Definitions

  • the invention relates to a standing boiler for the combustion of liquid or gaseous fuels with a burner arranged on the top, the Flame is directed into a flame space open in the flame propagation direction, which is surrounded by a water space and flows downstream into a deflection space, which is connected to a flue gas collecting room via a flue gas duct training stands.
  • a boiler of the above type is for example from the patent DE 195 19 963.4-13 known. This is where the combustion chamber insert, which is open at the bottom, starts Flue gases are diverted into a flue gas duct formation, which directly uses the combustion chamber is comprehensively formed, to which flue gas duct formation radially outwards the water room connects. Heat exchanger fins protrude into the flue gas duct formation inside.
  • EP 0 387 859 B1 according to which particularly low ones Exhaust gas temperatures are achievable and manageable as well as falling below the dew point should not lead to corrosion damage.
  • the invention has for its object corrosion damage by avoiding falling below the dew point with simple construction and simplified maintenance of the boiler ensure.
  • the quickly heated water in the inner water area rises and occurs in the upper water section in a certain order by throttling Outer water space area filled with cooler water, causing mixing he follows.
  • To the outer water area and thus to this by mixing tempered water are connected to the flow and return of the heating system.
  • the Exchange of water between the inner and outer water area is therefore pure by convection and not by forced flow, which would be the case if the heating water would be taken from the inner water area. This keeps the temperature in the Flue gas range remains high even when heating water is drawn off.
  • a buffer effect is created by the two water areas, so that the Exhaust gas temperature with different return temperatures of the water less decreases. A more constant exhaust gas temperature and dew point avoidance are achieved.
  • the flue gas temperature in the boiler is the lowest where the flow temperature is highest.
  • the flue gas duct formation is on the side next to the Flame space arranged so that the preferably from several parallel Flue gas ducts existing flue gas duct formation in total in an adjacent side the flue gas outlet arranged in the burner connection opens.
  • the flue gas ducts consist preferably of tubes with ribs or the like in the tube interior protruding protrusions free inner wall, in particular from smooth-walled overall Pipes. This makes cleaning the flues and the boiler very important simplified. In this design, an elongated horizontal section results, in particular oval outline design of the boiler, thus saving space next to others Arrange aggregates.
  • the transition area is between the two water area areas in the lower section of the water space simply designed by the Partition runs freely down into this section.
  • the partition in the upper section the edge of the water space can be provided with recesses, so that transition openings may remain free in the area of these recesses, if the top edge of the partition wall is face up to the front face of the boiler connects.
  • the upper water transfer is in shape formed by several recesses in the upper edge region of the partition. Out For reasons that will be discussed in more detail later, it can be more advantageous the throttled transition in the form of a single opening in the upper section of the To provide a partition.
  • the partition wall more preferably forms the outer wall of a hollow cylinder, the consists in particular of sheet steel. This makes the partition wall special simple and inexpensive. Regardless of this, the shape of the partition in the Horizontal section depending on the spatial distribution of the Flue gas duct formation in relation to the flame chamber round, polygonal or in particular be oval-shaped.
  • the throttled Transition adjustable, in particular controlled temperature-dependent, for example through a bimetal, such that the flow area of the transition - in the Embodiment thus the one opening or several recesses - with the help adjustable throttle devices.
  • the boiler is preferably made entirely of steel or as a whole Steel structure.
  • the water space engages under the floor of the flue gases from the flame chamber into the deflecting chamber redirecting the flue gas duct formation.
  • the flame chamber and the flue gas duct formation on the hydraulic side Partition put on, which divides the water space into two areas.
  • the inner area between the partition and the flame chamber - possibly with reduced water content
  • Overflow openings in the upper section of the water space and is only due to the The buoyancy of the hot boiler water flows through, so it is independent of that forced flow impressed on the heating circuit.
  • the lift is lower when starting off Water temperature small, which results in a low volume flow and therefore a rapid rise in temperature of the heat exchange surfaces takes place. With increasing water temperature the lift and thus the volume flow increases.
  • the water heats up much faster and stronger than in the outer one Water area that lies between the partition and the outer shell of the boiler and is flowed through by the heating water.
  • the heating takes place by admixing the throttled Overflow openings of the partition from the inner water area and Heat emission from the heated partition.
  • a boiler of the type mentioned so far is, however, in terms of hydraulic management - d.
  • H. the Leading the heating water into the boiler, in the boiler itself or out of the boiler can also be optimized so that the dew point is undershot even at lower levels Boiler temperatures or heating water temperatures and also in one area only lower Utilization should be avoided in any case.
  • this is achieved by that a return of the heating water in the area of the upper water transfer into the outer water space area opens in such a way that the exit impulse of the Return water a mixture of the escaping from the upper water transfer Hot water can be brought about with the water of the outer water area.
  • the returning water is thus targeted or directed into the outer water area initiated that the thereby generated in the outer water area Flow, for example, by sweeping or hitting the heat in the inner water space area emerging from the upper water transfer Hot water causes this hot water with the water in the outer water area and / or optionally also mixed with the return water.
  • the mouth of the return is preferably full, essentially or at least partially or with only one directional component away from the upper water crossing directed. This causes an exit pulse of the return water from the upper water transfer away, so that in the direction of flow in front of this mouth Warm water in the outer water area creates a suction effect.
  • the hot water in the outer area of the water space this leads past the upper water transfer and mixes there with the escaping hot water.
  • the outer water area is (at least) in its upper portion is annular.
  • the return with a Inlet device for loading into the outer water area return water to be introduced with a pulse in the circumferential direction of this is provided in the form of a ring-shaped outer area of the water space, this is due to this exit impulse
  • An annular flow can be achieved in the annular water area. This is particularly so due to the standing arrangement of the boiler in question, because a horizontally directed ring flow can thus occur.
  • the upper water transfer could also in relation to the flow of the Return water and / or in the direction of this in the boiler operation in the outer water area adjusting flow seen downstream of the mouth of the return port arranged, but then the escaping hot water would be directly through the return water flowing in in the vicinity of the upper water transfer is increased Dimensions are cooled. Better mixing and more even temperature distribution in the outer ring area of the boiler - also in the vertical direction achievable in that the upper water overflow upstream of the mouth of the return connection is arranged. Mixed by the suction effect already indicated above then the hot water with that already in the outer water annulus Hot water, in which case part of the hot water / hot water mixture attaches to the Mouth of the return line mixed with the return water.
  • the return water has due to its lower temperature the tendency to flow downwards, so that taking into account this tendency and / or taking into account the fact that the supply of hot water and colder return water to the outside Water area close together, also a vertically uniform temperature is achievable in the outer ring area or outer water area.
  • the return water is the return water to take advantage of its exit pulse just flow into the boiler in the area of the upper water outlet.
  • the return is an inflow baffle or the same line device for guiding the return water from the return port upwards to the return outlet located near the upper water overflow having. If you look at this inflow baffle or line device so that it through leads to the outer water area, the return water can be flushed preheat the hot water in the outer water area.
  • the exit pulse steers available in that the return is part of the outer wall of the boiler trained housing - especially welded to the inside of the boiler outer wall for guiding and introducing the return water into the outer water area and in particular for forming the inlet device and / or the inflow baffle.
  • Such housing can be particularly flat and somewhat wider in an advantageous manner be designed so that a large heat exchange surface between the hot water and the return water is achievable and also between the partition and the Enough free space remains for the hot water.
  • the housing for forming the introduction device has an opening has, the boundary walls at least partially and preferably are directed essentially in the circumferential direction.
  • This mouth opening can for example as an elongated narrow opening - on a side wall of the housing - be trained. So that the mixing of the hot water is ensured preferably only a single water transfer in the upper area of the boiler - namely near the return outlet - trained.
  • this single top Water leakage is located above the housing. On the one hand, this has the effect that the housing is washed by the hot water escaping from the upper water overflow is and thus the return is already preheated in heat exchange manner. To this Way is prevented in any case by a particularly cool return water somewhere in the boiler there is a zone of such low water temperature, that the dew point could be undershot. Second, through this Training an even temperature distribution over the entire vertical axis of the outer water jacket achieved.
  • the mouth opening of the housing is designed such that its boundary walls the return water in the desired direction into the outer water area initiate. Taking advantage of a venturi effect or in the manner of a nozzle is the exit impulse of the return water can still be amplified when the mouth of the return is tapered.
  • the inventive design of the return port allows in the lower area of the boiler, which was previously particularly sensitive to falling below the dew point, achieve an elevated temperature.
  • This in turn causes the temperature profile in the inner water area of the boiler can be raised significantly. This is because that heated water in this inner water area due to the density difference rises up and emerges from the upper water overflow. But then there has to be something new Flow water from the outer water area into the inner water area, what is happening through the lower water crossing. If now in the lower area of the Boiler the temperature is raised, can be in the inner water area this way an increased temperature and a very rapid rise in temperature Achieve commissioning of the boiler.
  • the heating water required for heating does not come from the inside Water area, but taken from the outer water area, so that the temperature of the inner water area essentially due to the overflow of hot water is determined by the upper water transfer and not primarily through more or less large removal of heating water.
  • the heating water withdrawal point of the flow of the heating water in a preferred embodiment also not arranged in the immediate area of the upper water transfer - in Close to this water transfer is the return outlet - rather than it it is envisaged that a flow of the heating water at a point from the upper water transfer in Circumferentially spaced heating water withdrawal point from the outer Water space leads away, in particular for the heating water withdrawal in an upper, the boiler plate - front plate or the outer water space at the top Mounting plate - a removal opening is arranged.
  • the removal of one at the very top arranged location of the outer water area is advantageous because there due to the hottest water accumulates in the outer water area.
  • a possible ring flow in the outer water area, which can be achieved by the exit impulse of the return water is hardly disturbed.
  • This ring flow has the particular advantage that a Formation of hot nests in the entire boiler area, but especially in the upper one Area, the connecting seam between the separating jacket and the upper boiler plate or Mounting plate, is counteracted.
  • a flow connector could also directly connect to this removal opening, however, this is unwieldy in terms of assembly.
  • the supply and return connections are close to each other, so that the Pipe connections together - especially to a common pipe connection, control and Pump element - can be connected.
  • the lead a flow channel for connecting the removal opening with one on the same Boiler side as the return pipe - preferably in the vicinity and in particular above it - arranged flow connector.
  • the partition is provided with an indentation in the area of this removal point, a larger opening cross-section can be reached. It could also be a larger one Part can be removed from an area within the indentation, so that the ring flow otherwise leading around the separating jacket is less disturbed.
