de l'air chaud (9) est amené à la chambre de procédé (3). La paroi de four (2) est entourée d'une conduite circulaire (10) dans laquelle est conduit l'air chaud (9). Des conduites de dérivation (11) qui se terminent au niveau des ouvertures (8) de la paroi du four (2) partent de la conduite circulaire (10). Les conduites de dérivation (11) se composent d'un tube en acier (12) qui est habillé à l'intérieur d'un matériau réfractaire (13). Des lances d'injection (16) permettant d'additionner l'air chaud (9) de poussière de charbon (17) qui brûlera à l'intérieur de la chambre de procédé (3) aboutissent dans la zone des ouvertures (8). Des systèmes de détection (19) permettant d'observer la combustion de la poussière de charbon (17) présentent des systèmes de capteur (19) affectés aux conduites de dérivation (11). Ils présentent également des systèmes de transmission (20) permettant d'envoyer sans fil des données sur les combustions observées et qui sont reliés par informatique aux systèmes de détection (19). Les systèmes de capteur (18) présentent en outre des convecteurs thermoélectriques (21) qui sont couplés thermiquement aux conduites de dérivation (11) et qui produisent de l'énergie électrique à partir de la différence de température entre les conduites de dérivation (11) et l'environnement du four (1), permettant d'alimenter en énergie électrique les systèmes de capteurs (18). Les tubes en acier (12) des conduites de dérivation (11) présentent dans des zones partielles des cavités (26). C'est là que sont disposés les convertisseurs thermoélectriques (21).
(DE) Ein Hochofen (1) weist eine schachtförmige Ofenwand (2) auf, die einen Prozessraum (3) umschließt, in dem Eisenerz (4) zu Eisen (5) verhüttet wird. Die Ofenwand (2) weist an ihrem Umfang Öffnungen (8) auf, über welche dem Prozessraum (3) Heißwind (9) zugeführt wird. Die Ofenwand (2) ist von einer Ringleitung (10) umgeben, in welcher der Heißwind (9) geführt wird. Von der Ringleitung (10) gehen Stichleitungen (11) ab, die an den Öffnungen (8) der Ofenwand (2) enden. Die Stichleitungen (11) bestehen aus Stahlrohr (12), das innen mit einem Feuerfestmaterial (13) ausgekleidet ist. Im Bereich der Öffnungen (8) enden Injektionslanzen (16), mittels derer dem Heißwind (9) Kohlestaub (17) zugesetzt wird, der innerhalb des Prozessraums (3) verbrennt. Den Stichleitungen (11) zugeordnete Sensoreinrichtungen (19) weisen Erfassungseinrichtungen (19) auf, mittels derer die Verbrennung des Kohlestaubs (17) beobachtet wird. Sie weisen weiterhin mit den Erfassungseinrichtungen (19) datentechnisch verbundene Übermittlungseinrichtungen (20) auf, mittels derer Daten über die beobachteten Verbrennungen drahtlos aussendbar sind. Die Sensoreinrichtungen (18) weisen ferner thermoelektrische Konverter (21) auf, die an die Stichleitungen (11) thermisch angekoppelt sind und die aus der Temperaturdifferenz zwischen den Stichleitungen (11) und der Umgebung des Hochofens (1) elektrische Energie erzeugen, mittels derer die Sensoreinrichtungen (18) mit elektrischer Energie versorgt werden. Die Stahlrohre (12) der Stichleitungen (11) weisen in Teilbereichen Ausnehmungen (26) auf. Dort sind die thermoelektrischen Konverter (21) angeordnet.
