 EMI1.1 
 



   Gegenstand der Erfindung ist ein Betriebsverfahren für Winderhitzer-(Cowper-)apparate, bei denen   de ? Kaltwind   durch eine Gebläsemaschine angesaugt und in die Winderhitzer   hineingedrückt   wird. Man hat bereits vorgeschlagen, eine Vorerwärmung dieses Gebläse windes dadurch herbeizuführen, dass man die Gebläsemaschine durch einen Kanal ansaugen lässt, welcher von dem die in den Winderhitzern verbrannten, abziehenden Hochofengase führenden Fuchs nur durch eine schwache Wand getrennt ist. Diese Anordnung bedeutet aber für die Gebläsemaschine eine starke Beanspruchung, da die Ansaugearbeit eine sehr ungünstige ist. Überdies ist es für die Beschaffenheit der Gebläsemaschine nachteilig, wenn sie warme Luft anzusaugen hat.

   Der Wert der Vorerwärmung wird ausserdem dadurch hinfällig, dass auf dem Wege von der   Gobläsemaschine   zu den Winderhitzerapparaten, der infolge der üblichen Bauart der Winderhitzeranlagen ein ziemlich   beträchtlicher     ist, Ten-   peraturverluste auftreten.

   Die Vorerwärmung der Luft findet in Wärmeaustauschapparaten statt, welche In die Abgaskanäle der Winderhitzerapparate eingebaut sind und mit ihren Zu-und Abgängen an die von der Gebläsemaschine zu den Winderhitzern führende Kaltwindleitnng angeschlossen sind. Der von der Gebläsemaschine kommende Wind passiert also bei seinem Durchströmen der Kaltwindleitung vor Eintritt in die Winderhitzerapparate den Wärmeaustauschapparat, wodurch der Kaltwind erheblich vorerwärmt wird.

 EMI1.1
 



   The subject of the invention is an operating method for Winderhitzer- (Cowper-) devices in which de? Cold wind is sucked in by a blower machine and pushed into the heater. It has already been proposed to preheat this blower wind by letting the blower machine suck in through a duct which is only separated from the fox leading the blast furnace gases burned in the blast furnace by a weak wall. However, this arrangement means a heavy load on the blower machine, since the suction work is very unfavorable. In addition, it is disadvantageous for the nature of the blower machine if it has to suck in warm air.

   In addition, the value of preheating becomes obsolete because temperature losses occur on the way from the Gobläsmaschine to the boiler, which is quite considerable due to the usual design of the boiler.
 EMI1.2
   machine sucked in air not in front of the blower machine, but behind it. Knurl before the wind enters the Winderbitzer apparatus itself. This results in more favorable stress on the machine and avoids temperature losses in the preheated air.

   The preheating of the air takes place in heat exchange devices which are built into the exhaust gas ducts of the boiler and are connected with their inlets and outlets to the cold air duct leading from the blower machine to the boiler. The wind coming from the blower machine passes through the heat exchange apparatus as it flows through the cold wind pipe before entering the wind heater apparatus, whereby the cold wind is considerably preheated.
