Definitions

  • the invention relates to a three-pass boiler according to the preamble of claim 1.
  • Such three-pass boilers are known, for example, from EP-A-0 616 173 A2 and according to FIG.
  • Dreizugsammlungkessel are actually defined as such and illustrated return ports in the middle of the boiler housing, in transition openings between a shielded by a baffle, the second and third train receiving first space and the remaining water-carrying space of the boiler housing.
  • the baffle extends horizontally through the entire water-bearing space of the boiler and is provided in the area below the heating circuit flow connection with openings.
  • a storage circuit supply connection is under penetration of the baffle with the first room in direct connection.
  • DE-A-84 14 084 U1 a Zweizugsammlungkessel is known in which a the confluence of the burner side top return connection dimming, over more than half the length of the boiler extending shield is provided with holes.
  • the invention is based on the object, the admixture from hot boiler water to colder return water with simple means to intensify and shield to the actually relevant return area concentrate to the remaining area of the secondary heating surfaces unhindered for direct heat exchange between keep this and the heat transfer medium open.
  • the Dreizugsammlungkessel consists of FIG. 1, as before even, from a water-bearing, with supply and return connections 5, 6 provided housing 4, in which a with Burner 1 '' equipped combustion chamber 1 'as the first train 1, a relative to the combustion chamber 1 'opposite permeable second train 2 and one of several Schugaszugrohren 3 ' formed, the Rauchgasabzug R leading third train 3 arranged and the second and third train 2, 3 of a provided with openings baffle 7 are shielded.
  • Figs. 1 and 2 are in the apex portion 11 of the curved Baffles 7 small holes 8 shown by the a certain part of the pressurized return water is added to the already heated boiler water.
  • This per se known hole arrangement serves a Part of the return water directly with the heated boiler water to mix. Since this is a comparatively small amount is, on the one hand, due the still hot flues in this area no danger the condensation, on the other hand is through this Return feed through the holes 8 inevitably the hot water outlet from the openings 9 or slots up to intensified to a certain degree. That through reach this boiler or special baffle training - bare result is shown in Fig. 3. In comparison to Fig.
  • thermography (usually colored) of comes from a three-pass boiler of normal design is out 3 clearly shows that there the condensate-preventing temperature range TB (crosshatched) pushed much deeper is, that is, in the area behind the Return region extending parts of the second train. 2 and the lowest parts of the third train 3 are no longer reached by the cold return water.
  • baffle. 7 in that in the apex region 11 of the return flow 5 to the boundary wall 12 of the overflow chamber 4 'towards a a portion of the return water to the boundary wall 12th conductive slot opening 13 is arranged.
  • FIGS. 5, 6, are two different Embodiments of baffles 7 show.
  • the baffle 7 according to Figure 5 points in this case at both edges against the housing wall, not shown in these FIGS. 5, 6 W bent webs 7 'on, while the other, in 6 illustrated baffle 7 to the boundary wall 12 of Overflow chamber 4 'towards no such web 7' has and with its undeformed edge R directly against the boundary wall 12 has encountered.
  • the webs 7 'and the edge R are used in case production only by tack welding on the housing wall W or in the case of FIG. 6 with respect to the edge R fixed to the boundary wall 12.
  • baffle training is the essential slot opening 13 in the case of Embodiment of the baffle 7 in the boundary wall side Web 7 'arranged ( Figure 5) and in the case of the embodiment 6, as shown, directly in the baffle edge R.
  • the slot openings 13 in the To produce way that the web 7 'and the edge R of the Leitbleches 7 only two cuts and thereby resulting metal sheet bends vertically downwards, as indicated by dashed lines in Figure 6.
  • the apex area 11th of the baffle 7 is not bent but in required Width to form a flat surface.
