Definitions

  • the invention relates to a burner-heated device, in particular a water heater, with a heat exchanger arranged in the exhaust gas routing of the burner leading to a chimney or similar exhaust gas outlet, through which exhaust gases from this burner flow, and a combustion chamber located below the heat exchanger.
  • a boiler with these structural features is known from DE-OS 3604842.
  • the flue gas temperature is to be adapted to existing chimney systems in such a way that the flue gas flow is divided into a main flow flowing through the main heat exchanger and a secondary flow at least partially bypassing it.
  • the disadvantage here is that only a certain increase in the exhaust gas temperature that cannot be changed subsequently can be achieved in this way.
  • Another problem is the adaptation of the boiler to possibly very different structural conditions of the chimney.
  • the object of the invention is to prevent condensation forming in the chimney as a result of the temperature falling below the dew point. Such condensation forms a gradual sooting of the chimney, which destroys the chimney wall and forces its costly renovation.
  • the invention is based on the knowledge that, in order to prevent this condensate formation, an increase in the temperature of the exhaust gases that is sensitive to the respective local nature of the fireplace is required, provided that the fireplace, as in old buildings, for example, is not optimal and therefore at comparatively low exhaust gas temperatures tends to soot.
  • a bypass guide which opens directly into the chimney or the like and bypasses the heat exchanger is branched off, in which the size of the throughput of the portion to be supplied directly to the chimney the exhaust gas regulating control element, for example a slide valve or throttle valve, is arranged.
  • This portion can therefore be selected and adjusted as desired, so that the temperature of the exhaust gases flowing through the chimney or similar exhaust gas outlet can be adjusted to an optimum value above the dew point, at which, on the one hand, no condensate formation is to be feared, but on the other hand there are no excessive heat energy losses.
  • the heat exchangers of devices of the type mentioned at the outset are known to be supplied with the device in which they are installed as standard and are dimensioned uniformly, regardless of the installation location. Thanks to the solution according to the invention, the exhaust gas temperature of such devices can now be set individually to the respective local nature of the fireplace with little expenditure of time and effort so that the exhaust gas temperature within the fireplace does not fall below the dew point and, consequently, no condensate is produced.
  • bypass guide is expediently arranged essentially parallel to the exhaust gas guide containing the heat exchanger.
  • the bypass guide can easily be formed by the components of the heat exchanger, for example the members of a sectional boiler, but this bypass guide can also be conducted separately and at a distance from the exhaust gas guide containing the heat exchanger from the combustion chamber of the burner directly into the exhaust gas collecting chamber .
  • the adjustable control element arranged in the bypass guide for example a slide, a throttle valve or the like, the portion of the uncooled exhaust gases to be fed directly to the exhaust gas outlet and the chimney can be conveniently and easily adjusted to its optimum size.
  • the capacity of the initially uniformly dimensioned heat exchanger can be purposefully changed and optimally adjusted, taking into account the respective local conditions and the nature of the fireplace, in order to solve the initially defined task.
  • a partial area of the surface of the heat exchanger has little or no fins, so that uncooled exhaust gases can reach the chimney to a measurable extent within this area.
  • some of the fins can be used to measure the heat absorption capacity as required of the heat exchanger to be releasably connected to the tubes carrying them.
  • the tubes carrying them In order to then increase the flue gas temperature in the chimney to a level sufficient to prevent condensation, only a variable number of such releasable fins need to be removed, or only so many releasable fins can be used in a finned-free area of the pipes that the exhaust gases in this partial surface area do not cool down significantly, at least not below the dew point.
  • the fins can be plugged onto the pipes and releasably connected to the pipes by frictional engagement.
  • a detachable slat In order to prevent such detachable slats from being arranged too closely, which would cause locally excessive temperatures and poor heat transfer, a detachable slat should be insertable between two or more stationary slats.
  • Another possibility for realizing the inventive idea is to make walls of the fins extending between adjacent tubes removable in some areas, in order to reduce their heat-transferring area as required and to be able to increase the temperature of the exhaust gases leaving the heat exchanger.
  • punched-out sections can be provided in these lamellae, preferably punched-out paired angles to separate approximately triangular or trapezoidal wall parts.
  • the throughput of the exhaust gases can be throttled by a part of the heat exchanger to increase the temperature occurring in the chimney as required.
  • this wall can only extend over part of the distance formed between adjacent slats or over the full distance. In the latter case, the wall can also extend over several distances formed between adjacent lamellae.
  • the extent of the blocking of the heat exchanger can therefore be regulated extremely sensitively within the scope of the invention with very simple measures in order to achieve an exhaust gas temperature in the chimney which prevents its sooting, on the other hand, it does not result in excessive energy losses.
  • the inner edge of the fins facing the heat exchange tube has a collar attached to the tube wall, it is advisable to have the wall attached to the outer edge of these fins point to the side opposite this collar.
  • the heat exchanger consists of a block of heat exchange tubes through which the fins pass, then it is advantageous to attach the walls to the fins in the edge region of this block.
  • At least one cover plate arranged on the heat exchanger for example a heat-resistant sheet metal plate, is provided, which extends over, preferably opposite, edge regions or the central region of the surface of the heat exchanger .
  • the surface area to be covered with such a plate optimal from case to case, in which, on the one hand, a drop below the dew point in the chimney or the like is avoided, but on the other hand the losses of exhaust gas heat are still justifiable, can either be determined from the outset for the locally specified conditions or can be fixed by a fixed installation of the cover plate, or such a plate can be arranged in an adjustable manner to prevent the throughput of the exhaust gases, in order to be able to fix it in a throttle position that can be optimally selected as required. In any case, such a cover plate can always be retrofitted to an existing heat exchanger without any problems.
  • cover plates on the heat exchanger is fundamentally arbitrary within the scope of the invention, that is to say they can extend over the edge regions of the heat exchanger, for example be arranged laterally, at the front and / or rear of the heat exchanger, for example also in adjacent edge regions.
  • the plates are adjustable to regulate the extent of the throttling as required, it is advisable to mount them so that they can be easily pivoted about a horizontal axis.
  • the gas-fired devices with a heat exchanger, the efficiency of which corresponds to the optimal condition of the existing fireplace or similar flue gas extraction, and then to increase this efficiency at the installation site of the device by setting or dimensioning the cover plate (s) Reduce that a drop below the dew point in the chimney is reliably prevented.
  • the exhaust gas temperature within the exhaust gas outlet can be adapted, namely reduced, to its new state at any time.
  • At least one edge region of the heat exchanger can be covered by at least one insert arranged on its underside in the upper part of the combustion chamber.
  • Such an insert can advantageously contribute to the insulation of the combustion chamber and thereby reduce the heat loss in this area and increase the temperature of the exhaust gases flowing off.
  • the insert attached to the preferably cooled and / or insulated wall of the combustion chamber can have a width that increases upwards against the heat exchanger and covers an edge region of the heat exchanger.
  • the top of the heat exchanger preferably within an exhaust manifold, has baffles which, due to their surface, shape and installation position, allow the absorbed radiation to be emitted and the incident heat to be reflected in the exhaust gas stream, thereby increasing the exhaust gas temperature.
  • a baffle directed diagonally upwards against the inlet of the chimney or exhaust fume and / or a baffle arranged at a distance from the inlet of the chimney or exhaust fume, which has a transverse to its axis, allows a flow to occur within the exhaust gas collector, which favors the absorption of the radiant heat and also a uniform flow of the upstream heat exchanger guaranteed.
  • the exhaust manifold can advantageously be insulated to reduce the temperature of its outside, most simply by designing its hood with two shells up to the exhaust gas outlet, in order to thereby reduce the radiation and to ensure high exhaust gas inlet temperatures in the exhaust gas outlet.
  • the inner shell can then be designed in such a way that it fully takes over the function of the above-mentioned guide plates.
  • a plate which is divided into lamellae can be inserted, preferably inserted, into the exhaust gas duct and is used for heat absorption and radiation, and / or a frame fitted with lamellae, which enables the exhaust gas temperature to be corrected according to the nominal heat output that is set , namely by reducing or increasing the free exhaust gas flow cross section and thus the heat transfer surface of the heat exchanger.
  • the plate and the frame are assigned to one another, at least one of the two parts being displaceably mounted in relation to the other part within the exhaust gas duct in order to be able to measure the flow cross section in a targeted manner.
  • a bypass for part of the exhaust gases flowing through the exhaust gas duct is provided on the side of the heat exchanger and the above-mentioned plates or frames in the exhaust gas duct, through which this portion reaches the chimney without flowing through the heat exchanger.
  • a water heater shown for example in Figures 1 and 2 consists essentially of the burner 1, e.g. a gas burner, and from a heat exchanger 3 arranged in its exhaust duct 2, which e.g. pipes, plates or the like, water-carrying members, which are equipped with ribs, needles or the like.
  • the organs favoring the heat exchange can consist of limbs, the outside of which are washed around by the exhaust gases.
  • a regulating member 10 for example designed as a slide, is provided at the outlet of the bypass guide 9, according to FIG. 2, however, there is an adjustable throttle valve as a regulating member 10 in the bypass guide 9.
  • control elements 10 can be carried out within the scope of the invention when the device is installed, depending on the nature of the locally existing fireplace, but it could also, if necessary automatically controlled, depending on the temperature the flue gases in the chimney can be controlled depending on the operating and / or time or depending on other physical parameters.
  • the bypass guide 9 can be designed as desired within the scope of the invention.
  • it can consist of components of the heat exchanger, e.g. be formed by the links of a link boiler and consist of castings of such links.
  • this bypass guide 9 can also be guided separately and at a distance from the exhaust gas guide 2 containing the heat exchanger 3 from the combustion chamber 8 of the burner 1 into the exhaust gas collecting chamber 4.
  • the task defined at the outset of increasing the exhaust gas temperature in the chimney as required can also be achieved within the scope of the invention by a targeted reduction in the heat absorption capacity of the heat exchanger.
  • FIG. 3 shows a heat exchanger 3 with a family of parallel water-carrying pipes 11 which are covered with fins 12. At the opposite ends of these tubes 11 there is on the one hand a distributor 13 and on the other hand a collector 14 to which the return 7 or the flow 6 of a heating circuit connect.
  • the exhaust gas of the burner-heated device flows through this heat exchanger 3 upwards in the direction indicated by an arrow to the exhaust gas collector and to the chimney.
  • a partial surface area 15 of the total area of the heat exchanger 3 is designed to be lamella-free, and in this area 15, fins 16 which can be plugged on as shown in FIG. 4 can be attached can be attached to the tubes 11 in any number.
  • these fins 16 are only plugged on, they do not serve fully, but only partially for heat exchange. Above all, however, they reduce the free cross section for the throughput of the exhaust gases.
  • the heat exchange capacity of the heat exchanger 3 can thus be fine-tuned to the respective local nature of the fireplace or the like.
  • the heat of the exhaust gases coming into the chimney or the like is influenced by the respective size of the area 15 which remains free of lamellae and through which part of the exhaust gases flows largely uncooled to the exhaust gas collector and which can be reduced or reduced as required from case to case by inserting the releasable fins 16 can be enlarged as desired by removing existing detachable slats 16.
  • wall parts 18 of the fins 12 extending between adjacent tubes 11 can be removed if necessary, punched portions 19 of the fins 12 running in pairs and at an angle to one another being provided to facilitate the separation of such approximately triangular wall parts 18.
  • a further, transverse punching 20 serves to facilitate the handling of the wall parts 18.
  • water-carrying heat exchange tubes 11 are equipped with fins 12 which run parallel to the flow of the in a Exhaust gas duct 2 are aligned from a combustion chamber of a burner-heated device to a chimney-flowing exhaust gas.
  • the lamellae 12 have collars 21 with which they are fastened flat against the pipe wall.
  • the exhaust gas flow runs vertically upwards, but could also run vertically downwards or horizontally in the case of a fan-operated burner.
  • the fins 12 have - in the direction of the exhaust gas flow downstream - edges 22 and - in the direction of the exhaust gas flow upstream - edges 23 which face the combustion chamber.
  • the edges 22 are accordingly at the top and the edges 23 at the bottom.
  • the fins 12 are made of copper or stainless steel in the same way as the tubes 11. Each lamella 12 is penetrated by a plurality of tubes 11 which are parallel to one another. In this way, the fins 12 of the heat exchanger 3 form a block, which is delimited on the long sides by a frame 24.
  • These walls 25 can be formed in the simplest way by flanges attached to the edge of the lamellae 12. These flanges can be arranged both on the edge 22 facing the combustion chamber, ie upstream of the exhaust gas flow, according to FIG. 7, and on the edge 23 facing away from the combustion chamber, i.e. downstream of the exhaust gas flow, according to FIGS. 8 to 10.
  • the wall 25 attached to their outer edge should point towards the side opposite this collar 21 thereby strengthening the stability of the lamella 12.
  • FIGS. 7 to 9 show embodiments in which the walls 25 extend only over part of the distance between adjacent slats 12, these walls 25 run according to FIG. 10 over the full distance and over several slats 12, so that they are some between these slats 12 completely close the spaces 26 formed and block them for the exhaust gas flow. According to FIG. 10, these walls 25 can therefore also extend over a plurality of lamellae 12.
  • Water to be heated is fed to the lamella block according to FIG. 7 via the return 7 of a heating circuit, which passes through the distributor 13 into the heat exchange tubes 11 and flows through the exhaust gas duct 2 in these tubes 11 and passes via the collector 14 into the flow 6 of the heat exchanger 3.

  • a cover plate 27 is placed on the top of a flat heat exchanger 3, which covers the four edge areas in a surface area that can be selected as required and thereby blocks the throughput of the exhaust gases in these edge areas, thus reducing the heat absorption capacity of the heat exchanger and the cooling of the exhaust gases.
  • this cover plate 27 are to be chosen from case to case in such a way that the exhaust gas temperature above the heat exchanger 3 only increases to such an extent that a drop below the dew point in the chimney or the like and, as a result, the formation of condensate there is reliably prevented.
