Definitions
- the invention relates to a heating boiler for the combustion of solid fuels, according to the preamble of the protection claim. 1
- Boilers essentially consist of a heating medium-leading boiler body made of cast-iron boiler elements or welded steel sheets. This includes a filling space for fuel with an upper or side filling opening, a combustion grate with an ash box arranged thereunder. In this case, a pyrolytic combustion takes place above the combustion grate and thus at the bottom of the fuel quantity in the filling space. Fuel thus continuously slips by the weight from above.
- Solid fuel boilers for firewood or pellet boilers are known for burning solid fuels.
- the door serves only as a front or top closure and access, and in the second case it receives a corresponding pellet burner.
- Special solid fuel boilers with firing grates and in each case at least one ash box located underneath are widespread.
- the state of charge of the fuel is not recorded in currently used firewood boilers, and an estimate of the fuel consumption is based on observation or empirical values only.
- the information about the amount loaded and the fuel consumption over time can not be determined.
- an operator may therefore seek out the boiler in excessively short time intervals and deposit fuel, which may lead to overheating of the connected heat consumer circuit.
- there may be a loss of comfort for a user if there is too little fuel in the filling space and it burns empty. Any intervention on the fuel load will usually lead, albeit only for a short time, to higher exhaust emissions.
- the invention is therefore based on the object to optimize the operation and operation of boilers and stoves for the combustion of solid fuels.
- An inventive boiler is characterized by at least one arranged in the upper region of the filling space distance sensor for non-contact detection of the fuel level in the filling space.
- the determination of the fuel level and the time profile of the fuel level is realized by a distance sensor generates a signal for a Brownstandsauswak- and display device and / or a control device.
- the at least one distance sensor detects the direction and / or transit time of an actively emitted, on the fuel, especially at the top, reflected Signal.
- several distance sensors used in parallel can detect the level even better.
- the at least one distance sensor operates capacitively, inductively or by means of a parallax and / or a stereo image of an electronic camera.
- the actively emitted measuring beams of a distance sensor include light, infrared radiation, radio waves, microwaves, terahertz radiation or ultrasound. If a capacitive distance sensor is used, it works with an electric alternating field.
- the filling level evaluation and display device has a display unit with an optical, mechanical and / or acoustic signal device, which responds to a necessary filling of the filling space with fuel.
- This arrangement can be mounted on a boiler independently of an existing control device, for example, clearly visible on the boiler or even in a room in the residence area of a user.
- the filling level evaluation and display device is integrated in a display unit of a control device for the heating boiler, so that the control device processes the signal generated by the at least one distance sensor.
- the invention ensures lower emission levels, in particular with regard to unburned hydrocarbons, such as CO and NO x, during firewood combustion. This is achieved by the fact that with the knowledge about the level of the fuel as well as over time course of the fuel supply in the filling space always an optimal operating point in terms of efficiency and emissions can be approached. Thus, according to the invention, a further criterion for the precise, demand-driven activation of an exhaust gas and / or combustion air blower is created. Critical operating phases, such as hollow fires, can be determined by the fuel consumption over time.
- a conveyor for fuels can be controlled, which supplies the filling space accordingly.
- the operator can be proposed on the basis of a heat balance optimal operation, so that it is supported in terms of economic and environmental performance.
- the drawing illustrates an embodiment of the invention and shows in a single figure schematically a vertical section through a solid fuel fired boiler.
- the boiler consists essentially of a heating medium-carrying boiler body 1, a filling chamber 2 for fuel 3 with an upper filling 4, a grate 5 with an ash box 6 arranged below, a Schugasaustrittsö réelle 7 in a not shown, downstream combustion chamber with a subsequent heat exchanger for the heating gas and a control device 8.
- three distance sensors 9 for contactless detection of the fuel level in the filling space 2 are arranged, which detect the direction and / or transit time of an actively emitted signal reflected at the fuel 3 and generate a signal for a filling level evaluation and display device , which is integrated in the control device 8.

Abstract
Description
Die Erfindung betrifft einen Heizkessel zur Verbrennung von festen Brennstoffen, gemäß dem Oberbegriff des Schutzanspruches 1.The invention relates to a heating boiler for the combustion of solid fuels, according to the preamble of the protection claim. 1
Heizkessel bestehen im Wesentlichen aus einem Heizmedium führenden Kesselkörper aus gusseisernen Kesselgliedern oder aus verschweißten Stahlblechen. Dieser beinhaltet einem Füllraum für Brennstoff mit einer oberen oder seitlichen Befüllöffnung, einem Brennrost mit einem darunter angeordnetem Aschekasten. Dabei erfolgt eine pyrolytische Verbrennung oberhalb des Brennrostes und somit an der Unterseite der Brennstoffmenge im Füllraum. Brennstoff rutscht somit laufend durch das Eigengewicht von oben her nach.Boilers essentially consist of a heating medium-leading boiler body made of cast-iron boiler elements or welded steel sheets. This includes a filling space for fuel with an upper or side filling opening, a combustion grate with an ash box arranged thereunder. In this case, a pyrolytic combustion takes place above the combustion grate and thus at the bottom of the fuel quantity in the filling space. Fuel thus continuously slips by the weight from above.
Über eine Heizgasaustrittsöffnung gelangen die Pyrolysegase in eine nachgeschaltete Brennkammer. Die hier entstehenden Verbrennungstemperaturen werden in einem sich anschließenden Wärmetauscher abgebaut, indem die Wärme an das umgebende Heizmedium abgegeben wird. Danach strömen die Heizgase zu einem Abgasstutzen. Weiterhin übernimmt eine Regeleinrichtung die Steuerung des Verbrennungsablaufs und diverse Sicherheitsfunktionen.About a Heizgasaustrittsöffnung reach the pyrolysis gases in a downstream combustion chamber. The resulting combustion temperatures are reduced in a subsequent heat exchanger by the heat is released to the surrounding heating medium. Thereafter, the hot gases flow to an exhaust pipe. Furthermore, a control device takes over the control of the combustion process and various safety functions.
Zur Verbrennung von festen Brennstoffen sind so genannte Feststoffkessel für Scheitholz oder Pelletkessel bekannt. Im ersten Fall dient die Tür lediglich als vorderer oder oberer Abschluss und Zugangsmöglichkeit, und im zweiten Fall nimmt sie einen entsprechenden Pelletbrenner auf. Verbreitet sind spezielle Feststoffkessel mit Feuerungsrosten und jeweils mindestens einem darunter angeordneten Aschekasten.Solid fuel boilers for firewood or pellet boilers are known for burning solid fuels. In the first case, the door serves only as a front or top closure and access, and in the second case it receives a corresponding pellet burner. Special solid fuel boilers with firing grates and in each case at least one ash box located underneath are widespread.
Eine automatische Brennstoffzufuhr gehört für Feststoffverbrennungseinrichtungen, wie Heizkessel und Öfen, zum Stand der Technik. Besonders bei Pellet- und Hackschnitzelfeuerung sind lange Betriebszeiten ohne Bedienung möglich. Sogar eine gewichtsgesteuerte Nachführung einer Vielfalt von Festbrennstoffen in eine Brennkammer ist aus der
Beim Verbrennen von festen Brennstoffen entstehen Asche und Rußpartikel in größeren Mengen und gelangen in den zugeordneten Aschekasten. Daher ist das regelmäßige Entfernen von Asche und Rußpartikeln wichtig. Die Reinigungsintervalle variieren relativ stark ergeben sich aus der Art des Brennstoffes, der Heizkesselgeometrie, der Betriebshäufigkeit und des Brenners. Daher ist es für einen Betreiber einer derartigen Feststoffverbrennungseinrichtung relativ schwer einzuordnen, wann genau eine Reinigung erforderlich ist. Dies hat einen erhöhten Aufwand zur Folge, das heißt einerseits wird eventuell zu oft die Aschelade kontrolliert oder gereinigt und andererseits kann eine Reinigung übersehen werden, so dass dann eventuell zu starke Ablagerungen die Funktionsfähigkeit beeinträchtigen.When burning solid fuels ash and soot particles are produced in larger quantities and reach the assigned ash box. Therefore, the regular removal of ash and soot particles is important. The cleaning intervals vary relatively strongly depending on the type of fuel, the boiler geometry, the operating frequency and the burner. Therefore, it is relatively difficult for an operator of such a solid combustion device to determine when exactly a cleaning is required. This has an increased effort result, that is, on the one hand may be too often controlled the ash or cleaned and on the other hand, a cleaning can be overlooked, so that then possibly excessive deposits affect the functionality.
Genauso wird bei derzeitig eingesetzten Scheitholzkesseln der Ladezustand des Brennstoffes nicht erfasst und auch eine Abschätzung des Brennstoffverbrauchs basiert nur auf Beobachtung bzw. auf Erfahrungswerten. Die Information über die eingelegte Menge sowie der zeitliche Brennstoffverbrauch können somit nicht ermittelt werden. Ein Betreiber sucht daher einerseits möglicherweise in zu kurzen Zeitintervallen den Heizkessel auf und legt Brennstoff nach, was eventuell zu einem Überheizen des angeschlossenen Wärmeverbraucherkreislaufes führt. Anderseits kommt es möglicherweise zu Komforteinbußen für einen Nutzer, wenn zu wenig Brennstoff im Füllraum ist und dieser leer brennt. Jeder Eingriff zur Brennstoffbeladung führt in der Regel, wenn auch nur kurzzeitig, zu stärkeren Abgasemissionen.In the same way, the state of charge of the fuel is not recorded in currently used firewood boilers, and an estimate of the fuel consumption is based on observation or empirical values only. The information about the amount loaded and the fuel consumption over time can not be determined. On the one hand, an operator may therefore seek out the boiler in excessively short time intervals and deposit fuel, which may lead to overheating of the connected heat consumer circuit. On the other hand, there may be a loss of comfort for a user, if there is too little fuel in the filling space and it burns empty. Any intervention on the fuel load will usually lead, albeit only for a short time, to higher exhaust emissions.
Der Erfindung liegt daher die Aufgabe zu Grunde, den Betrieb und die Bedienung von Heizkesseln und Öfen zur Verbrennung von festen Brennstoffen zu optimieren.The invention is therefore based on the object to optimize the operation and operation of boilers and stoves for the combustion of solid fuels.
Erfindungsgemäß wurde dies mit den Merkmalen des Schutzanspruches 1 gelöst. Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen.This has been achieved with the features of the
Gekennzeichnet ist ein erfindungsgemäßer Heizkessel durch mindestens einen im oberen Bereich des Füllraumes angeordneten Abstandssensor zur berührungslosen Erfassung des Brennstoff-Füllstandes im Füllraum. Mit dem mindestens einen Abstandssensor wird die Ermittlung des Brennstoff-Füllstandes sowie des zeitlichen Verlaufs des Brennstoff-Füllstandes realisiert, indem ein Abstandssensor ein Signal für eine Füllstandsauswerte- und -anzeigevorrichtung und/oder eine Regeleinrichtung generiert.An inventive boiler is characterized by at least one arranged in the upper region of the filling space distance sensor for non-contact detection of the fuel level in the filling space. With the at least one distance sensor, the determination of the fuel level and the time profile of the fuel level is realized by a distance sensor generates a signal for a Füllstandsauswerte- and display device and / or a control device.
Vorteilhafterweise detektiert der mindestens eine Abstandssensor die Richtung und/oder Laufzeit eines aktiv ausgesandten, am Brennstoff, speziell an dessen Oberseite, reflektierten Signals. Somit können, je nach Füllraumgeometrie und eingesetztem Brennstoff, mehrere parallel eingesetzte Abstandssensoren den Füllstand noch besser erfassen.Advantageously, the at least one distance sensor detects the direction and / or transit time of an actively emitted, on the fuel, especially at the top, reflected Signal. Thus, depending on the geometry of the filling space and the fuel used, several distance sensors used in parallel can detect the level even better.
In bevorzugten Ausführungsformen arbeitet daher der mindestens eine Abstandssensor kapazitiv, induktiv oder mittels einer Parallaxe und/oder eines Stereobildes einer elektronischen Kamera. Dabei umfassen die aktiv ausgesandten Messstrahlen eines Abstandssensors Licht, Infrarotstrahlung, Radiowellen, Mikrowellen, Terahertzstrahlung oder Ultraschall. Wird ein kapazitiver Abstandssensor eingesetzt, so arbeitet dieser mit einem elek-trischen Wechselfeld.In preferred embodiments, therefore, the at least one distance sensor operates capacitively, inductively or by means of a parallax and / or a stereo image of an electronic camera. The actively emitted measuring beams of a distance sensor include light, infrared radiation, radio waves, microwaves, terahertz radiation or ultrasound. If a capacitive distance sensor is used, it works with an electric alternating field.
Weiterhin weist die Füllstandsauswerte- und -anzeigevorrichtung eine Anzeigeeinheit mit einer optischen, mechanischen und/oder akustischen Signaleinrichtung auf, welche bei einer notwendigen Befüllung des Füllraumes mit Brennstoff anspricht. Diese Anordnung kann unabhängig von einer vorhandenen Regeleinrichtung an einem Heizkessel montiert werden, beispielsweise gut sichtbar am Heizkessel oder sogar in einem Raum im Aufenthaltsbereich eines Nutzers.Furthermore, the filling level evaluation and display device has a display unit with an optical, mechanical and / or acoustic signal device, which responds to a necessary filling of the filling space with fuel. This arrangement can be mounted on a boiler independently of an existing control device, for example, clearly visible on the boiler or even in a room in the residence area of a user.
Alternativ oder ergänzend dazu ist in einer vorteilhaften Ausführungsform die Füllstandsauswerte- und -anzeigevorrichtung in eine Anzeigeeinheit einer Regeleinrichtung für den Heizkessel integriert, so dass die Regeleinrichtung das von dem mindestens einen Abstandssensor generierte Signal verarbeitet.Alternatively or additionally, in an advantageous embodiment, the filling level evaluation and display device is integrated in a display unit of a control device for the heating boiler, so that the control device processes the signal generated by the at least one distance sensor.
Mit der erfindungsgemäßen Anordnung werden Betrieb und Bedienung eines Heizkessels oder Ofens zur Verbrennung von festen Brennstoffen optimiert. Das regelmäßig erforderliche Befüllen, aber auch das vom Brennstoffdurchsatz abhängige regelmäßig erforderliche Entleeren des Aschekastens, wird vereinfacht, weil einem Bediener genau der richtige Zeitpunkt für einen Eingriff in den Heizkesselbetrieb signalisiert wird. Daher muss die Befüllöffnung nur noch bei Notwendigkeit, und somit in größeren Zeitintervallen als bisher, geöffnet werden. Die Verschmutzungsgefahr im Aufstellraum minimiert sich dadurch natürlich auch. Generell wird die Bedienungsfreundlichkeit deutlich erhöht, weil für die Bedienung mit der erfindungsgemäßen Funktion keine besonderen Heizgerätekenntnisse erforderlich sind und das Signal auch nicht speziell eingewiesenen Personen eindeutig ist. Beispielsweise kann ein Klartext zum Befüllen auffordern. Diese Meldung wird dann gelöscht, wenn ein manueller Eingriff am Heizkessel oder über den Füllstand die ergänzte Brennstoffmenge erkannt wird.With the arrangement according to the invention, operation and operation of a boiler or oven are optimized for the combustion of solid fuels. The regularly required filling, but also the fuel throughput dependent regularly required emptying of the ash box, is simplified because an operator is signaled exactly the right time for an intervention in the boiler operation. Therefore, the filling opening must be opened only when necessary, and thus in larger time intervals than before. Of course, the risk of contamination in the installation room is also minimized. In general, the ease of use is significantly increased, because no special Heizgerätekenntnisse are required for operation with the function of the invention and the signal is not specifically trained persons clearly. For example, a clear text may ask for filling. This message is cleared when a manual intervention on the boiler or via the level of the supplemented fuel quantity is detected.
Mit der Erfindung werden niedrigere Emissionswerte, insbesondere hinsichtlich unverbrannter Kohlenwasserstoffe, wie CO und NOx, bei der Scheitholzverbrennung gewährleistet. Dies wird dadurch erreicht, dass mit dem Kenntnisstand über den Füllstand des Brennstoffes als auch über zeitlichen Verlauf des Brennstoffvorrats im Füllraum stets ein optimaler Betriebspunkt hinsichtlich Wirkungsgrad und Emissionen angefahren werden kann. Es wird somit erfindungsgemäß ein weiteres Kriterium zum genauen, bedarfsgerechten Ansteuern eines Abgas- und/oder Verbrennungsluftgebläses geschaffen. Kritische Betriebsphasen, wie zum Beispiel Hohlbrände, können über den zeitlichen Brennstoffverbrauch ermittelt werden.The invention ensures lower emission levels, in particular with regard to unburned hydrocarbons, such as CO and NO x, during firewood combustion. This is achieved by the fact that with the knowledge about the level of the fuel as well as over time course of the fuel supply in the filling space always an optimal operating point in terms of efficiency and emissions can be approached. Thus, according to the invention, a further criterion for the precise, demand-driven activation of an exhaust gas and / or combustion air blower is created. Critical operating phases, such as hollow fires, can be determined by the fuel consumption over time.
Außerdem kann mit den erfindungsgemäßen Maßnahmen eine Fördereinrichtung für Brennstoffe angesteuert werden, die den Füllraum entsprechend versorgt. Durch die Ermittlung des Brennstoffladezustands kann auf Basis einer Wärmebilanzierung dem Betreiber ein optimaler Betrieb vorgeschlagen werden, so dass er hinsichtlich eines ökonomischen und ökologischen Betriebsverhaltens unterstützt wird.In addition, with the measures according to the invention a conveyor for fuels can be controlled, which supplies the filling space accordingly. By determining the fuel charge state, the operator can be proposed on the basis of a heat balance optimal operation, so that it is supported in terms of economic and environmental performance.
