Description

Die Erfindung bezieht sich auf eine Verdampferkammer gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to an evaporator chamber according to the Preamble of claim 1.

Eine entsprechende Verdampferkammer ist dem Prinzip nach aus einem Brenner nach der WO 0012935 A bekannt. Bei derartigen Brennern wird die nach Leistung des Brenners dosierte Ölmenge in der Verdampferkammer verteilt, durch Wärmezufuhr zur Verdampfung gebracht und mit der von einem Gebläse zugeführten Verbrennungsluft noch innerhalb des auch unter der Bezeichnung "Flammenhalter" bekannten Brennerrohres gemischt. An den Wandungsöffnungen des Brennerrohres tritt das Öldampf-Luftgemisch aus, wird gezündet und zur Verbrennung gebracht. Die für die Verdampfung des Heizöles benötigte Wärmeenergie wird in der Startphase durch die elektrische Widerstandsheizung erzeugt und während des Normalbetriebes durch Aufheizung der Verdampferkammer über die umgeleiteten heißen Verbrennungsgase bzw. Flammen zugeführt. Die bekannte Verdampferkammer hat einen relativ geringen Wärmewirkungsgrad der Elektroheizung für die Verdampfung und benötigt daher eine höhere elektrische Anschlußleistung. Überdies muß auch ein relativ größerer Anteil der heißen Verbrennungsgase zu der Außenseite der Verdampferkammer umgeleitet werden, um im Dauerbetrieb die ausreichende Verdampfung und Vorerhitzung des Heizöles zu gewährleisten.A corresponding evaporator chamber is made up of one principle Burner known from WO 0012935 A. With such burners amount of oil distributed according to the burner's output distributed in the evaporator chamber, brought to evaporation by the supply of heat and with that of one Combustion air supplied to the blower is still within the also under the Designation "flame holder" known burner tube mixed. To the The oil vapor-air mixture emerges from the wall openings of the burner tube ignited and brought to combustion. The one for the evaporation of the heating oil The required thermal energy is generated in the start-up phase by the electrical resistance heating generated and during normal operation by heating the Evaporator chamber via the redirected hot combustion gases or Flames fed. The known evaporator chamber is relatively small Thermal efficiency of the electric heater for evaporation and needed therefore a higher electrical connected load. In addition, a relative must greater proportion of the hot combustion gases to the outside of the evaporator chamber be redirected to the sufficient in continuous operation To ensure evaporation and preheating of the heating oil.

Aus der DE 42 38 718 A ist die zweiteilige Ausführung der Verdampferkammer bekannt. Die auch hier vorgesehene elektrische Widerstandsheizung ist in Form von Rohrheizkörpern in an der Unterseite des Unterteiles vorgesehene Nuten eingesetzt. Dieser Unterteil ist vom angesetzten Mantel durch eine isolierende Zwischenlage getrennt, so daß die Heizung im wesentlichen nur zur Erhitzung des Unterteiles dient. DE 42 38 718 A is the two-part design of the evaporator chamber known. The electrical resistance heating also provided here is provided in the form of tubular radiators in the bottom of the lower part Grooves used. This lower part is from the attached coat by one insulating liner separated so that the heater is essentially only for Heating the lower part is used.

Nach der JP 59009418 A ist bei einer ebenfalls zweiteiligen Verdampferkammer die Heizung in nach unten offenen Nuten eines gegenüber dem schalenförmigen Unterteil verdickten Mantelteiles angebracht.According to JP 59009418 A is also a two-part evaporator chamber the heating in downwardly open grooves one opposite the bowl-shaped Lower part of the thickened jacket part attached.

Zur Verbesserung des Wärmeüberganges der heißen Verbrennungsgase auf den Mantel der Verdampferkammer ist es schließlich aus der EP 0 220 384 A bekannt, diesen Mantel mit die Wärmeübergangsfläche vergrößernden Rippen zu versehen.To improve the heat transfer of the hot combustion gases on the jacket of the evaporator chamber it is finally from EP 0 220 384 A known, this jacket with the heat transfer surface enlarging To provide ribs.

Aufgabe der Erfindung ist es demnach, eine Verdampferkammer zu schaffen, die bei hoher Ausnützung der zugeführten elektrischen Energie für die Verdampfungsaufgabe eine geschützte Unterbringung der elektrischen Widerstandsheizung gewährleistet und auch beim Dauerbetrieb eine gleichmäßige Erwärmung der Innenseite der Verdampferkammer unter Vermeidung von Versottungen ergebenden Überhitzungsstellen ermöglicht sowie bei diesem Dauerbetrieb die Einbringung hinreichend hoher, z. B. in der Größenordnung von 350 °C liegender Erhitzungstemperaturen der Verdampferkammer aus der Verbrennung sichert.The object of the invention is therefore to an evaporator chamber create that with high utilization of the supplied electrical energy for the Evaporation task a protected housing of the electrical resistance heating guaranteed and even during continuous operation Heating the inside of the evaporator chamber while avoiding Overheating spots resulting in sooting enables this as well Continuous operation, the introduction of sufficiently high, z. B. in the order of magnitude of 350 ° C heating temperatures of the evaporator chamber from the Secures combustion.

Die gestellte Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst.The object is achieved by the features of claim 1 solved.

Bei der erfindungsgemäßen Ausführung ist die Elektroheizung durch den geschlossenen Kanal vor äußeren Einflüssen geschützt und gewährleistet eine günstige Erwärmung beider Teile der Verdampferkammer. Durch den die Verdampferkammer mit Abstand umschließenden Isolationsring wird beim Dauerbetrieb der Anteil der zur Erhitzung der Verdampferkammer vom Brennerrohr abzuleitenden heißen Verbrennungsgase verringert und eine Abkühlung dieser Gase an Wärmetauscherflächen eines Kessels od. dgl., in den der Brenner eingebaut wird, weitgehend vermieden. In the embodiment of the invention, the electric heater is by the closed channel protected from external influences and ensures a favorable heating of both parts of the evaporator chamber. Through the evaporator chamber insulation ring enclosing at a distance during continuous operation the proportion of the burner tube used to heat the evaporator chamber hot combustion gases to be discharged are reduced and these cool down Gases on heat exchanger surfaces of a boiler or the like, in which the burner is largely avoided.

Zur Verbesserung des Wärmeüberganges kann der Mantel der Verdampferkammer gemäß Anspruch 2 ausgebildet werden.The jacket of the evaporator chamber can improve the heat transfer be formed according to claim 2.

Die üblicherweise für die Herstellung der Verdampferkammer eingesetzten Materialien, nämlich hitzebeständiger Stahlguß oder spanabhebend bearbeiteter hitzebeständiger Stahl, haben an sich einen relativ geringen Emissionsgrad für Strahlungswärme. Es wird deshalb eine Weiterbildung gemäß Anspruch 3 vorgesehen. Diese Oberflächenbeschichtung kann eine Pulverbeschichtung oder auch eine möglichst dunkle Oxidationsschicht sein.The commonly used for the manufacture of the evaporator chamber Materials, namely heat-resistant cast steel or cutting Machined heat-resistant steel have a relatively low emissivity for radiant heat. It is therefore a continuing education Claim 3 provided. This surface coating can be a powder coating or an oxidation layer that is as dark as possible.
