Description

Die Erfindung betrifft eine Steuerungsvorrichtung für Ölbrenner gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a control device for oil burners according to the preamble of claim 1.

Steuerungsvorrichtungen der obigen Art sind aus dem Stand der Technik hinlänglich bekannt, siehe z.B. US-A-4,162,887 oder CA-A-2 214 228. Derartige Steuerungsvorrichtungen werden auch als Feuerungsautomat bezeichnet.Control devices of the above type are sufficient from the prior art known, see e.g. US-A-4,162,887 or CA-A-2 214 228. Such control devices are also called burner controls designated.

Nach dem Stand der Technik sind die unterschiedlichen Komponenten eines Ölbrenners getrennt - also als Einzelkomponenten - ausgebildet. Zu diesen Einzelkomponenten zählen unter anderem der Feuerungsautomat, ein Ölvorwärmer, ein Zündtransformator und eine Flammenüberwachungs-Einrichtung. Bekannte Feuerungsautomaten steuern den Gesamtablauf der Verbrennung und das Zusammenspiel mit den übrigen Einzelkomponenten, wobei nach dem Stand der Technik in der Regel zumindest der Ölvorwärmer über eine eigene Steuerungskomponente, nämlich über eine Temperaturregelung für ein Heizelement des Ölvorwärmers, verfügt. Hierdurch bedingt ergibt sich der Nachteil einer uneinheitlichen Steuerung bzw. Regelung.According to the state of the art, the different components of an oil burner are separately - that is, as individual components. These individual components include including the burner control, an oil preheater, an ignition transformer and one Flame monitoring device. Known burner controls control the Overall combustion process and interaction with the rest Individual components, according to the prior art usually at least the Oil preheater via its own control component, namely via a Temperature control for a heating element of the oil preheater. Due to this there is the disadvantage of inconsistent control or regulation.

Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zu Grunde, eine Steuerungsvorrichtung zu schaffen, welche eine einheitliche Steuerung bzw. Regelung gewährleistet.Proceeding from this, the present invention is based on the problem, one To create control device, which a uniform control or regulation guaranteed.

Dieses Problem wird durch eine Steuerungsvorrichtung für Ölbrenner mit den Merkmalen des Anspruchs 1 gelöst.This problem is solved by a control device for oil burners with the features of claim 1 solved.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen und der Beschreibung. Nachfolgend wird ein bevorzugtes Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. In der Zeichnung zeigt:

Fig. 1
eine Steuerungsvorrichtung für Ölbrenner nach dem Stand der Technik in Verbindung mit einem bekannten Ölvorwärmer in schematisierter Darstellung; und
Fig. 2
eine erfindungsgemäße Steuerungsvorrichtung für Ölbrenner in Verbindung mit einem Ölvorwärmer ebenfalls in schematisierter Darstellung.
Further advantageous embodiments of the invention result from the subclaims and the description. A preferred exemplary embodiment of the invention is explained in more detail below with reference to the drawing. The drawing shows:
Fig. 1
a control device for oil burners according to the prior art in connection with a known oil preheater in a schematic representation; and
Fig. 2
a control device according to the invention for oil burners in connection with an oil preheater also in a schematic representation.

Fig. 1 zeigt eine Steuerungsvorrichtung 10 für Ölbrenner nach dem Stand der Technik in Verbindung mit einem Ölvorwärmer 11. Die Steuerungsvorrichtung 10 wird auch als Feuerungsautomat bezeichnet. Nach dem Stand der Technik sind die Steuerungsvorrichtung 10 und der Ölvorwärmer 11 funktional getrennt ausgebildet. Demnach wird bei einer Wärmeanforderung das einem nicht-dargestellten Ölbrenner zuzuführende Öl vom Ölvorwärmer 11, nämlich von einem Heizelement 12 desselben, aufgeheizt, bis eine sogenannte Freigabetemperatur erreicht wird. Nach dem Stand der Technik wird das Erreichen der Freigabetemperatur vom Ölvorwärmer 11 selbst überwacht, der hierzu über einen Temperatursensor 13, eine Steuerungskomponente 14 und einen Thermostaten 15 verfügt. Die als Temperaturregelung arbeitende Steuerungskomponente 14 des Ölvorwärmers 11 steuert/regelt das Erreichen der Freigabetemperatur, wobei nach dem Erreichen der Freigabetemperatur der Thermostat 15 - sogenannter Freigabethermostat - schließt und dem Feuerungsautomaten den Befehl zum Programmablauf gibt, also zum Starten der Vorbelüftung, zum Zünden nach erfolgter Vorbelüftung, zur Ventilfreigabe und damit letztendlich zum Starten des Ölbrenners. Bedingt durch die obige funktionale Trennung ergeben sich Uneinheitlichkeiten in der Regelung, die durch die nachfolgend in Verbindung mit Fig. 2 beschriebene erfindungsgemäße Steuerungsvorrichtung vermieden werden können.1 shows a control device 10 for oil burners according to the prior art in Connection with an oil preheater 11. The control device 10 is also called Automatic burner control. According to the state of the art Control device 10 and the oil preheater 11 are functionally separate. Accordingly, when there is a heat request, this becomes an oil burner, not shown Oil to be supplied from the oil preheater 11, namely from a heating element 12 of the same, heated until a so-called release temperature is reached. According to the state of the Technique is reaching the release temperature of the oil preheater 11 itself monitors, for this purpose via a temperature sensor 13, a control component 14 and has a thermostat 15. The one working as temperature control Control component 14 of the oil preheater 11 controls the reaching of Release temperature, the thermostat 15 after reaching the release temperature - so-called release thermostat - closes and the burner control receives the command to Program sequence gives, i.e. to start the pre-ventilation, to ignite after the Pre-ventilation, for valve release and ultimately for starting the oil burner. Due to the functional separation above, there are inconsistencies in the Regulation described by the following in connection with FIG. 2 control device according to the invention can be avoided.

Fig. 2 zeigt die erfindungsgemäße Steuerungsvorrichtung 110 in Verbindung mit einem Ölvorwärmer 111. Erfmdungsgemäß weist die Steuerungsvorrichtung 110 die Steuerungskomponente des Ölvorwärmers 111 in integrierter Bauweise auf. Durch diese Kombination bzw. Integration wird die eigentliche Regelung der Freigabetemperatur des Öls durch die vorhandene Logik des Feuerungsautomaten übernommen. Die im Stand der Technik benötigte separate Steuerungskomponente des Ölvorwärmers entfällt. Gleiches gilt für den im Stand der Technik benötigten Freigabethermostaten. Der Ölvorwärmer 111 benötigt demnach nur noch ein Heizelement 112 und einen Temperatursensor 113, wobei die Meßwerte der Temperatursensors 113 unmittelbar von der erfindungsgemäßen Steuerungsvorrichtung 110 verarbeitet werden. 2 shows the control device 110 according to the invention in connection with a Oil preheater 111. According to the invention, the control device 110 has the Control component of the oil preheater 111 in an integrated design. Through this Combination or integration becomes the actual regulation of the release temperature of the Oil taken over by the existing logic of the burner control. The state of the art Technology required separate control components of the oil preheater are not required. The same applies to the release thermostats required in the prior art. The oil preheater 111 therefore only needs a heating element 112 and a temperature sensor 113, wherein the measured values of the temperature sensor 113 directly from that of the invention Control device 110 are processed.

Im Sinne der vorliegenden Erfindung verfügt der Feuerungsautomat demnach direkt über die aktuellen Meßwerte des Temperatursensors 113. Mit diesem Wissen kann er selbst entscheiden, ob die notwendige Freigabetemperatur erreicht ist oder nicht, und er ist nicht mehr auf einen Thermostaten angewiesen. Hierdurch ergibt sich eine erhebliche Kostenersparnis.For the purposes of the present invention, the burner control therefore has direct the current measured values of the temperature sensor 113. With this knowledge, he can himself decide whether the necessary release temperature has been reached or not and it is not rely more on a thermostat. This results in a significant one Cost savings.

Eine weitere Kostenersparnis ergibt sich dadurch, daß eine nach dem Stand der Technik erforderliche Überbrückung des Freigabethermostaten in der Steuerungsvorrichtung entfallen kann. Diese Funktion ist nach dem Stand der Technik oft notwendig, wenn die Regelung des Ölvorwärmers unzureichend ist und dadurch eventuell der Thermostat wieder öffnen könnte. Da nach der vorliegenden Erfindung die Steuerungsvorrichtung 110 die Öltemperatur unmittelbar kennt, kann der im Stand der Technik erforderliche, jedoch in Fig. 1 nicht dargestellte Schließkontakt entfallen.A further cost saving results from the fact that one according to the prior art required bridging of the release thermostat in the control device can be omitted. According to the state of the art, this function is often necessary if the Control of the oil preheater is inadequate and possibly the thermostat could open again. According to the present invention, since the control device 110 Knows the oil temperature directly, but may be necessary in the prior art 1 are not shown.

Die erfindungsgemäße Steuerungsvorrichtung 110 übernimmt demnach sämtliche Steuerungsfunktionen und/oder Regelungsfunktionen für den Ölvorwärmers 111. Insgesamt ergeben sich daraus folgende Vorteile:

  • a) Die erfindungsgemäße Steuerungsvorrichtung 110 gewährleistet eine einheitliche Regelung.
  • b) Unabhängig von der Durchsatzleistung des Ölbrenners kann die Öl-Temperatur gehalten werden, da der Temperatursensor seine Meßwerte an den Feuerungsautomaten abgibt und dieser bei Bedarf nachregelt. Bei üblichen 2-stufigen Anwendungen führt das Umschalten von einer ersten Stufe auf eine zweite Stufe zu einer Reduzierung der aufgeheizten Öltemperatur aufgrund des höheren Durchsatzes. Die erfindungsgemäße Steuerungsvorrichtung 110 regelt nach, wodurch beim Hochschalten die geforderte Öltemperatur kurzfristig erreicht wird. So kann der Ölbrenner in beiden Stufen mit annähernd gleicher vorgewärmter Öltemperatur betrieben werden, wodurch eine verbesserte Zerstäubung des Öls und damit letztendlich eine verbesserte Verbrennung gewährleistet ist.
  • c) Die Starttemperatur bzw. Freigabetemperatur ist frei wählbar und nicht mehr durch den Thermostaten des Ölvorwärmers 111 vorgegeben. Der Thermostat entfällt.
  • d) Die elektrische Überbrückung des Thermostaten entfällt. Sie kann mit Hilfe von Software realisiert werden.
  • e) Sollte im Betrieb während einer bestimmten Zeitspanne keine Wärmeanforderung vorliegen, da z.B. ein Temperaturanstieg aufgrund einer Durchsatzverringerung erfolgt, so prüft die erfindungsgemäße Steuerungsvorrichtung 110 frühzeitig eine Störabschaltung und führt sie gegebenenfalls durch bevor eine Düse des Ölbrenners oder eine Mischeinrichtung desselben verkokst ist. Dies kommt einem integriertem Frühwarnsystem gleich, wodurch die Standzeit des Ölbrenners erhöht wird.
    • The control device 110 according to the invention accordingly takes over all control functions and / or regulation functions for the oil preheater 111. Overall, the following advantages result:
  • a) The control device 110 according to the invention ensures uniform regulation.
  • b) Irrespective of the throughput of the oil burner, the oil temperature can be maintained since the temperature sensor outputs its measured values to the automatic burner control unit and adjusts it if necessary. In conventional 2-stage applications, switching from a first stage to a second stage leads to a reduction in the heated oil temperature due to the higher throughput. The control device 110 according to the invention adjusts, as a result of which the required oil temperature is reached briefly when shifting up. Thus, the oil burner can be operated in both stages with approximately the same preheated oil temperature, whereby an improved atomization of the oil and ultimately an improved combustion is guaranteed.
  • c) The start temperature or release temperature can be freely selected and is no longer specified by the thermostat of the oil preheater 111. The thermostat is omitted.
  • d) There is no electrical bridging of the thermostat. It can be implemented using software.
  • e) If there is no heat demand during operation for a certain period of time, for example because there is a rise in temperature due to a reduction in throughput, the control device 110 according to the invention checks for a fault lock-out at an early stage and carries it out, if necessary, before a nozzle of the oil burner or a mixing device is carbonized. This is equivalent to an integrated early warning system, which increases the service life of the oil burner.

    • Es liegt weiterhin im Sinne der Erfindung, daß die Steuerungsvorrichtung 110 des weiteren Steuerungskomponenten eines Zündtransformators und/oder einer Flammenüberwachungs-Einrichtung in integrierter Bauweise aufweisen kann. In diesem Fall übernimmt die Steuerungsvorrichtung 110 sämtliche Steuerungsfunktionen und/oder Regelungsfunktionen für den Ölvorwärmer 111 sowie den Zündtransformator und/oder die Flammenüberwachungs-Einrichtung. Hierdurch wird ein hoher Integrationsgrad erzielt, der vor allem unter Kostenerwägungen günstig ist. It is further within the meaning of the invention that the control device 110 further Control components of an ignition transformer and / or a flame monitoring device can have in an integrated design. In this case the Control device 110 all control functions and / or regulation functions for the oil preheater 111 and the ignition transformer and / or the flame monitoring device. As a result, a high degree of integration is achieved is cheap especially considering cost considerations.
