Definitions
- the invention relates to a three-pass boiler according to the preamble of claim 1.
- Such three-pass boilers are generally known and in Use, so there is no special in this regard Written evidence is required.
- This serves on the burner side arranged in the water-carrying part of the housing and the second and third train shielding baffle to that flowing back from the return connection into the boiler housing, relatively cold water outside around these two Guide trains around and shield them against the return.
- the exhaust gas temperatures are still high in both trains enough to have a condensation or Condensation to exclude.
- the return water is therefore from the baffle first in the burner-side area of the first train, i.e. led to the combustion chamber and heated there. After that the return water flows into the exhaust gas area of the second and third train, in which the heating gases are already have cooled, so that there is the risk of condensation and so there is corrosion.
- the invention is based on the object on three-pass boilers of the type mentioned in the introduction formation of condensate, especially in the third heating gas flue, specifically here in the part that is located deepest in the boiler housing, on simple Way to rule out as far as possible.
- an advantageous further development consists in that the openings in the baffle in the form of slots are trained, since this is the easiest way to cover the entire width of the baffle is to be recorded.
- the outflow openings are also advantageous with this solution provided with so-called guide plates, which, oriented and inclined downwards from the baffle and the housing wall protrude limited return gap.
- This Design of the outflow openings with guide plates as a result that flowing past the guide plates, relatively cold return water, which is usually under the Pressure of a circulating pump fed into the boiler housing a suction on the much hotter boiler water exercises under the baffle and this injector-like sucks out the inner boiler area.
- These guide plates are easiest and most convenient by form-matching Punching on the baffle and deflection gained.
- the three-pass boiler according to the invention is as follows based on the graphic representation of exemplary embodiments explained in more detail.
- the three-pass boiler according to Fig.1, as before already, from a water-bearing housing 4 with a front and Return connections 5,6, in which a burner equipped with 1 '' Combustion chamber 1 'as the first train 1, based on the combustion chamber 1 'can be flowed through in the opposite direction Train 2 and one consisting of several heating gas pipes 3 ' and flowable in the same direction as the combustion chamber 1 ' third train 3 are arranged, the second and third train 2, 3 in the area of the burner 1 ′′ from, as shown, form-fitting curved guide plate 7 shielded are, whose apex line 7 'is located centrally under the return connection 6 extends.
- Fig.1.2 essential that the baffle 7, based on the Medium perpendicular MS, in the middle area of its curved Legs 7 '' arranged over their width B distributed Openings 9 is provided.
- FIGS. 5, 6, the two different ones Embodiments of guide plates 7 show.
- the guide plate 7 according to FIG. 5 has on both edges against the housing wall, not shown in these Fig. 5,6 W bent webs 7 ', while the other, in Fig.6 shown guide plate 7 to the boundary wall 12 of the overflow chamber 4 'has no such web 7' and with its undeformed edge R directly against the boundary wall 12 encountered.
- the webs 7 'and the edge R are only used in the manufacture of housings by tack welding on the housing wall W or in the case of Fig. 6 fixed with respect to the edge R on the boundary wall 12.
