Definitions
- the invention relates to a gas boiler consisting of a water-bearing housing with upper front and lower Return connection and with arranged in the upper part of the housing combustion chamber equipped with surface burner, of whose Circumferential wall made substantially parallel to each other and vertically arranged heating gas pockets to one at the bottom Exhaust gas collection chamber arranged with exhaust gas connection lead, in the upper area of the heating gas pockets and at a distance from the peripheral wall of the combustion chamber between the heating gas pockets the one between them outflowing heat transfer medium bundling and against one Partial area of the peripheral wall directing flow guides are arranged.
- a boiler of this type is known, for example, according to EP-A-0 271 434, in which, however, the pocket packet is not attached to the peripheral wall of the combustion chamber but to the bottom thereof, and in which several horizontal partition walls are used over the entire height of the pocket packet, in order to structure the upflow space in the pockets between the pockets for the return and to ensure a targeted flow against the combustion chamber floor on the last floor.
- a gas boiler of the relevant type is also known, for example according to DE-A-43 01 804, whose pot-like combustion chambers, which, however, are oriented horizontally with their axes, are equipped with hemispherical gas surface burners, lead to an extremely compact design of the entire combustion chamber area and, in this respect, as well of the entire gas boiler, which, however, is associated with a high thermal load on the combustion chamber walls, in particular in the area of the connections of the downward heating gas draft pockets, the connection opening cross sections of which reduce the area of the combustion chamber peripheral wall which can be cooled in this area accordingly.
- the invention is therefore based on the object, gas boiler of the generic type with simple means to improve in that the high density in Connection area of the heating gas draw pockets to the peripheral wall of the combustion chamber transferred heat on the water side is dissipated and boiling noises are prevented, connected with the stipulation, from the outset for one as even as possible supply of the return in all To provide pocket gaps that when arranging a simple return connection in conventionally am water-bearing housing of the boiler is not given is.
- FIG. 1 to 3 there is the gas boiler from a water-bearing housing 1 with an upper Flow connection 2 and lower return connection 3 and with arranged in the upper housing part 1 ', with surface burner 4 equipped combustion chamber 5, from its peripheral wall 6 essentially parallel and vertical to each other arranged Bankgaszugtaschen 7 to one at the bottom of the housing 1 arranged exhaust gas collection chamber 8 with exhaust gas connection 9 lead.
- Flow guides 10 arranged.
- FIG. 1 shows an embodiment in which the funnel-shaped flow guides 10 as Parts or connecting parts from the two open sides S of the pocket packet P veneered walls 14 are, with a part of the walls 14 as a flow trap 14 'is arranged above the return port 3.
- the thereby bundled, specifically to the outflow openings A guided, accelerated there and against the middle Area of the combustion chamber peripheral wall 6 directed flow of the heat transfer medium is indicated by arrows that also clarify that the whole heavily loaded lower Area of the peripheral wall 6 from the center to both Sides are rinsed intensively and thus cooled what is in this degree would not be guaranteed if the entire, return water flowing in through the return connection 3, as usual, left to itself and over the whole cross section of the aquifer and only Flow dashed housing 1 upwards could.
- the size of the outflow openings A, the inclination of the Flow guides 10 and the distance of the outflow openings A to the peripheral wall 6 can depend on the special conditions on the respective gas boiler, especially with regard to the expected maximum Thermal loads vary.
- Fig.4 are the flow guides 10 in the form of one in relation to the width B of the heating gas pockets 7 narrower Upflow shaft 12 bounding walls 13 between the Schugaszugtaschen 7 arranged, one part of the Walls 13 as a flow trap 13 'over the return port 3 is arranged, and in the embodiment of Figure 5 are of the walls W forming the flow guides 10 the return-side walls 1o 'in the pocket spaces 7 ', as shown, angled and delimit with the other walls 10 "on the return side those directed against the peripheral wall 6 of the combustion chamber 5 Outflow openings A, i.e. there is an inflow the peripheral wall parts from the side. Also at these embodiments are the ones that arise Currents indicated by arrows.
- FIG. 6 Flow guides 10 in the form of one and / or other side flank F of the Schugaszugtaschen 7 arranged Sheet metal strip 15 formed.
- the metal strips 15 are attached to the flanks F of the hot gas pockets, soldered or welded on. This is done according to FIG on both adjacent flanks of two hot gas pockets, and somewhat offset from each other, so that a kind Labyrinth as flow guide 10 arises.
- Fig. 7 can also a sealing profile on a sheet metal strip 15 15 'can be placed, or it can be used as a flow guide 10 also only one profile 16 (only schematically in FIG.
- the flow guides 10 in the form of itself Form resilient sheet metal profiles 17 and this with their edges R in guide embossments 18 of the side flanks F of the heating gas pockets 7. As from Fig. 9 recognizable and easily imaginable, this creates a real guide channel in each of the pockets.
- Fig. 12 finally illustrates an embodiment of the Flow guidance in the form of a sheet metal comb, the Engage "tines" 20 in the pocket spaces 7 ', this comb or the two combs each to the associated wall 14 is dotted or with this forms part.
- FIGS. 13 to 16 differ from the ones described above in so far as Catching the inflowing water through a lower one Flow baffle takes place through a second flow baffle a cross flow is effected and only then a further cross flow along the bottom of the Combustion chamber peripheral wall 6 and this with increasing Increase in flow velocity.
- This embodiment has proven to be the most effective, which is why this is also preferred.
- FIGS. 16A, B A special feature is shown in FIGS. 16A, B.
- part of the relatively cold return water is branched off and fed directly to the lower cross-flow channel 24, for which purpose separate return lines 3 'are provided in (Fig. 16A) or on (Fig. 16B) housing 1, which cut out part of the return flow to a certain extent and Mix in the hot water in the cross-flow duct 24 and lower its temperature somewhat. If such a boiler is operated in the condensing mode, this is somewhat at the expense of the use of the condensing boiler. Since in the side areas 29 of the housing 1, i.e.
- small catch plates 30 can also be arranged on the side plates with access to the crossflow duct 24 or 24', respectively direct this less hot water into the cross-flow channel 24 or 24 '.

Description
Bekannt ist auch ein Gasheizkessel einschlägiger Art bspw. nach der DE-A-43 01 804, deren topfartige Brennkammern, die mit ihrer Achse allerdings horizontal orientiert sind, mit halbkugelförmigen Gasflächenbrennern bestückt werden, führen zu einer äußerst kompakten Bauweise des ganzen Brennkammerbereiches und insofern auch des gesamten Gasheizkessels, was jedoch mit einer hohen Wärmebelastung der Brennkammerwände verbunden ist, und zwar insbesondere im Bereich der Anschlüsse der nach unten abgehenden Heizgaszugtaschen, deren Anschlußöffnungsquerschnitte die in diesem Bereich kühlbare Fläche der Brennkammerumfangswand entsprechend reduzieren. Durch diese Reduzierung der kühlbaren Brennkammerfläche gleichzeitig in Verbindung mit einer hohen Wärmebelastung und trotz der in der Regel in diesem Bereich zylindrischen Umfangswand der Brennkammer, die an sich ein Abfließen und Auflösen von Siedeblasen erwarten läßt, hat sich gezeigt, daß Siedegeräusche an derartigen Gasheizkesseln, die ansonsten an Leistung und kompakter Bauweise nichts zu wünschen übrig lassen, aufgrund der hohen Wärmebelastung nicht zu vermeiden sind.
