- the known steam generators with the structure mentioned are designed as fully automatic machines in which, after a water pump has been switched on and the flow tube has been filled, and after a predetermined water pressure has been reached, the burner is put into operation with simultaneous supply of combustion air, so that steam generation begins.
- pressure regulators, pressure control valves, pressure limiters, start-up pressure regulators and temperature limiters are used, by means of which the combustion air supply is regulated automatically in such a way that the steam generation, the steam pressure and the temperature are kept constant at the set values.
- preheated water at temperatures of approximately 90-100 ° C. is fed into the flow pipe.
- a fan is arranged at the lower end of the steam generator, which draws in the combustion air from the environment, which then flows through the combustion air flowing up through the second annular gap through the wall of the inner housing the smoke or combustion gases is preheated, which flows in the first annular gap between the inner housing and the jacket formed by the spirally wound flow tube up to the exhaust gas outlet line.
- Another disadvantage of this air duct is that the outer shell of the boiler has a relatively high temperature, which means that additional and expensive insulation measures are required in order to keep the heating of the room or the ambient air from the steam generator low. Such additional heating is particularly disadvantageous and strengthening if, for example, in a laundry or the like. several steam generators are in operation at the same time.
- Atmospheric burners are less powerful than forced draft burners, and atmospheric burners of this type are generally also unsuitable for operation with oil.

- the invention has for its object, on the one hand, to provide measures to improve the efficiency of the burner in order to expose the existing thermal energy without additional energy expenditure to a further increase in the temperature of the combustion air supplied to the burner, wherein it should additionally be ensured that complex insulation measures in the area of outer boiler shell are unnecessary.

This results in an increase in the efficiency of the burner.
Abstract
Description
Die Erfindung betrifft einen Dampferzeuger mit einem spiralförmig zu einem geschlossenen stehenden Mantel gewickelten Durchlaufrohr, welches an seinem unteren Ende einen Wassereinlaß und an seinem oberen Ende einen Dampfauslaß aufweist und einen zylindrischen Hohlraum begrenzt, in den mindestens ein ÖI-oder Gasbrenner gerichtet ist, wobei der den Hohlraum umgebende Mantel mit Bodenabstand und unter Freilassung eines ersten Ringspaltes in einem an seinem oberen Ende an eine Abgasauslaßleitung angeschlossenen Innengehäuse untergebracht ist, das ebenfalls mit Bodenabstand und unter Freilassung eines zweiten Ringspaltes in einem weiteren Gehäuse aufgenommen ist, an dessen unteres Ende ein Gebläse druckseitig angeschlossen ist, um durch den zweiten Ringspalt und den Raum zwischen den Böden des Innengehäuses und des weiteren Gehäuses Verbrennungsluft zu dem Öl- oder Gasbrenner zu fördern.The invention relates to a steam generator with a flow tube wound spirally to a closed standing jacket, which has a water inlet at its lower end and a steam outlet at its upper end and delimits a cylindrical cavity into which at least one oil or gas burner is directed, the the cavity surrounding the casing with ground clearance and leaving a first annular gap is accommodated in an inner housing connected at its upper end to an exhaust gas outlet line, which is also accommodated with a ground clearance and leaving a second annular gap in another housing, at the lower end of which a blower on the pressure side is connected to convey combustion air to the oil or gas burner through the second annular gap and the space between the bottoms of the inner housing and the further housing.
Die bekannten Dampferzeuger mit dem erwähnten Aufbau sind als Vollautomaten ausgebildet, bei denen nach dem Einschalten einer Wasserpumpe und beendeter Füllung des Durchlaufrohres sowie nach Erreichen eines vorgegebenen Wasserdruckes der Brenner bei gleichzeitiger Verbrennungsluftzufuhr in Betrieb gesetzt wird, so daß die Dampferzeugung einsetzt. Zur Regulierung der Dampferzeugung und Dampftemperatur finden Druckregler, Druckhalteventile, Druckbegrenzer, Anfahrdruckregler und Temperaturbegrenzer Anwendung, durch welche die Regelung der Verbrennungsluftzufuhr selbsttätig erfolgt in der Weise, daß die Dampferzeugung, der Dampfdruck und die Temperatur auf eingestellten Werten konstant gehalten werden. Um bei derartigen Dampferzeugern, insbesondere im Bereich des Wassereinlaßbereiches des Durchlaufrohres, den Taupunkt nicht zu unterschreiten und damit eine Rauchgaskondensation und daraus resultierende Korrosionserscheinungen zu vermeiden, wird in das Durchlaufrohr vorgeheiztes Wasser mit Temperaturen von ca. 90 - 100° C eingespeist.The known steam generators with the structure mentioned are designed as fully automatic machines in which, after a water pump has been switched on and the flow tube has been filled, and after a predetermined water pressure has been reached, the burner is put into operation with simultaneous supply of combustion air, so that steam generation begins. To regulate the steam generation and steam temperature, pressure regulators, pressure control valves, pressure limiters, start-up pressure regulators and temperature limiters are used, by means of which the combustion air supply is regulated automatically in such a way that the steam generation, the steam pressure and the temperature are kept constant at the set values. In order to avoid falling below the dew point in such steam generators, especially in the area of the water inlet area of the flow pipe, and thus to avoid smoke gas condensation and the resulting corrosion phenomena, preheated water at temperatures of approximately 90-100 ° C. is fed into the flow pipe.
Bei einem anderen bekannten Dampferzeuger gemäß der FR-A-2 191080 ist am unteren Ende des Dampferzeugers ein Gebläse angeordnet, welches die Verbrennungsluft aus der Umgebung ansaugt, die dann durch die durch den zweiten Ringspalt nach oben strömende Verbrennungsluft durch die Wand des Innengehäuses hindurch von den Rauch- bzw. Verbrennungsgasen vorerhitzt wird, welche in dem ersten Ringspalt zwischen dem Innengehäuse und dem durch das spiralförmig gewickelte Durchlaufrohr gebildeten Mantel nach oben zur Abgasauslaßleitung strömt.In another known steam generator according to FR-A-2 191080, a fan is arranged at the lower end of the steam generator, which draws in the combustion air from the environment, which then flows through the combustion air flowing up through the second annular gap through the wall of the inner housing the smoke or combustion gases is preheated, which flows in the first annular gap between the inner housing and the jacket formed by the spirally wound flow tube up to the exhaust gas outlet line.
Dadurch, daß das Gebläse am unteren Ende des Dampferzeugers, d. h. im unteren Raumbereich liegt, wird kühlere Raumluft angesaugt, was zu einer Verschlechterung der Wärmebilanz führt. Die im unteren Raumbereich angesaugte Verbrennungsluft ist in der Regel relativ stark mit Staub bzw. Schmutzpartikeln belastet, die sich in den Luftführungskanälen des Dampferzeugers ablagern können. Ein wesentliches Nachteil dieses bekannten Dampferzeuger besteht darin, daß die mittels des Geblases angesaugte kalte Verbrennungsluft auf ihrem Weg zum Brenner nur einen einzigen Ringkanal durchströmt, in dem sie von den heißen Verbrennungsgasen vorerwärmt wird. Auf diese Weise wird der Wärmeinhalt der heißen Verbrennungsgase nur relativ geringfügig wiedergewonnen. Ein weiterer Nachteil dieser Luftführung besteht darin, daß der äußere Kesselmantel eine relativ hohe Temperatur hat, wodurch zusätzliche und aufwendige Isoliermaßnahmen erforderlich sind, um die von dem Dampferzeuger ausgehende Erwärmung des Raumes bzw. der Umgebungsluft gering zu halten. Eine derartige zusätzliche Erwärmung ist insbesondere dann nachteilig und stärend, wenn beispielsweise in einer Wäscherei od.dgl. mehrer Dampferzeuger gleichzeitig in Betrieb sind.The fact that the fan at the lower end of the steam generator, d. H. in the lower room area, cooler room air is sucked in, which leads to a deterioration in the heat balance. The combustion air drawn in in the lower area of the room is usually relatively heavily contaminated with dust or dirt particles, which can be deposited in the air duct of the steam generator. A major disadvantage of this known steam generator is that the cold combustion air drawn in by means of the blower only flows through a single annular channel on its way to the burner, in which it is preheated by the hot combustion gases. In this way, the heat content of the hot combustion gases is recovered only relatively slightly. Another disadvantage of this air duct is that the outer shell of the boiler has a relatively high temperature, which means that additional and expensive insulation measures are required in order to keep the heating of the room or the ambient air from the steam generator low. Such additional heating is particularly disadvantageous and strengthening if, for example, in a laundry or the like. several steam generators are in operation at the same time.
Bei einem in der US-A-1 814 605 beschriebenen Dampferzeuger wird die kalte Verbrennungsluft im Bereich des oberen Dampferzeugerendes angesaugt. Die an der Oberseite des Dampferzeugers angesaugte Luft strömt in einem äußeren Ringkanal nach unten und anschließend in einem inneren Ringkanal wieder nach oben, bevor sie zum Brenner gelangt. Auf diese Weise wird der Wärmeinhalt der heißen Verbrennungsgase weitgehend zurückgewonnen, wobei auch eine zusätzliche Isolierung des äußeren Kesselmantels entfallen kann. Die Verbrennungsgasen velassen den bekannten Dampferzeuger durch einen Verbrennungsgasauslaß, an den ein geeignetes Sauggebläse angeschlossen sein kann. Wenn kein derartiges Sauggebläse vorhanden ist, handelt es sich bei dem bei einem solchen Dampferzeuger verwendeten Brenner um einen sogenannten atmosphärischen Brenner, und zwar im Gegensatz zu einem Gebläsebrenner, bei dem ein Gebläse auf der Verbrennungsluftseite Verbrennungsluft ansaugt und dem Brenner unter Druck zuführt. Atmosphärische Brenner haben eine geringere Leistung als Gebläsebrenner, und derartige atmosphärische Brenner sind in der Regel auch nicht fur den Betrieb mit Öl geeignet. Wenn bei diesem bekannten Dampferzeuger auf der Abgasseite ein Sauggebläse angeordnet ist, ist ein solches Gebläse thermisch und chemisch höheren Beanspruchungen ausgesetzt als ein Gebläse auf der Verbrennungsluftseite.In a steam generator described in US-A-1 814 605, the cold combustion air is drawn in in the region of the upper end of the steam generator. The air drawn in at the top of the steam generator flows downwards in an outer ring duct and then upwards again in an inner ring duct before it reaches the burner. In this way, the heat content of the hot combustion gases is largely recovered, and additional insulation of the outer boiler shell can also be omitted. The combustion gases leave the known steam generator through a combustion gas outlet to which a suitable suction fan can be connected. If there is no such suction fan, the burner used in such a steam generator is a so-called atmospheric burner, in contrast to a fan burner in which a fan on the combustion air side sucks in combustion air and supplies it to the burner under pressure. Atmospheric burners are less powerful than forced draft burners, and atmospheric burners of this type are generally also unsuitable for operation with oil. If, in this known steam generator, a suction fan is arranged on the exhaust gas side, such a fan is exposed to higher thermal and chemical stresses than a fan on the combustion air side.
Der Erfindung liegt die Aufgabe zugrunde, einerseits zur Verbesserung des Wirkungsgrades des Brenner Maßnahmen vorzusehen, um die vorhandene Wärmeenergie ohne zusätzlichen - Energieaufwand zu einer weiteren Temperaturerhöhung der dem Brenner zugeführten Verbrennungsluft auszusetzen, wobei zusätzlich gewährleistet sein soll, daß aufwendige Isoliermaßnahmen im Bereich des äußeren Kesselmantels überflüssig sind. Es soll außerdem gewährleistet sein, daß schon die aus der Umgebung angesaugte frische Verbrennungsluft einen relativ hohen Wärmeinhalt hat und möglichst wenig mit Staub-oder Schmutzpartikel belastet sein soll.The invention has for its object, on the one hand, to provide measures to improve the efficiency of the burner in order to expose the existing thermal energy without additional energy expenditure to a further increase in the temperature of the combustion air supplied to the burner, wherein it should additionally be ensured that complex insulation measures in the area of outer boiler shell are unnecessary. It should also be ensured that the fresh combustion air sucked in from the surroundings already has a relatively high heat content and should be contaminated as little as possible with dust or dirt particles.
Zur Lösung dieser Aufgabe ist der erfindungsgemäße Dampferzeuger dadurch gekennzeichnet, daß das weitere Gehäuse mit Boden- und Deckenabstand und unter Freilassung eines dritten Ringspaltes in einem Außengehäuse untergebracht ist, das an seiner Oberseite mit einer Ansaugöffnung für Verbrennungsluft versehen ist und im Bereich seines unteren Endes an die Saugseite des Gebläses angeschlossen ist.To achieve this object, the steam generator according to the invention is characterized in that the further housing with floor and ceiling spacing and with the release of a third annular gap is accommodated in an outer housing which is provided on its upper side with a suction opening for combustion air and in the region of its lower end the suction side of the fan is connected.
Während bei dem in der FR-A-2 191 080 beschriebenen Dampferzeuger die Verbrennungsluft aus dem unteren Raumbereich direkt aus der Umgebung angesaugt wird, wird bei dem erfindungsgemäßen Dampferzeuger die Verbrennungsluft aus dem oberen Raumbereich durch den von dem Außengehäuse umgebenen dritten Ringspalt im Gegenstrom zu der durch den zweiten Ringspalt nach oben strömenden Verbrennungsluft angesaugt, wodurch die der Saugseite des Gebläses zugefuhrte Verbrennungsluft bereits eine Vorerwärmung erfährt. Die bisher an die Umgebung abgegebene Strahlungswärme wird somit zur Vorerwärmung der von dem Gebläse angesaugten Verbrennungsluft ausgenutzt. Die im oberen Raumbereich angesaugte Verbrennungsluft hat auch einen höheren Wärmeinhalt und ist weniger mit Staub- bzw. Schmutzpartikel belastet als im unteren Raumbereich angesaugte Luft. Infolge des dem Gebläse vorgeschalteten Zwischenkanals werden zusätzlich die sonst üblichen Ansauggeräusche von Luftgebläsen stark gedämpft.While in the steam generator described in FR-A-2 191 080 the combustion air is sucked in directly from the surroundings from the lower room area, in the steam generator according to the invention the combustion air from the upper room area is countercurrent to the third ring gap surrounded by the outer housing Combustion air flowing upwards through the second annular gap, whereby the combustion air supplied to the suction side of the fan is already preheated. The radiant heat previously released to the environment is thus used to preheat the combustion air sucked in by the fan. The combustion air drawn in in the upper room area also has a higher heat content and is less contaminated with dust or dirt particles than air drawn in in the lower room area. As a result of the intermediate duct upstream of the blower, the usual suction noises from air blowers are also strongly damped.
Verglichen mit dem in der US-A-1 814 605 beschriebenen Dampferzeuger liegt der Vorteil des erfindungsgemäßen Dampferzeugers im wesentlichen darin, daß ein vorgeschalteter Gebläsebrenner vorhanden ist, mit dem die Verbrennungsluft dem Brenner unter Druck zugeführt wird. Ein dem Brenner vorgeschaltetes Gebläse wird auch thermisch und chemisch weniger belastet als ein im Bereich der Abgasseite angeordnetes Sauggebläse.Compared to the steam generator described in US-A-1 814 605, the advantage of the steam generator according to the invention is essentially that there is an upstream fan burner with which the combustion air is supplied to the burner under pressure. A fan upstream of the burner is also subjected to less thermal and chemical stress than a suction fan arranged in the area of the exhaust gas side.
Die Erfindung wird im folgenden anhand der Zeichnungen näher beschrieben. Die Figuren 1 und 2 zeigen in mehr oder weniger schematischer Darstellung eine Ausführungsform des erfindungs gemäßen Dampferzeugers.The invention is described below with reference to the drawings. Figures 1 and 2 show a more or less schematic representation of an embodiment of the steam generator according to the Invention.
Der in der Zeichnung schematisch dargestellte Dampferzeuger besteht im wesentlichen aus dem in einer oder mehreren Lagen spiralförmig gewundenen Durchlaufrohr 1, welches zu einem geschlossenen Mantel 7 gewickelt ist. Das untere Ende des Durchlaufrohres 1 ist an einen Wassereinlaß 8 und das obere Ende an einen Dampfauslaß 9 angeschlossen. In dem von dem Mantel 7 begrenzten Hohlraum ist ein Öl- oder Gasbrenner 10 gerichtet, dessen Heiz- und Verbrennungsgase in dem Hohlraum und damit an der Innenfläche des von dem Durchlaufrohr gebildeten Mantels nach unten strömen. Der den Hohlraum umgebende Mantel 7 ist mit Bodenabstand und unter Freilassung eines ersten Ringspaltes 11 von einem Innengehäuse 2 umgeben, das an seinem oberen Ende an eine Abgasauslaßleitung 12 für die in dem ersten Ringspalt 11 in Richtung des Pfeiles a nach oben strömenden Abgase angeschlossen ist.The steam generator shown schematically in the drawing essentially consists of the
Das Innengehäuse 2 ist mit Boden- und Deckenabstand und unter Freilassung eines zweiten Ringspaltes 13 von einem weiteren Gehäuse 3 umgeben. Dieser zweite Ringspalt ist im Bereich seines unteren Endes an die Druckseite eines Gebläses 6 und an seinem oberen Ende an den Brenner 10 angeschlossen, um diesem in Richtung der Pfeile b Verbrennungsluft zuzuführen. Diese in Richtung der Pfeile b strömende Verbrennungsluft wird von den durch den ersten Ringspalt 11 in Gleichstrom nach oben strömende Abgasen erhitzt.The
Das weitere Gehäuse 3 ist mit Boden- und Deckenabstand und unter Freilassung eines dritten Ringspaltes 14 in einem Außengehäuse 4 untergebracht, das an seiner Oberseite mit einer vorzugsweise durch einen Filter oder ein Gitter 15 abgedeckten Ansaugöffnung 5 für Verbrennungsluft versehen ist und im Bereich seines unteren Endes an die Saugseite des Gebläses 6 angeschlossen ist. Die durch den dritten Ringspalt 14 in Richtung der Pfeile c strömende und aus der Umgebung angesaugte Verbrennungsluft wird somit in Gegenstrom zu der durch den zweiten Ringspalt 13 aufsteigenden erhitzten Verbrennungsluft vorerwärmt, wodurch insgesamt eine über das bisherige Maß hinausgehende Erwärmung der dem Brennung zugeführten Verbrennungsluft stattfindet. Daraus resultiert eine Erhöhung des Wirkungsgrades des Brenners.The
