Description
Tiegelöfen mit Gasheizung sind bekannt. Aber um hohe Temperaturen zu erreichen, mußte man bisher sogenannte reiche Gase (Leuchtgas) anwenden. Armes Gas wurde bisher nur selten, und zwar wohl allein zum Schmelzen leicht schmelzbarer Stoffe benutzt. Um armes Gas auch zum Schmelzen schwer schmelzbarer Stoffe (Kupfer, Nickel, Silber, Gold, Legierungen) gebrauchen zu können, hat man Gas und Luft vor dem Eintritt in den Heizraum erwärmt. Hierbei entsteht eine Schwierigkeit im Finden eines Erhitzers, der den besten Wirkungsgrad bei , kleinstem Raumbedarf gibt.Crucible furnaces with gas heating are known. But to get high temperatures so-called rich gases (luminous gas) had to be used up to now. Poor gas has only seldom been used so far, and probably only for the Melting easily fusible substances is used. To make poor gas difficult to melt too to be able to use fusible substances (copper, nickel, silver, gold, alloys), you have heated gas and air before entering the boiler room. This creates a Difficulty in finding a heater that has the best efficiency at the smallest Space requirement.
Nach der Erfindung wird diese Aufgabe folgendermaßen gelöst.According to the invention, this object is achieved as follows.
Man umgibt den feuerfesten Heizraum, in dem der Tiegel steht, mit einem metallischen Hohlzylinder, in welchen man das zu erwärmende Gas einführt. Stege im Innern1 dieses Hohlzylinders zwingen das Gas in einen Zickzackweg, wobei es die Wände'des Erhitzers bestreicht, der von innen her in seiner ganzen Höhe durch die Strahlung des Gemäuers und von außen her durch die den Ofen verlassenden heißen Verbrennungsgase bespült wird. Wenn das Gas genügend erwärmt ist, strömt es durch einen Kanal im Gemäuer in den Heizraum. Ein zweiter Erhitzer ähnlicher Bauart umgibt den ersten unter Belassung eines Zwischenraumes, durch den die heißen Abgase nach unten ziehen. Dieser zweite Erhitzer dient zum Erhitzen der Luft. Wenn sie die beabsichtigte Temperatur erreicht hat, wird sie durch ein Rohr, das den erstgenannten Erhitzer durchquert, in den Heizraum geleitet. The refractory boiler room in which the crucible is located is surrounded by a metallic hollow cylinder into which the gas to be heated is introduced. Bars in the interior 1 of this hollow cylinder force the gas into a zigzag path, brushing the walls of the heater, which is flushed from the inside in its entire height by the radiation of the masonry and from the outside by the hot combustion gases leaving the furnace. When the gas is sufficiently heated, it flows through a channel in the masonry into the boiler room. A second heater of a similar design surrounds the first one, leaving a space through which the hot exhaust gases pull down. This second heater is used to heat the air. When it has reached the intended temperature, it is passed into the boiler room through a pipe that passes through the first-mentioned heater.
In der. Zeichnung ist ein Ausführungsbeispiel eines Ofens dargestellt.In the. The drawing shows an embodiment of a furnace.
Der Tiegel A steht in eineni feuerfesten Heizraum B. Ihn umgibt der Erhitzer D, in welchen das Gas bei E eintritt. F ist der Austritt. Fig. β zeigt den Weg des im Erhitzer D erhitzten Gases. Die zu erhitzende Luft tritt bei / in den Erhitzer H ein und bei / wieder aus; sie durchläuft ihn in einem der Richtung des Gases entgegengesetzten Sinne. Wenn das Gas im Heizraum B verbrannt ist, wird es zwischen beiden Erhitzern D1 H hindurch durch einen Abzug im Boden abgeführt.The crucible A is in a fireproof boiler room B. It is surrounded by the heater D, into which the gas enters at E. F is the exit. Fig. Β shows the path of the gas heated in the heater D. The air to be heated enters the heater H and exits again at /; it passes through it in a sense opposite to that of the gas. When the gas in the boiler room B is burnt, it is discharged between the two heaters D 1 H through a flue in the floor.
