Pour améliorer encore plus son efficacité, on a prévu à l'entrée du registre (11) une soupape d'étranglement actionnée en fonction de la température du fluide, ce qui permet, grâce à l'étranglement de l'écoulement, de maintenir la différence de température entre l'entrée et la sortie du fluide à une valeur relativement élevée, même lorsque la température du fluide augmente.Device for a heating installation with a combustion chamber (3) for a burner, combustion chamber (3) which is surrounded by a double jacket through which the fluid to be heated passes. To improve its efficiency, a damper (11) is placed in the combustion chamber and exposed to the flame before the double envelope. To further improve its efficiency, a throttle valve actuated as a function of the temperature of the fluid is provided at the inlet of the damper (11), which, thanks to the throttling of the flow, makes it possible to maintain the temperature difference between the inlet and outlet of the fluid to a relatively high value, even when the temperature of the fluid increases.

Description

Einrichtung an einer Heizanlage Installation on a heating system
Die Erfindung bezieht sich auf eine Einrichtung an einer Heiz¬ anlage mit einem Heizkessel mit einem Brennraum, in den ein Brenner hineinragt und der von einem Doppelmantel umgeben ist, der mit einem Zu- und einem Ablauf versehen und von dem zu er¬ wärmenden Fluid durchströmt ist.The invention relates to a device on a heating system with a boiler with a combustion chamber into which a burner protrudes and which is surrounded by a double jacket which is provided with an inlet and an outlet and through which the fluid to be heated flows is.
Um den Wirkungsgrad einer solchen Einrichtung zu verbessern wurde schon vorgeschlagen, den Doppelmantel im Bereich des Brennraumes mit Rauchführungsröhren zu durchsetzen, die über einen Rauchsammeiraum in einen Rauchabzug münden. Damit läßt sich die eingesetzte Primärenergie besser ausnützen.In order to improve the efficiency of such a device, it has already been proposed to enforce the double jacket in the area of the combustion chamber with smoke guide tubes which open into a smoke vent via a smoke collection room. This makes better use of the primary energy used.
Weiters wurde zur weiteren Verbesserung des Wirkungsgrades auch schon vorgeschlagen, die aus dem Kessel in den Rauchabzug ab¬ strömenden und noch eine erhebliche Temperatur"aufweisenden Gase über einen dem Doppelmantel des Kessels, der von dem zu erwärmenden Wasser gefüllt ist, vorgeschalteten Wärmetauscher zu leiten. Dabei ergibt sich jedoch ein erheblicher Nachteil. So kommt es durch die starke Abkühlung der Abgase an den vom re- lativ kalten Wasser durchströmten Wärmetauscher leicht zu Ver- sottungserscheinungen, durch die der Wärmetauscher rasch ver¬ schmutzt und den Durchzug der Abgase behindert, wodurch die Verbrennung im Brennraum leidet und daher der Wirkungsgrad der Anlage sinkt.Furthermore, the efficiency has been to further improve also been proposed, the flowing ab¬ from the boiler into the flue, and to conduct still a significant temperature "comprising gases over a the double jacket of the boiler, which is filled by the water to be heated upstream heat exchanger. However, this results in a considerable disadvantage: the strong cooling of the exhaust gases at the heat exchanger through which the relatively cold water flows leads to signs of sooting, which quickly contaminate the heat exchanger and hinder the passage of the exhaust gases, thereby preventing the exhaust gases from passing through Combustion in the combustion chamber suffers and therefore the efficiency of the system drops.
Ziel der Erfindung ist es, diese Nachteile zu vermeiden und eine Einrichtung der eingangs erwähnten Art vorzuschlagen, die sich durch einen besonders hohen Wirkungsgrad auszeichnet und bei der eine Versottung weitgehend vermieden ist.The aim of the invention is to avoid these disadvantages and to propose a device of the type mentioned at the outset which is distinguished by a particularly high degree of efficiency and in which sooting is largely avoided.
Sft Erfindungsgemäß wird dies dadurch erreicht, daß in dem Brenn¬ raum ein Register angeordnet ist, das dem Doppelmantel vorge¬ schaltet ist.Sft According to the invention, this is achieved in that a register is arranged in the combustion chamber, which is connected upstream of the double jacket.
Dadurch wird das dem Doppelmantel zugeleitete Fluid vor dem Ein¬ strömen in diesen durch die direkte Einwirkung der Flamme des Brenners vorgewärmt, wobei aufgrund der Hitze der Flamme keine Vefsottung im Bereich des Registers zu befürchten ist und auch keine Verminderung des Luftdurchsatzes durch den Brennraum ein¬ tritt. Durch das Vorheizen des Wassers, bevor es in den Doppel¬ mantel einströmt, wird die Laufzeit des Brenners wesentlich verkürzt, wodurch sich Energieeinsparungen ergeben.As a result, the fluid supplied to the double jacket is preheated before it flows into it by the direct action of the flame of the burner, whereby there is no fear of fouling in the area of the register due to the heat of the flame and no reduction in the air throughput through the combustion chamber occurs. By preheating the water before it flows into the double jacket, the runtime of the burner is considerably shortened, which results in energy savings.
Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß die die beiden Sammler des Registers verbindenden Leitungen durch Vierkantrohre gebildet sind, wodurch sich aufgrund des im Ver¬ hältnis der Querschnittsfläche relativ großen ümfanges der ver¬ bindenden Leitungen ein sehr guter Wärmeübergang ergibt.According to a further feature of the invention it is provided that the lines connecting the two collectors of the register are formed by square tubes, which results in a very good heat transfer due to the relatively large circumference of the connecting lines in relation to the cross-sectional area.
Weiters kann vorgesehen sein, daß Zu- und Ablaufstutzen des Registers an dem selben Sammler angeordnet sind, wobei ein Zulauf- und zwei Ablaufstutzen vorgesehen sind, zwischen denen die Sammler unterteilende Trennwände angeordnet sind, wodurch sich sehr günstige Strömungsverhältnisse ergeben.It can further be provided that the inlet and outlet connections of the register are arranged on the same collector, one inlet connection and two outlet connections being provided, between which the collectors are arranged, which results in very favorable flow conditions.
Um den Wirkungsgrad der Einrichtung noch weiter zu verbessern, kann vorgesehen sein, daß im Zulauf des Registers ein den Durch¬ fluß steuerndes Drosselventil, z.B. eine Motorklappe angeordnet ist, das in Abhängigkeit von einem die Temperatur des Fluids erfassenden Fühler gesteuert ist.In order to further improve the efficiency of the device, it can be provided that a throttle valve controlling the flow, e.g. a motor flap is arranged which is controlled as a function of a sensor which detects the temperature of the fluid.
Dadurch wird erreicht, daß die Temperaturdifferenz zwischen dem Kesselzulauf und dem Kesselablauf durch Verminderung des Durch¬ laufes durch den Kessel relativ groß gehalten werden kann, auch wenn die Temperatur des zu erwärmenden Fluids steigt. Damit wird der Nachteil der sich bei üblichen Heizanlagen, bei denen die Temperatur der Heizkörper in der Regel durch ein den Rücklauf von den Heizkörpern oder einer Gruppe von Heizkörpern mit deren Vorlauf mischenden Mischventile geregelt wird und bei denen stets der volle Durchfluß durch den Kessel aufrecht erhalten wird, ergibt vermieden, der durch die bei steigender Temperatur des Fluids verminderten Temperaturdifferenz zwischen dem Zu- und dem Ablauf des Kessels bedingt ist. - ^ It is thereby achieved that the temperature difference between the boiler inlet and the boiler outlet can be kept relatively large by reducing the passage through the boiler, even if the temperature of the fluid to be heated rises. This is the disadvantage of conventional heating systems, in which the temperature of the radiator is usually caused by a return of the radiators or a group of radiators with their flow mixing valves is regulated and in which the full flow through the boiler is always maintained, results in avoided by the reduced temperature difference between the inlet and outlet of the boiler with increasing temperature of the fluid is conditional. - ^
Außerdem wird durch diese Maßnahmen der Vorrang der Regelung des Kessels gegenüber jener des -Heizkörpers sichergestellt, wodurch sich für den Kessel günstigere Betriebsbedingungen ergeben.In addition, these measures ensure the priority of the boiler control over that of the radiator, which results in more favorable operating conditions for the boiler.
Besonder günstige Verhältnisse ergeben sich wenn der die Tempera¬ tur des Fluids erfassende Fühler in einer den Ausgang des Regist¬ ers mit dem Kessel verbindenden Leitung, in der vorzugsweise ein Pufferspeicher für das Fluid sowie gegebenenfalls ein die Brennerleistung steuernder Temperaturfühler vorgesehen sind, angeordnet ist. Durch die Anordnung eines Pufferspeichers, wird eine Verminderung der Zeitabschnitte erreicht in denen der Brenner in Betrieb ist. Durch. Anordnung eines die Brenner¬ leistung steuernden*..Temperaturfühlers gelingt es, bei Erreichen einer entsprechenden Temperatur des Fluids eine entsprechende An¬ passung der Brennerleistung an den tatsächlichen Bedarf zu er¬ möglichen, wodurch sich ebenfalls Energieeinsparungen ergeben.Particularly favorable conditions result when the sensor which detects the temperature of the fluid is arranged in a line connecting the outlet of the register to the boiler, in which a buffer store for the fluid and optionally a temperature sensor controlling the burner output are preferably provided. The arrangement of a buffer memory reduces the time periods in which the burner is in operation. By. An arrangement of a *. Temperature sensor controlling the burner output succeeds in making a corresponding adaptation of the burner output to the actual demand possible when a corresponding temperature of the fluid is reached, which also results in energy savings.
Besonders günstige Betriebsbedingungen ergeben sich, wenn der Fühler mit einem Regler verbunden ist, der die Stellung des Drosselventiles steuert. Dadurch kann der Durchfluß durch den Kessel entsprechend der jeweiligen Temperatur des Fluids ge¬ regelt werden.Particularly favorable operating conditions result when the sensor is connected to a controller that controls the position of the throttle valve. The flow through the boiler can thereby be regulated in accordance with the respective temperature of the fluid.
Grundsätzlich ist es aber auch möglich, mit einem geringeren konstruktiven Aufwand das Auslangen zu finden. So kann auch eine einfache Zweipunktregelung für das Drosselventil vorgesehen und dieses mit einem entsprechend langsam laufenden Antrieb ver¬ sehen sein. In diesem Fall genügt ein Thermostat als Fühler, der bei Erreichen einer entsprechenden Temperatur den Antrieb des Drosselventiles startet, sodaß dieses in Richtung auf seine maximal gedrosselte Stellung zu läuft und dadurch den Durch¬ fluß langsam vermindert. Sinkt die Temperatur des Fluides z.B. aufgrund eines plötzlich erhöhten Wärmebedarfs ab, so steuert der Thermostat den Antrieb des Drosslventils entsprechend um und dieses beginnt langsam aus der gedrosselten Stellung gegen die voll geöffnete Stellung zu laufen. Bei dieser einfachen Steuer¬ ung sind allerdings Schwingungen der Regelung nicht zu vermeiden.In principle, however, it is also possible to find what is needed with less design effort. A simple two-point control can also be provided for the throttle valve and this can be provided with a correspondingly slow-running drive. In this case, a thermostat is sufficient as a sensor that starts driving the throttle valve when a corresponding temperature is reached, so that it moves in the direction of its maximum throttled position runs and thereby slowly reduces the flow. If the temperature of the fluid drops, for example due to a sudden increase in heat demand, the thermostat reverses the drive of the throttle valve and this begins to run slowly from the throttled position to the fully open position. With this simple control, however, vibrations of the control cannot be avoided.
Die Erfindung wird nun anhand der Zeichnung näher erläutert. Da¬ bei zeigt:The invention will now be explained in more detail with reference to the drawing. Here shows:
Figur 1 schematisch eine erfindungsgemäße Einrichtung und Figur 2 schematisch ein Register.Figure 1 schematically shows a device according to the invention and Figure 2 schematically shows a register.
Der Heizkessel 1 weist eine Brennraumtür 2 auf, in -deren Öffnung ein nicht dargestellter Brenner einsetzbar ist. Der Brennraum 3 des Kessels ist durch einen Doppelmantel 4 begrenzt, der über einen Einlaß- und einen Auslaßstutzen 5,6 an einen Wasserkreis¬ lauf 7, z.B. für eine Heizung, anschließbar ist. Dabei ragt der Auslaßstutzen 6 durch den eigentlichen Doppelmantel 4 hindurch in einen mit diesem kommunizierenden Zusatzbehälter 8 hinein, der von Rauchführungsröhren 9 durchsetzt ist. Diese Rauchführ¬ ungsrohre 9 leiten die Abgase vom Brennraum 3 in einen Rauch¬ sammeiraum 10, von dem sie in einen nicht dargestellten Abzug abströmen.The boiler 1 has a combustion chamber door 2, in the opening of which a burner (not shown) can be used. The combustion chamber 3 of the boiler is delimited by a double jacket 4, which is connected via an inlet and an outlet nozzle 5, 6 to a water circuit 7, e.g. for heating, can be connected. The outlet nozzle 6 protrudes through the actual double jacket 4 into an additional container 8 which communicates with the latter and is penetrated by smoke guide tubes 9. These smoke guide pipes 9 guide the exhaust gases from the combustion chamber 3 into a smoke collection space 10, from which they flow into a fume cupboard, not shown.
In dem Brennraum ist weiters ein Register 11 angeordnet, das direkt der Einwirkung der Flamme des Brenners ausgesetzt ist. Dieses Register ist dem Doppelmantel 4 vorgeschaltet, sodaß der Rücklauf des Wasserkreislaufes an den Einlauf 12 des Registers 11 angeschlossen ist. Der Auslaufstutzen 13 des Registers 11 ist mit einem Pufferspeicher 14 verbünden, dessen Auslaß mit dem Einlaßstutzen 5 des Doppelmantels 4 verbunden ist.A register 11 is also arranged in the combustion chamber and is directly exposed to the action of the flame of the burner. This register is connected upstream of the double jacket 4, so that the return of the water circuit is connected to the inlet 12 of the register 11. The outlet connection 13 of the register 11 is connected to a buffer store 14, the outlet of which is connected to the inlet connection 5 of the double jacket 4.
Dem Einlaßstutzen 12 des Registers 11 ist ein Drosselventil 15 vorgeschaltet, das mittels eines Motors verstellbar ist und den Zufluß von dem Heizkörper 16 her regelt, der durch die Pumpe 17 bewirkt wird.A throttle valve 15, which is adjustable by means of a motor and regulates the inflow from the heating element 16, which is generated by the pump 17, is connected upstream of the inlet connection 12 of the register 11 is effected.
In der Leitung 18 vom Auslaßstutzen 13 des Registers 11 zum Pufferspeicher 14 ist ein Temperaturfühler 19 eingebaut. Dieser ist mit einer nicht dargestellten Regelung verbunden, die ihrerseits mit dem Drosselventil 15 bzw. dessen Motor verbunden ist.A temperature sensor 19 is installed in the line 18 from the outlet connection 13 of the register 11 to the buffer store 14. This is connected to a control system, not shown, which in turn is connected to the throttle valve 15 or its motor.
Die Regelung des Drosselventils 15 kann entweder als Zweipunkt¬ regelung ausgebildet sein, wobei der Temperaturfühler bei Er¬ reichen einer bestimmten Temperatur ein Signal abgibt, das dazu führt, daß das Drosselventil gegen seine maximal offene Stellung zu läuft. Dabei ist eine entsprechend langsame Bewegung des Ventilkörpers vorgesehen. Bei Unterschreiten einer bestimmten Temperatur des Wassers gibt der Temperaturfühler 19 ein Signal ab, das das Zurücklaufen des Drosselventils 15 in seine maximal geschlossene Stellung bewirkt.The control of the throttle valve 15 can either be designed as a two-point control, the temperature sensor emitting a signal when a certain temperature is reached, which leads to the throttle valve running towards its maximum open position. A corresponding slow movement of the valve body is provided. If the temperature of the water falls below a certain level, the temperature sensor 19 emits a signal which causes the throttle valve 15 to return to its maximum closed position.
Für eine exaktere Regelung kann jedoch auch ein PI-Regler vorge¬ sehen sein, wobei jedoch der Fühler 19 ein entsprechendes analoges Signal abgeben muß. In diesem Falle wird der Durchfluß durch den Kessel bzw. das Register 11 und den Doppelmantel in Abhängigkeit von der momentanen Temperatur des Wassers geregelt.However, a PI controller can also be provided for more precise control, although the sensor 19 must emit a corresponding analog signal. In this case, the flow through the boiler or the register 11 and the double jacket is regulated depending on the current temperature of the water.
Um eine weitere Engergieeinsparung zu ermöglichen, i-st in der Leitung 18 noch ein Thermostat 20 eingebaut, der bei Erreichen einer bestimmten Temperatur den Brenner von Vollast auf Teillast umschaltet.In order to enable further energy savings, a thermostat 20 is also installed in line 18, which switches the burner from full load to part load when a certain temperature is reached.
Weiters ist in der Leitung 18 noch ein Sicherheitsthermostat 21 eingebaut, der bei Erreichen einer gefährlich hohen Temperatur den Brenner absperrt.Furthermore, a safety thermostat 21 is installed in line 18, which shuts off the burner when a dangerously high temperature is reached.
Wie aus Figur 2 ersichtlich, weist das Register 11 einen vorderen und einen hinteren Sammler 14,15 auf, die über Leitungen 16 aus Vierkant-Rohren verbunden sind.As can be seen from FIG. 2, the register 11 has a front and a rear header 14, 15, which are connected via lines 16 made of square tubes.
ERSATZBLATT Der hintere Sammler 15 wiest einen Einlauf 12 und zwei Ausla߬ stutzen 13 auf und ist durch zwei Trennwände 17, die zu beiden Seiten des Einiaufs angeordnet sind, unterteilt. Das einströmende Wasser fließt vom hinteren Sammler 15 über einen Teil der Leit¬ ungen 16 zum vorderen Sammler, wo es hochsteigt und über einen anderen Teil der Leitungen in den hinteren Sammler 15 zurück¬ strömt und anschließend über die beiden Auslaßstutzen 13 zum Einlaßstutzen des Doppelmantels 4 strömt.REPLACEMENT LEAF The rear header 15 has an inlet 12 and two outlet ports 13 and is divided by two partition walls 17 which are arranged on both sides of the inlet. The inflowing water flows from the rear header 15 via part of the lines 16 to the front header, where it rises and flows back into the rear header 15 via another part of the lines and then via the two outlet ports 13 to the inlet port of the double jacket 4 flows.
Da das Register 11 der Einwirkung der Flamme des Brenners ' aus¬ gesetzt ist, wird das durch das Register 11 strömende Wasser er¬ wärmt, bevor es in den Doppelmantel einströmt. Since the register 11 'is set aus¬ the action of the flame of the burner, the gas flowing through the register 11 er¬ water is heated before it flows into the double jacket.
