Description
Elektrisch beheizter Speicher ofen Die Erfindung bezieht sich auf einen elektrisch beheizten Speicherofen mit einer Wärmequelle, einen Lade- bzw. Entladegebläse und einem Feststoffwärmespeicher.Electrically heated storage furnace The invention relates to an electrically heated storage heater with a heat source, a charging or Discharge fan and a solid heat storage.
Bei den bekannten Geräten dieser Art ist der Speicherkern aus Pormsteinen zusammengesetzt, die aus Xagnesit oder einem ähnlichen geeigneten Material bestehen. Die Heizelemente sind ueber den Speicherkern verteilt angeordnet, wobei die von den Heizelementen erzeugte Wärme teils durch Leitung, teils durch Strahlung auf das Speichermaterial übertragen wird.In the known devices of this type, the storage core is made of Porm stones composed of xagnesite or a similar suitable material. The heating elements are distributed over the storage core, with those of the heating elements generated heat partly by conduction and partly by radiation the storage material is transferred.
Wegen der begrenzten Temperaturfestigkeit der Heizelemente muß die Speichertemperatur verhältnismäß niedrig gehalten und deshalb die Speichermasse entsprechend groß gewählt werden, wodurch sich das Gewicht und der Raumbedarf des Speichers wesentlich erhöht. Außerdem ist das Auswechseln von beschädigten Heizelementen verhältnismäßig aufwendig.Because of the limited temperature resistance of the heating elements Storage temperature kept relatively low and therefore the storage mass be chosen accordingly large, which increases the weight and space requirements of the Storage increased significantly. In addition, the replacement of damaged heating elements relatively expensive.
rufgabe der Erfindung is es, eine Möglichkeit zur Erhöhung der Speicherspitzentemperatur zu schaffen und die Auswechselbarkeit von Heizelementen zu vereinfachen.The object of the invention is to provide a way of increasing the storage peak temperature to create and to simplify the interchangeability of heating elements.
Erfindungsgemäß werden diese Aufgaben dadurch gelöst, daß der Wärmespeicher aus einer luftdurchlässigen Schüttung feinkörniger Peststoffteilchen, z.B. Keramikteilchen, besteht und die Wärmequelle in dem vom Gebläse geförderten Ladeluftatrom vor dem Wärmespeicher angeordnet ist. Bei einem derartig ausgebildeten Speicherofen ist der Heizwiderstand leicht zugänglich und gegen tberhitzung geschützt, da er ständig von Frischluft umströmt ist.According to the invention, these objects are achieved in that the heat accumulator from an air-permeable bed of fine-grained pest particles, e.g. ceramic particles, exists and the heat source in the charge air conveyed by the fan before the Heat storage is arranged. In the case of a storage heater designed in this way the heating resistor is easily accessible and protected against overheating because it is constantly is surrounded by fresh air.
Eine besonders gleichiäßige Wärmeabgabe eines erfindungsgemäß ausgebildeten Speichers ergibt sich, wenn der Wärmespeicher nach einer weiteren Ausbildung der Erfindung in einzelne in Abhängigkeit vom Lade- bzw. Entladezustand an das Gebläse anschließbare Zonen unterteilt ist, die nacheinander entladen werden können.A particularly uniform heat emission from one designed according to the invention Storage results when the heat storage after another Formation of the invention in detail depending on the state of charge or discharge zones which can be connected to the fan and which are discharged one after the other is divided can.
Dsbei ist ee besonders vorteilhaft, wenn die Umsteuerung des Entladeluftstromes von einer Speicherzone auf eine andere selbsttätig in Abhängigkeit von dem temperaturabhängigen Durchströmwiderstand des Speichermaterial erfolgt.This is particularly advantageous if the reversal of the discharge air flow from one storage zone to another automatically depending on the temperature-dependent Flow resistance of the storage material takes place.
Diese Maßnahmen haben auch eine bessere Nutzung der Speicherkapazität zur Polge.These measures also have better use of storage capacity to the Polge.
In der Zeichnung ist ein Ausführungsbeispiel eines erfindungsgenLäß ausgebildeten Speicherofens schematisch dargestellt.In the drawing is an embodiment of a erfindungsgenLäß trained storage furnace shown schematically.
In einem Gehäuse 1 ist eine luftdurchlässige Schüttung 2 aus feinkörnigen Feststoffteilchen angeordnet. Im Ströiungsweg eines in den Innenraum des Behälters 1 führenden Luftkanal,s 3, der im Ladebetrieb an ein Gebläse 4 angeschlossen ist, befindet sich ein elektrisches Heizelenent 5. Ix Entladebetrieb ist der Luftkanal 3 an eine zu den Verbrauchern führende Leitung 6 angeschlossen. In dieser Betriebsphase fördert das Gebläse 4 Uber eine Leitung 7 Frischluft durch die Speichermasse 2. Die Leitung 7 weist mehrere Verzweigungen 8 auf, die~in verschiedenen Höhen in das Gehäuse 1 eingeführt und denen Absperrmittel 9 zugeordnet sind, so daß die vom Gebläse 4 geförderte Prischluft wahlweise auf serschiedenen Höhen in die Speicheriasse 2 eingeblasen werden kann.In a housing 1 is an air-permeable bed 2 made of fine-grained Solid particles arranged. In the Ströiungsweg one in the interior of the container 1 leading air duct, s 3, which is connected to a blower 4 in charging mode, there is an electrical heating element 5. Ix discharge mode is the air duct 3 connected to a line 6 leading to the consumers. In this operating phase The fan 4 conveys fresh air through the storage mass 2 via a line 7. The line 7 has several branches 8, the ~ at different heights in the Housing 1 introduced and which shut-off means 9 are assigned, so that the blower 4 conveyed prischluft optionally at different heights in the storage class 2 can be blown in.
