Definitions

  • the invention relates to a boiler according to the preamble of the main claim.
  • Such boilers with Schutskon in the water-carrying interior of the boiler housing are generally known and make the connection from the combustion chamber to the Schugasabzug or to the Rauchgassemmelhunt with deduction.
  • Such heating gas draft pockets are either arranged in a plurality, but separately, between the combustion chamber and the extraction area, or such pockets are combined to form a pocket block which is then arranged as a whole between the combustion chamber and the extraction area.
  • the invention is therefore based on the object to improve a boiler of the generic type with respect to the pockets in such a way that with a simple manufacture and easy integration of the pockets into the boiler housing and with the most extensive surface structure in the form of wave embossing and the associated increase in transmission area on the one hand the lowest possible flow resistance on the gas side should be achievable in the pocket to be designed with external pressure stability and, on the other hand, there should not be any embossing protrusions on the side surfaces that hinder the inflowing water, and the whole is connected with the proviso that with the possibility of swirling the entire gas volume flowing through, the greater part of the heating gases flowing through in the central plane of the pocket To find an exchange opportunity.
  • the demands made are met overall. Since the wave embossments are directed only into the interior of the pockets, the pockets which are to be arranged parallel to one another can be assigned to one another in relatively close proximity without there being any obstacles in the form of outstanding wave embossments in the upstream path of the water. As a result, there are no spaces inside the bag, based on the inflow and outflow cross-sections, into which the heating gas flowing through would have to expand.
  • the entire size of the side walls for the wave embossing is used, the relatively narrow, embossed edge areas on the one hand allow easy integration into the boiler housing and on the other hand easy closing or folding of the pocket along the narrow side edges. Since the wave embossing, which is only directed inwards, practically covers the entire side walls and intersects, there are a large number of mutual support points for the two side walls in the entire longitudinal center plane of the pocket.
  • the embossments are only directed inwards, there is no expansion of the inflowing heating gases in the pocket in relation to the inflow cross section free of embossments, but rather a one-time compression on the inflow side to the available wave embossing cross sections, the heating gases essentially having their wave embossing continue to flow and only mix to a certain extent in the interface area of the longitudinal median plane of the pockets. Since the embossments are inclined with respect to the longitudinal edges of the pockets, a change to the other flow level of the pocket takes place to a certain extent only at the ends of the wave embossments, which do not extend with their total length from the inflow opening to the outflow opening.
  • the associated resistance is reduced, however, by the fact that these alternating areas are free from wave embossing, which results in cross-sectional small, but not inclined, flow channels at the longitudinal edge areas in the pocket.
  • the number of corrugations extending from the inflow to the outflow opening with its entire length is kept larger than the number of shorter corrugations.
  • the degree of inclination of the wave embossments depends only on whether the pockets are rather long than wide or rather wide than long in consideration of the space available for this in the water-carrying housing.
  • the pockets of the boiler according to the invention are not readily comparable, since such heat exchangers, as far as is known, are only formed from several stacked plates, while in the present case the gas-carrying pockets, even if they are combined as a pocket block, only the water-carrying ones Pass through the space in the boiler housing as separate heating gas flues.
  • the special design of the boiler according to claim 4 leads to an extraordinarily favorable effect with regard to a reduction of the flow resistance with at least comparable heat transfer performance. Hence, this is due to the fact that some of the heating gases find the direct path from the inflow side to the outflow side, but there are still turbulence areas when passing through the intersecting passages or wave embossments, and another part of the heating gases with the same turbulence effect also and inevitably change the direction of flow in the edge areas of the drawstring and also change the flow level. In order to be able to achieve a comparatively low flow resistance in bags of conventional type, it would be necessary to create the wave embossments much deeper.
  • the heating gas draw pocket is designed such that the greater part of the wave embossings occupies two thirds and the smaller part a third the inflow or outflow opening of the pocket.
  • the greater part of the wave embossing which takes up the two thirds division, runs continuously from the inflow opening to the outflow opening of the pocket, while the other part of the wave embossing, which inevitably corresponds to the Relay of the longitudinal extent, practically forms a total of triangular surfaces with respect to the side walls of the heating gas draw pockets, so that the heating gas part flowing therein changes its direction in the respective edge region of the heating gas draw pocket and also has to change the "flow level".
  • the hot gas train pocket consists of two side walls 1 with shape and course-identical wave embossments 3, which are mirrored together with wave support on the opposite and hot gas side at the intersection points 5 and gas and. Along their longitudinal edges 4 bent in the flow direction are connected to each other in a liquid-tight manner.
  • the wave embossments 3 are embossed into the side walls 1 such that the wave embossments 3 end shortly before the edges of the inflow and outflow openings 7, 8 of the pocket 2. This simplifies the installation of such pockets in the bottom wall 14 provided with corresponding openings in a combustion chamber, not shown here, as shown in FIG. 6.
  • the heating gas draw pocket 2 is advantageously designed in such a way that in the area of the longitudinal edges 4 there are no wave embossments 3 in both side edges, which results in non-inclined flow channels 16 running in the flow direction, in which the wave embossments 3 of the Open out parts II.
  • This measure also reduces the flow resistance in the edge regions without, as has been shown, the aforementioned directional changes tion of the heating gases flowing there and the change of the "flow floors" is significantly impaired.
  • the fields of the wave embossing 3 can, unless an appropriately large embossing tool is used, be produced with the same embossing tool that is only the size of one embossing field, since the other field has the same wave embossing profile.
  • the two halves of the sheet metal blank 11, which represent the side walls 1, are folded or bent along the dash-dotted line, as a result of which the corrugated embossments 3 come to lie on the other half with an opposite slope.
  • the edges 6 surrounding the embossing fields, which form the narrow side walls 6 in the finished and closed state of the pocket are dimensioned such that their width corresponds approximately to a wave depth T.
  • the middle, unembossed stripe has twice the width T and the two unembossed stripes, which form the inflow and outflow opening 7, 8 on the finished pocket, also have a width of about one wave depth.
  • FIG. 8 different arrangement options for the heating gas draw pockets 2 in the water-carrying housing 18 of different types of boilers are shown in FIG. 8, wherein the hot gas draw pockets 2 are grouped together separately or as a block, each extending from the bottom 14 of the combustion chamber 19 to the exhaust area 20.
