Definitions

  • the invention relates to a water boiler with a combustion chamber heated by an axially arranged burner, which is enclosed by a water jacket formed by two annular, preferably coaxial water chambers, connected to a flow and a return, and permeated by flue gas flues, which has three circumferentially closed walls, one of which the inner wall encloses the combustion chamber and delimits the inner water chamber on the inside, the middle wall separates the two water chambers from one another and the outer wall delimits the outer water chamber, with cavity-forming elements in at least one of the two water chambers protruding to form the flue gas passages protruding with at least one of the Walls forming water chambers are thermally connected.
  • an inner and an outer water chamber jointly form the boundary surfaces of an annular gap which serves to guide the flue gas, which however results in the necessity of arranging water-side supports which are expensive to manufacture and are at risk of corrosion.
  • a hot water boiler is also known from DE-GM 18 89 170, in which the water reservoir is divided into an inner and an outer water jacket by a special design of the flue gas flues. It is disadvantageous that the deflection area of the flue gas duct absorbs a considerable amount of heat from the flue gases, but there is no water-carrying container part adjacent to it.
  • the object of the invention is to avoid these disadvantages with the simplest possible construction of the boiler from robust components.
  • the cavity-forming elements of ribbed profile plates are formed in a water heating boiler of the type mentioned at the outset and fastened to the central wall with the ribbed side, a deflecting plate delimiting the end of the space enclosed by the central wall opposite the burner for the flue gases emerging from the combustion chamber at the same time forms the inner end wall of the outer water chamber having a double-walled cup-shaped profile.
  • the standing water boiler shown as an example comprises a combustion chamber 2 heated by an axially arranged lint burner 1, which is enclosed by a water jacket consisting of two annular, coaxial water chambers 3 and 4, connected to a supply 5 and a return 6.
  • This water jacket is formed by a total of three circumferentially closed walls, namely by the inner wall 7, which includes the combustion chamber 2 and delimits the inner water chamber 4 on the inside, by the middle wall 8, which separates the two water chambers 3 and 4, and by the outer Wall 9, which delimits the outer water chamber 3.
  • rib profile plates 11 are attached to the wall in a heat-conducting manner, protruding into the inner water chamber 4.
  • Such rib profile plates 11 could, however, in the context of the invention - additionally or alternatively - also be attached to other walls of the water heating boiler.
  • the rib profile plates 11 are welded to the wall 8 as cavity-forming elements with the side against which their cavities formed between the ribs are open. Depending on whether they are welded to an outside or an inside of the annular walls, their void-forming, ribbed side is convex or concave. The weld connection is made in the area the edge ribs.
  • the water to be heated first flows from the return 6 into the outer water chamber 3, via upper and lower through openings 12 of the wall 8 shown in FIG. 3 into the inner water chamber 4 and is partly through the wall 7 and partly from those protruding into the chamber 4 , flue gas-carrying rib profile plates 11 heated.
  • the passage openings 12 mentioned are each provided between such rib profile plates 11 in the wall 8.
  • the flue gases are diverted from the combustion chamber 2 via a hot or cooled baffle plate 13 and the inlets 10 'into the flue gas flues 10 and - in counterflow to the direction of the burner 1 - enter the flue gas plenum 14, from where they are discharged via flue pipes, not shown.
