Definitions

the invention relates to a three-pass boiler, consisting of a water-carrying housing with a combustion chamber, deflection chamber and, starting from this, with a third train leading to the exhaust gas connection.
Such three-pass boilers are well known and in use, so that no special printed evidence is required in this regard.
the three trains can be realized in different ways, which ultimately depends on whether it is a reverse combustion chamber or a combustion chamber open at the rear, from the rear open end of which the heating gases flow forward to the deflection chamber, from which in all cases such boilers, the heating gases flow into the third train, which can either be arranged above or below the combustion chamber.
Special measures double-shell additional heating surface
condensing boilers i.e. at least with partial condensation of the exhaust gases
the invention is based on the simple task of redesigning such three-pass boilers for condensing boiler operation and thus the annual efficiency without major changes to the previous three-pass boiler designs further increase.
this third train consisting of a plurality of individual pipes, is designed as a finished installation unit and welded into the boiler, that is, practical for the final assembly no greater effort than when installing a previously large diameter tube forming the third train.
the three-pass boiler is designed such that the tubes are arranged in a circular arrangement as a tube package running above the combustion chamber and are welded at their ends into connecting flanges made of likewise condensate-resistant material and these flanges are welded into corresponding openings in the front and rear walls of the housing , wherein the flue gas connection also formed from condensate-resistant material can be formed as an integral component of the flue-side connection flange.
tubes are arranged below the combustion chamber on a circular arc concentric to the combustion chamber axis and with their ends on the exhaust side reach through the rear wall of the housing in a liquid-tight manner and open into a condensate-collecting chamber made of condensate-proof material with an exhaust gas connection and condensate drain attached to the ends.
the change effort is minimal, especially since the assembly of pipes with the condensate collection chamber can be inserted and welded from the discharge side into corresponding openings in the rear and front walls of the housing. Moreover, it is also possible here to weld the ends of the tubes into connection flanges made of condensate-resistant material and these flanges into corresponding openings in the housing front wall 8.
the three-pass heating boiler consists in both cases of the illustrated embodiments in a known manner from a water-carrying housing 12 with combustion chamber 6, deflection chamber 13 and, starting from this, with a third train 1 leading to the exhaust gas connection 5. It is essential and common for both embodiments that the third train 1 is formed from a plurality of small-diameter pipes 2 made of condensate-resistant material, which are guided from the deflection chamber 3 with a gradient to the exhaust gas connection 5 provided with a condensate drain connection 4.
the tubes 2 are arranged in a circular arrangement as a tube package 2 'running over the combustion chamber 6, at their ends in connecting flanges 7 made of material which is also condensate-resistant, and these flanges 7 in corresponding openings in the housing front and rear walls 8, 9 shrink wrapped.
flanges 7 made of material which is also condensate-resistant
the flue gas connection 5 which is also made of condensate-resistant material, is formed as an integral component of the flue-side connection flange 7 ', that is, this flue gas connection 5 is placed as a piece of stainless steel pipe on the correspondingly dimensioned connection flange 7' and with it welded, after which this entire assembly is inserted into the housing 12 and welded to it (see also FIG. 6A).
the tubes 2 are arranged below the combustion chamber 6 on a circular arc 6 "concentric to the combustion chamber axis 6 'and, with their trigger-side ends 10', reach through the flange 7 inserted in the housing rear wall 9 in a liquid-tight manner
the ends 10 'projecting beyond the rear wall 9 open into the condensate collection chamber 11 made of condensate-resistant material with an exhaust gas connection 5 and condensate drain 4.
This condensate collection chamber 11 results with respect to its cross-sectional shape from Fig. 5.
the flanges 7' on the exhaust side are related their area sizes advantageously dimensioned larger than the front flanges 7 in order to be able to insert the structural units without problems.
