Description

  

   <Desc/Clms Page number 1> 
 Heizkessel für Warmwasserheizungen, insbesondere für Gewächshäuser Die Erfindung betrifft einen Heizungskessel für Warmwasserheizungen, und zwar insbesondere für Gewächshäuser. 



  Bei derartigen Heizungskesseln ist es bekannt, den eigentlichen Federungsraum und die darüber angeordneten    Abzugskanäle   für die    Verbrennungsgase   in einem    geschlossenen      Kessel      anzuordnen,   in dem sich das aufzuwärmende Wasser befindet. Die    Heiz-      flamme,   die üblicherweise von einem Ölbrenner erzeugt wird, wird dabei vorzugsweise stirnseitig und axial in den langgestreckten Federungsraum eingeleitet. 



  Die bekannten Heizungskessel dieser Art sind konstruktiv zu aufwendig und wenig wohlfeil. Auch haben diese Konstruktionen keine sehr günstige Wärmeausnutzung. 



  Die Erfindung bezweckt, diese Nachteile abzustellen. Sie schlägt vor, dass die Wandung des eigentlichen Federungsraumes wellenförmig ausgebildet ist, wobei die Wellengen in axialer Richtung verlaufen und eine solche Krümmung aufweisen, dass sie, von der    Achse   des    Federungsraumes   aus    gesehen,   auf ihrer gesamten Fläche direkt bestrahlt werden. Die Erfindung sieht ferner vor, dass die Abzugskanäle je aus zwei aneinandengelegten Wellenblechen oder zickzackförmigen Blechen gebildet sind, die an ihren Berührungslinien oder nur an ihrer Ober- und Unterkante miteinander verschweisst sind. Dadurch ergeben sich mehrere neben- bzw. übereinanderliegende    Ab-      zusgkanäle.   



  Im einzelnen ist die Erfindung in der Zeichnung beispielsweise näher veranschaulicht. Es zeigen: Fig. 1 einen erfindungsgemässen Kesses in teilweise im Schnitt gehaltener Seitenansicht und Fig. 2 den Kessel im Querschnitt. In einem in sich geschlossenen Kesselrauen 1 befindet sich ein langgestreckter Feuerungsraum 2. An der einen Stirnfläche 3 dieses Feuerungsraumes 2 ist ein üblicher Ölbrenner 4 angeordnet, der den Raum 2 etwa in axialer Richtung gemäss den strichpunktierten gezeichneten Linien a befeuert. An der Stirnfläche 2a des Raumes 2 wird der Feuerungsstrahl bzw. wenden die Verbrennungsgase umgeleitet und gelangt bzw. gelangen durch eine Öffnung 5 zu den Abzugskanälen 6.

   Durch die Wärmeabgabe der    Verbrennungsgase   an die Mantelfläche des Federungsraumes 2 bzw. an die Kanäle 6 wird das in dem Kessel 1 befindliche und den Feuerungsraum 2 und die    Abzugskanäle   6    umspülende   Wasser aufgeheizt. 



  Dieses Wasser tritt in bekannter Weise durch einen Wasserzulauf 7 im unteren Teil des Kessels ein und gelangt über den Vorlaufstutzen 8 zu den eigentlichen Versorgungsstellen. Die Verbrennungsgase ziehen nach    dem   Durchströmen der Kanäle 6 über einen Kamin 9 nach .aussen ab. 



  Um eine .gute    Wärmeausnutzung   in dem    Fede-      rungsraum   2 zu erzielen,    weist   dieser    eine   wellenförmige Wandung 2b auf, wobei diese Wellengen in axialer    Richtung   .des    Federungsraumes   2 verlaufen. Dadurch wird eine grössere Bestrahlungsfläche des    Federungsraumes   2 erzielt, was naturgemäss zu einer besseren    Wärmeausnutzung   führt.

   Im übrigen sind die    Wellengen   so .ausgeführt,    @dass   :sie, von der    .Achse   2c des Federungsraumes 2, direkt zu bestrahlen sind; d. h. dass jeder von der Achse 2c gezogene Radius    unmittelbar   jeden    Punkt   der    Wellengen   erreichen kann. 



  Der Federungsraum 2 ist in :dem Kessel 1 auf    Böcken   10    gelagert   und nach oben    ,hin      mittels      Ver-      stärkurngsrippen   11 an    den   Kanälen 6 befestigt. 

 <Desc/Clms Page number 2> 

 Die Abzugskanäle 6 sind, wie insbesondere aus Fig. 2 ersichtlich, aus jeweils zwei aneinanderliegenden Wellblechen 6a und 6b gebildet, wobei diese an ihren Berührungslinien 6c miteinander verschweisst sind. Dadurch wenden in wahlfeiler und einfacher Art die Kanäle 6 gebildet. Wie aus Fig. 2 ersichtlich ist, brauchen die Wellbleche nicht unbedingt runde Wellungen aufzuweisen, sondern können auch eckig ausgeführt sein.

   Die Verschweissung muss im übrigen nicht an sämtlichen Berührungslinien 6c erfolgen, sondern kann sich auf die Ober- und Unterkante beschränken. Das hat den Vorteil einer    besseren   Ausdehnungsmöglichkeit der Bleche bei der unterschiedlichen Wärmebeanspruchung. 



  In den einzelnen Kanälen sind noch, wie Fig. 1 erkennen lässt, Blecheinsätze 6d angeordnet, die ein direktes axiales Durchströmen der Verbrennungsgase durch diese Kanäle verhindern und dafür sorgen, dass diese zickzackartig hindurchgeführt werden. 



  Der Kessel 1 kann auf dem Boden aufgestellt werden, wozu entsprechend an ihm angebrachte Schienen 12 dienen. Am Kessel ist ferner eine Rücklauf- und Vorlaufsicherheitsleitung 8a und 7a vorgesehen. Vor dem Abzugskamin 9 ist ein    Rauchgas-      sammelkasten   angeordnet, der mit einer Sicherungsund Reinigungsklappe 14 versehen ist. Schliesslich weist der Kessel noch eine wassergekühlte Tür 16 mit wasserdurchlaufenen Scharnieren 17 auf. Durch ein Schauglas 15 können die Vorgänge im Kesselinnern beobachtet werden.

 Boiler for warm water heating, in particular for greenhouses The invention relates to a heating boiler for warm water heating, in particular for greenhouses.



  In such heating boilers it is known to arrange the actual suspension space and the ducts for the combustion gases arranged above it in a closed boiler in which the water to be heated is located. The heating flame, which is usually generated by an oil burner, is preferably introduced into the elongated suspension space at the end and axially.



  The known heating boilers of this type are too expensive to construct and not very cheap. These constructions also do not have very favorable heat utilization.



  The invention aims to overcome these disadvantages. It suggests that the wall of the actual suspension space is designed in a wave-like manner, the corrugations running in the axial direction and having such a curvature that, viewed from the axis of the suspension space, they are directly irradiated over their entire surface. The invention further provides that the drainage channels are each formed from two corrugated sheets or zigzag sheets placed next to one another, which are welded to one another at their contact lines or only at their upper and lower edges. This results in several exhaust ducts lying next to or one above the other.



  The invention is illustrated in detail in the drawing, for example. 1 shows a kettle according to the invention in a partially sectioned side view, and FIG. 2 shows the kettle in cross section. In a closed boiler shell 1 there is an elongated furnace 2. At one end face 3 of this furnace 2, a conventional oil burner 4 is arranged, which fires the chamber 2 approximately in the axial direction according to the dash-dotted lines a. At the end face 2a of the room 2, the firing jet or the combustion gases are diverted and arrive or arrive through an opening 5 to the exhaust ducts 6.

   As a result of the heat given off by the combustion gases to the outer surface of the suspension chamber 2 or to the channels 6, the water located in the boiler 1 and around the furnace 2 and the exhaust channels 6 is heated.



  This water enters in a known manner through a water inlet 7 in the lower part of the boiler and reaches the actual supply points via the flow connection 8. After flowing through the ducts 6, the combustion gases draw out via a chimney 9.



  In order to achieve good heat utilization in the suspension space 2, the latter has an undulating wall 2b, these undulations running in the axial direction of the suspension space 2. As a result, a larger irradiation area of the suspension space 2 is achieved, which naturally leads to a better utilization of heat.

   Otherwise, the shafts are designed so that: they are to be irradiated directly from the axis 2c of the suspension space 2; d. H. that every radius drawn from the axis 2c can directly reach every point on the shafts.



  The suspension space 2 is mounted in: the boiler 1 on brackets 10 and is fastened to the channels 6 at the top by means of reinforcing ribs 11.

 <Desc / Clms Page number 2>

 As can be seen in particular from FIG. 2, the drainage channels 6 are each formed from two corrugated sheets 6a and 6b lying against one another, these being welded to one another at their contact lines 6c. As a result, the channels 6 are formed in an optional and simple manner. As can be seen from FIG. 2, the corrugated metal sheets do not necessarily have to have round corrugations, but can also be made angular.

   The welding does not have to take place on all of the contact lines 6c, but can be limited to the upper and lower edges. This has the advantage that the sheets can expand better with the different thermal loads.



  In the individual channels, as can be seen in FIG. 1, sheet metal inserts 6d are also arranged, which prevent the combustion gases from flowing axially directly through these channels and ensure that they are passed through in a zigzag fashion.



  The boiler 1 can be set up on the floor, for which purpose rails 12 attached to it are used. A return and flow safety line 8a and 7a is also provided on the boiler. A flue gas collecting box, which is provided with a safety and cleaning flap 14, is arranged in front of the exhaust chimney 9. Finally, the boiler also has a water-cooled door 16 with hinges 17 through which water flows. The processes inside the boiler can be observed through a sight glass 15.
