Description

Verfahren zur Vorbereitung (z. B. Trocknen) der Brenn- und Schmelzstoffe für ihre unmittelbare Einführung in die Schmelzzone von Schachtöfen. Es hat sich bekanntlich als zweckmäßig erwiesen, Schmelz- und Brennstoffe, die man unmittelbar in die Schmelzzone von Schachtöfen (Hochöfen, Gaserzeuger) einführen will, vo@zübereiten, beispielsweise zu erwärmen, zu trocknen oder zu reduzieren. Nach Patent 38z007 ist es nicht nötig, hierzu besondere Wärmequellen zu schaffen, wenn man die Eigenwärme der Ofengicht oder der Gichtgase ausnutzt. Dieses Verfahren ist aber nur dann anwendbar, wenn die Gichttemperatur ziemlich hoch liegt, was jedoch im Interesse eines guten Wirkungsgrades der Öfen zu vermeiden ist.Process for preparing (e.g. drying) the fuels and melting materials for their direct introduction into the melting zone of shaft furnaces. It has known to be useful, melting and fuels that can be used immediately want to introduce into the melting zone of shaft furnaces (blast furnaces, gas generators), prepare for example to heat, dry or reduce. According to patent 38z007 is it is not necessary to create special heat sources for this, if you can use the own heat exploits the furnace furnace or furnace gases. However, this procedure can only be used when the top temperature is quite high, which is in the interests of a good one Efficiency of the ovens is to be avoided.

Gemäß vorliegender Erfindung benutzt man zur Vorbereitung solcher Schmelz- und Brennstoffe, die im Hüttenbetrieb bereits vorhandene Wärme- und Abhitzequellen.According to the present invention, such is used for the preparation Melts and fuels, the heat and waste heat sources already present in the smelter.

Man führt beispielsweise in Winderhitzern und anderen Wärmespeichern vorgewärmte Luft oder erhitzten Gebläsewind der Trocken- oder Wärmevorrichtung zu.One leads, for example, in hot water heaters and other heat storage systems preheated air or heated fan wind to the drying or warming device.

Ebenso kann man die aus den Winderhitzern beim Umstellen derselben von Wind auf Gas ausströmende heiße Luft, die bisher nutzlos ins Freie gelassen wurde, auffangen und in besonderen Leitungen der Wärmevorrichtung zuführen.Likewise, you can remove the ones from the hot air heaters when you move them hot air escaping from wind to gas, which was previously uselessly let into the open air was collected and fed in special lines to the heating device.

Als weitere Wärmequelle kommt die Abgabe der Winderhitzer, Dampfkessel, Gasmaschinen und metallurgischen Öfen (Kupolöfen und Martinöfen) u. dgl. in Betracht. Diese haben zugleich den Vorzug, daß infolge ihres Mangels an Sauerstoff eine oxydierende Wirkung auf die Stoffe vermieden wird. Die heißen Abgase werden den Kanälen durch Ventilatoren und ähnliche Fördervorrichtungen entnommen, falls die Wärme- und Trockenvorrichtungen nicht unmittelbar zwischen Öfen oder Feuerungen und Kamine eingeschaltet sind. Bei Öfen mit Druckgas- und Druckluftbeheizung, beispielsweise bei Kupolöfen und mit Druckluft betriebenen Winderhitzern, sind Exhaustoren und Kamine entbehrlich.Another source of heat is the output of the boiler, steam boiler, Gas machines and metallurgical furnaces (cupolas and martin furnaces) and the like can be considered. These also have the advantage that, due to their lack of oxygen, they are oxidizing Effect on the substances is avoided. The hot exhaust gases are going through the ducts Fans and similar conveying devices removed, if the heating and drying devices are not switched on directly between stoves or fireplaces and chimneys. at Furnaces with compressed gas and compressed air heating, for example with cupolas and with Compressed air operated hot air heaters, exhaustors and chimneys are dispensable.

Die in vorliegenden Ausführungsbeispielen beschriebenen Verfahren können sowohl einzeln für sich wie auch gleichzeitig zur Anwendung kommen.The methods described in the present exemplary embodiments can be used individually or at the same time.

Die Erwärmung und Trocknung der Stoffe erfolgt entweder unmittelbar, indem man die Wärme führenden Gase in Trockentrommeln u. dgl. unmittelbar über das zu trocknende Gut hinwegstreifen läßt oder dieselbe in feinem Strom den Abgasen in senkrechten Fallröhren entgegenführt, oder aber mittelbar in Vorrichtungen, die durch diese Wärmequellen von außen beheizt werden.The fabrics are either heated and dried immediately, by placing the heat-carrying gases in drying drums and the like directly over the The goods to be dried can be wiped away or the same in a fine stream of the exhaust gases in vertical downspouts, or indirectly in devices that be heated from the outside by these heat sources.
