Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Verbrennen von festen Brennstoffen, insbesondere einen Kamin- oder Kachelofen, Kamineinsatz oder dergleichen, mit einem an einen Verbrennungsluftanschluss sowie eine Abgasführung angeschlossenen Brennraum, wobei der Verbrennungsluftanschluss zur Zuführung von primärer und sekundärer Verbrennungsluft in den Brennraum ausgebildet, eine Einrichtung zur Erfassung von Betriebsparametern des Verbrennungsprozesses vorgesehen und die Verbrennungsluftzufuhr in Abhängigkeit der erfassten Betriebsparameter des Verbrennungsprozesses veränderbar ist.The invention relates to a device for burning solid fuels, in particular a fireplace or tiled stove, fireplace insert or the like, with a connected to a combustion air connection and an exhaust gas combustion chamber, wherein the combustion air connection for supplying primary and secondary combustion air formed in the combustion chamber, a device for detecting operating parameters of the combustion process provided and the combustion air supply in response to the detected operating parameters of the combustion process is variable.
Feuerungsanlagen wie Kaminanlagen, Kachelöfen, Kaminöfen oder dergleichen werden meist chargenweise mit Brennstoffen wie Holz in stückiger oder gepresster Form, Stroh oder anderen nachwachsenden Brennstoffen oder auch mit Kohlebrennstoffen befeuert. Mit Biomasse, also vorwiegend mit Holz, betriebene Feuerungsanlagen leisten den größten Beitrag zur Nutzung regenerativer Energien. Aus diesem Grunde und auch aufgrund der damit erreichbaren Verbesserung der Wärmeversorgungssicherheit in Privathaushalten erfreuen sich solche Feuerungsanlagen bzw. Vorrichtung zum Verbrennen von festen Brennstoffen zunehmender Beliebtheit.Firing systems such as chimney systems, tiled stoves, stoves or the like are usually fired in batches with fuels such as wood in lumpy or pressed form, straw or other renewable fuels or coal fuels. Firing systems powered by biomass, ie mainly wood, make the greatest contribution to the use of renewable energies. Out For this reason, and also because of the achievable improvement of the heat supply security in private households, such furnaces or apparatus for burning solid fuels are becoming increasingly popular.
In vielen Anwendungsfällen werden solche Vorrichtungen als Einzelfeuerstätten vorgesehen, bei denen die Verbrennung ohne Gebläseunterstützung abläuft und die Verbrennungsluftzufuhr und die Abgasableitung mithilfe des natürlichen Schornsteinzuges bewerkstelligt wird. Solche Feuerstätten können vorteilhafterweise ohne elektrische Hilfsenergie betrieben werden.In many applications, such devices are provided as a single fireplaces, where the combustion takes place without fan assist and the combustion air supply and the exhaust gas discharge is accomplished by means of the natural chimney draft. Such fireplaces can advantageously be operated without auxiliary electric power.
Insbesondere chargenweise beschickte Vorrichtungen zum Verbrennen von festen Brennstoffen geben die Wärme üblicherweise nicht gleichmäßig über eine längere Zeit ab, sondern erzeugen nach einer Anbrennphase mit eher schwacher Wärmeabgabe während einer begrenzten Zeitspanne eine hohe Wärmemenge. Dieser Phase folgt eine Ausbrandphase, während der die Wärmeabgabe allmählich abnimmt. Entsprechend der Verbrennungsgeschwindigkeit und damit entsprechend der Wärmeerzeugung kann die Temperatur im Brennstoffglutbett variieren und darüber hinaus auch die Abgastemperatur. Die Glutbetttemperatur ist allerdings ein entscheidender Faktor für die Verbrennungsqualität. Zu geringe Temperaturen im Gutbett führen zu unvollständiger Verbrennung und damit zu erhöhten Emissionen an Kohlenmonoxid und verbrannten Kohlewasserstoffen oder auch Ruß. Neben der schädlichen Wirkung solcher Abgase tritt als weiterer unerwünschter Effekt die unvollständige Ausnutzung des Brennstoffes hinzu. Zwar sind hohe Verbrennungstemperaturen für eine vollständige Verbrennung und damit optimale Ausnutzung der im Brennstoff gespeicherten chemischen Energie vorteilhaft. Allerdings führen zu hohe Verbrennungstemperaturen zu thermischer Stickoxidbildung, d.h. zu einer Umwandlung des in der Verbrennungsluft enthaltenen Stickstoffs zu Stickstoffoxiden. Um diesen Schadstoff zu vermeiden, sollte die Glutbetttemperatur einen bestimmten Maximalwert nicht überschreiten.In particular, batch-fed solid fuel burning devices usually do not dissipate the heat evenly over a long period of time, but produce a large amount of heat after a firing phase of rather low heat release for a limited period of time. This phase is followed by a burnout phase during which the heat release gradually decreases. According to the combustion rate and thus according to the heat generation, the temperature in the fuel bed can vary, and beyond that also the exhaust gas temperature. The temperature of the ember bed, however, is a decisive factor for the quality of combustion. Too low temperatures in the good bed lead to incomplete combustion and thus to increased emissions of carbon monoxide and burned hydrocarbons or soot. In addition to the harmful effect of such gases occurs as a further undesirable effect of the incomplete utilization of the fuel added. Although high combustion temperatures are for one complete combustion and thus optimal utilization of the chemical energy stored in the fuel advantageous. However, too high combustion temperatures lead to thermal nitrogen oxide formation, ie to a conversion of the nitrogen contained in the combustion air into nitrogen oxides. To avoid this pollutant, the ember bed temperature should not exceed a certain maximum value.
Der Verlauf der Abgastemperatur spiegelt den Fortschritt des Abbrandes wieder. Andererseits ist die erhöhte Temperatur des Abgases ursächlich für den Schomsteinzug und stellt damit den Antrieb für die Verbrennungsluft- und Abgasförderung zur Verfügung. Nach dem Anbrennen ist es wichtig, möglichst rasch ausreichend hohe Temperaturen zu erreichen. Dies ist einerseits wichtig, um die Startphase mit geringen Verbrennungstemperaturen und damit die Gefahr einer unvollständigen Verbrennung möglichst gering zu halten. Andererseits stellt sich erst bei ausreichend hoher Abgastemperatur ein für eine gute Verbrennung ausreichender Schornsteinzug ein.The course of the exhaust gas temperature reflects the progress of the combustion. On the other hand, the increased temperature of the exhaust gas is the cause of the Schomsteinzug and thus provides the drive for the combustion air and exhaust gas production available. After firing, it is important to reach sufficiently high temperatures as quickly as possible. On the one hand, this is important in order to keep the starting phase with low combustion temperatures and thus the risk of incomplete combustion as low as possible. On the other hand, only at a sufficiently high exhaust gas temperature is sufficient for a good combustion chimney draft.
In der Hauptbrandphase steigen die Abgastemperaturen je nach Bauweise der Feuerstätte erheblich an. Dadurch wird die Luftzufuhr in den Brennraum weiter erhöht und führt zu einer noch schnelleren Verbrennung mit entsprechend noch höherer Wärmeerzeugung. Auf diese Weise können Verhältnisse entstehen, die zu einem immer stärkeren Entfachen des Feuers führen, wodurch der Brennstoff unter kurzzeitig sehr hoher Wärmeabgabe in kurzer Zeit abbrennt.In the main fire phase, the exhaust gas temperatures rise significantly depending on the design of the fireplace. As a result, the air supply is further increased in the combustion chamber and leads to an even faster combustion with correspondingly even higher heat generation. In this way, conditions can arise, which lead to an ever stronger ignition of the fire, causing the fuel burns under briefly very high heat release in a short time.
Um auf diese verschiedenen Verbrennungsphasen einzuwirken, wäre es erforderlich, dass eine Bedienperson auf den Verbrennungsprozess in geeigneter Weise einwirkt, was jedoch bei bislang bekannten Feuerungsanlagen nicht in optimaler Weise durchgeführt werden kann. Bei bekannten Vorrichtungen zum Verbrennen von festen Brennstoffen sind in der Regel Einstellmöglichkeiten vorgesehen, um den Querschnitt der Verbrennungsluftzuführung zu verkleinern. Darüber hinaus ist bekannt eine gestufte Verbrennungsluftzufuhr vorgesehen, mit denen ein Teil der Verbrennungsluft als Primärluft direkt in das Glutbett eingedüst wird und ein anderer Teil als Sekundärluft oberhalb des Glutbettes zugeführt wird, um diese Sekundärluft mit den Verbrennungsgasen zu vermischen und dadurch eine vollständige Nachverbrennung sowie eine verbesserte Verbrennungsgüte zu erreichen, wodurch auch die Schadstoffemission zu verringern sind.In order to act on these different combustion phases, it would be necessary for an operator to have an appropriate effect on the combustion process, which, however, can not be optimally performed in previously known combustion plants. In known devices for burning solid fuels adjustment options are provided in the rule to reduce the cross section of the combustion air supply. In addition, a stepped combustion air supply is known, with which a part of the combustion air is injected as primary air directly into the ember bed and another part is supplied as secondary air above the ember bed to mix this secondary air with the combustion gases and thereby a complete afterburning and a to achieve improved combustion quality, which also reduce the emission of pollutants.
Solche Einstelleinrichtungen werden üblicherweise von Hand betätigt und sind somit während des Abbrandes von der Bedienperson jeweils passend zur Abbrandphase einzustellen. Dies ist von einer ungeübten Bedienperson jedoch nicht zu vollziehen.Such adjusting devices are usually operated by hand and are thus adjusted during the burn-off by the operator in each case suitable for the burning-off phase. However, this can not be done by an untrained operator.
Es ist Aufgabe der vorliegenden Erfindung, eine Vorrichtung zum Verbrennen von festen Brennstoffen zur Verfügung zu stellen, mit der eine Vergleichmäßigung des Verbrennungsvorganges während der Verbrennung vorzusehen ist.It is an object of the present invention to provide a device for burning solid fuels, with which a homogenization of the combustion process during combustion is provided.
Zur Lösung dieser Aufgabe zeichnet sich die Vorrichtung der eingangs genannten Art dadurch aus, dass die Einrichtung zur Erfassung von Betriebsparametern des Verbrennungsprozesses als Steuermodul ausgebildet ist und mit einer motorisch betätigbaren, von einem Steuermodul regelbaren Einstellvorrichtung zur Veränderung der Verbrennungsluftzufuhr verbunden ist und dass die primäre und die sekundäre Verbrennungsluftzufuhr jeweils in Abhängigkeit der erfassten Betriebsparameter des Verbrennungsprozesses über das Steuermodul von der Einstellvorrichtung steuerbar sind.To solve this problem, the device of the type mentioned is characterized in that the means for detecting operating parameters of the combustion process is designed as a control module and with a motor operable, controllable by a control module adjusting device for changing the combustion air supply is connected and that the primary and the secondary combustion air supply in each case depending on the detected operating parameters of the combustion process via the control module of the adjusting device are controllable.
Damit ist eine Vorrichtung zum Verbrennen von festen Brennstoffen zur Verfügung gestellt, mit der sowohl die Verbrennungsqualität als auch die Schadstoffemission und die Ausnutzung des Brennstoffes wesentlich zu verbessern sind, indem der Betreiber nicht mehr manuell Einstellungen an der Feuerungsstätte vornehmen muss, sondern über die Einrichtung zur Erfassung von Betriebsparametern verbrennungsspezifische Werte wie die Abgastemperatur und/oder die Glutbetttemperatur und/oder das stöchiometrische Luftverhältnis im Abgas oder sonstige Werte zu ermitteln und für eine Steuerung der motorisch betätigbaren Einstellvorrichtung von dem Steuermodul im Automatikbetrieb umzusetzen sind. Hierbei können entsprechende Sollwerte vorgegeben werden, die mit den von der Einrichtung zur Erfassung von Betriebsparametern gelieferten Ist-Werten verglichen werden, so dass die Verbrennungsluftzufuhr, und zwar sowohl die primäre als auch die sekundäre entsprechend gesteuert werden kann.Thus, a device for burning solid fuel is provided, with the combustion quality as well as the pollutant emissions and the utilization of the fuel are to be substantially improved by the operator no longer has to make manual settings on the furnace, but on the device for Detection of operating parameters combustion-specific values such as the exhaust gas temperature and / or the Emberbetttemperatur and / or the stoichiometric air ratio in the exhaust gas or other values to be determined and implemented for control of the motorized adjustment of the control module in automatic mode. In this case, corresponding desired values can be preset, which are compared with the actual values supplied by the device for detecting operating parameters, so that the combustion air supply, both the primary and the secondary, can be correspondingly controlled.
Darüber hinaus sieht die Erfindung vor, dass zusätzlich ein manuell bedienbarer Stellhebel vorgesehen ist, mit dem auf herkömmliche Art und Weise der Benutzer auf den Verbrennungsvorgang Einwirkung nehmen kann, indem er die Einstellvorrichtung manuell betätigt. Dies ist insbesondere auch dann wichtig, wenn beispielsweise ein Stromausfall vorliegt, wonach dann mittels des manuellen Stellhebels die Verbrennungsluftzufuhr gesteuert werden kann. Im automatischen Betrieb dient der Stellhebel als Anzeigevorrichtung für die jeweilige Einstellung der Verbrennungsluft und ermöglicht dem Betreiber somit die Funktion der automatischen Verbrennungslufteinstellung zu überwachen, Es ist zudem möglich, für die automatische Verbrennungslufteinstellung z.B. auch das Öffnen einer Brennraumtür zu berücksichtigen oder auch zu verarbeiten, dass Brennstoff nachgelegt wird.In addition, the invention provides that in addition a manually operable lever is provided with the conventional manner, the user can act on the combustion process by manually operating the adjustment. This is especially important if, for example there is a power failure, after which then the combustion air supply can be controlled by means of the manual control lever. In automatic operation, the lever serves as a display device for the respective adjustment of the combustion air and thus allows the operator to monitor the function of the automatic combustion air adjustment, It is also possible for the automatic combustion air adjustment, for example, to consider the opening of a combustion chamber door or process that Fuel is refilled.
Insbesondere wird durch die Erfindung der Benutzerkomfort erheblich verbessert. Eine lange gleichmäßige Wärmeabgabe kann sichergestellt werden und darüber hinaus kann eine erhebliche Wirkungsgradverbesserung erreicht werden, so dass eine bessere Wirtschaftlichkeit vorliegt, eine erhöhte Schadstoffemission vermieden wird und darüber hinaus auch Bedienfehler ausgeschlossen werden können, die zu einer Überhitzung, einer Scheibenverrußung, einer Schornsteinversottung, einer Brennstoffverschwendung und zu hohen Emissionen führen können.In particular, the invention improves user comfort considerably. A long uniform heat release can be ensured and beyond a significant improvement in efficiency can be achieved, so that there is better efficiency, an increased pollutant emissions is avoided and also operator errors can be excluded, leading to overheating, a Scheibentrrußung, a chimney scoop, a Fuel waste and lead to high emissions.

Nicht näher dargestellt sind magnetische Kupplungen und ein Permanentmagnet, die so zu betätigen sind, wie dies in den Ansprüchen 6 und 7 angegeben ist. Um verschiedene verbrennungsspezifische Parameter zu erfassen, ist ein Abgastemperatursensor 14, ein Abgassensor 15 (z.B. eine Lambda-Sonde) und ein Glutbetttemperatursensor 16 sowie ein Türsensor 25 vorgesehen. Diese sind alle mit dem Steuermodul 17, dass die Einrichtung zur Erfassung von Betriebsparametern des Verbrennungsprozesses beinhaltet, verbunden.Not shown in detail are magnetic couplings and a permanent magnet, which are to be operated as indicated in
Im Rahmen der Erfindung ist es selbstverständlich auch möglich, auf einzelne solcher Sensoren zu verzichten, und auch weniger Betriebsparameter zu verarbeiten.In the context of the invention, it is of course also possible to dispense with individual such sensors, and also to process less operating parameters.
Aufgrund der erfassten Betriebsparameter des Verbrennungsprozesses wird von dem Steuermodul anhand vorgebbarer Sollwerte die Verbrennungsluftzufuhr über die Einstellvorrichtung 8 gesteuert, und zwar sowohl für die Zuführung von primärer Verbrennungsluft als auch für die Zuführung von sekundärer Verbrennungsluft für die Nachverbrennung, so dass insgesamt ein vergleichmäßigter Verbrennungsprozess darzustellen ist, ohne dass der Benutzer auf die Verbrennungsluftzufuhr einwirken kann, womit die wohlbekannten Risiken einer Fehlbedienung ausgeschlossen werden können. Im Störfall kann er selbstverständlich über den Stellhebel die Verbrennungsluftzufuhr dann seinerseits verändern. Ebenfalls ist es möglich, über das Steuermodul einen Betriebszustand auf den manuellen Betrieb umzustellen.On the basis of the detected operating parameters of the combustion process, the combustion air supply is controlled by the control module on the basis of predefinable setpoint values via the
