Definitions

  • the present invention relates to a fuel-heated water reservoir according to the preamble of the main claim.
  • Such fuel-heated water storage tanks are generally used to heat warm service water. They have a hollow cylindrical water reservoir, the center of which is formed by a flame tube which is swept by exhaust gases from a burner that heats the water reservoir.
  • a fuel-heated water storage device for feeding a central heating system, it has already been proposed to insert a pipe coil into the water storage device which is connected to the central heating system.
  • the disadvantage here is that the total hot water content must be heated before hot water can be delivered to the central heating system.
  • Such a water reservoir has become known from CH-A-382 203. It has a central firebox below, into which a lintel burner protrudes. A flame tube is arranged above the combustion chamber, through which the exhaust gases can withdraw. The flame chamber is surrounded by an annular space containing heating water, which is divided into two partial annular spaces by a vertical baffle, which are freely connected at the top and bottom. The return connection of the heater opens at the bottom, approximately at the level of the end of the lintel burner, and the flow connection of the heater opens at the uppermost point of the annulus mentioned. The annulus is in turn surrounded by another annulus, which represents a domestic hot water tank.
  • This annular space is flushed on its front underside and on the inside of its jacket by the heating water and is heated by it.
  • the temperature of the heating water inevitably corresponds approximately to the domestic water temperature.
  • a thermal separation of the two temperatures is hardly possible, since the heating water must be circulated in the annular spaces to transfer heat from the burner gases to the process water.
  • a hot water boiler is known from NL-A-6 516 660, which is designed as a horizontal cylinder.
  • the central interior is formed by a flame tube, which is surrounded by an annular space that heats the water in a central heating system.
  • the jacket of this annulus is provided with fins, which in turn serve to transfer the heat originally given off by the burner to the heating water to the service water.
  • the temperatures of the heating water and process water are linked to each other, since the former is used as a heat transfer medium.
  • FR-A-2442408 shows an upright cylindrical water reservoir with a central flame tube which is traversed by exhaust gases from a burner arranged below. Annular spaces are arranged directly around the flame tube, which serve to heat water in a central heating system. Here, too, it is necessary to first heat the water in the central heating system before the heat can be transferred to the domestic water. This also results in a thermal coupling between the attainable temperatures of the process water and the heating water.
  • the present invention is therefore based on the object of preventing this thermal coupling between the temperatures of the process water and the heating water during heating operation.
  • the invention proposes the features evident from the characterizing part of the main claim.
  • the figure shows a schematic longitudinal sectional view of a gas-heated storage.
  • the gas-heated storage tank has a housing 1 provided with an insulating layer, which consists of a cylinder jacket 2, a base plate 3 and a cover plate 4 provided with recesses, which are tightly connected to one another on all sides.
  • the central interior of the housing 1 is formed by a flame tube 5, to which a gas burner 7 is assigned at its end 6 which widens below and is fed via a gas line 9 provided with a fuel solenoid valve 8.
  • gas instead of gas as an energy source, oil or a solid fuel could also be used.
  • the wall of the flame tube forms a heat exchanger to form a double annular space 10 which extends around the cylinder jacket of the flame tube and which forms two legs 11 and 12 which are separated from one another by a separating plate 13 and have the shape of a U with a deflection 14 located at the bottom in the burner area .
  • a flow line 15 is connected in the area of the cover 4, in which a circulation pump 17 driven by a motor 16 and a three-way switching valve 18 are arranged, which can be adjusted by a servomotor 19.
  • the motor 16 or the servomotor 19 are connected via a control line 20 to a regulating and control device 21, which controls the solenoid valve to the burner 7 via a line 22 and to which a temperature sensor 24 is connected via a measuring line 23, which in the interior 25 of the Water storage is arranged.
  • the flame tube 5 and the double annulus 10 form cylinder or annular cylinder spaces lying concentrically to a common axis of symmetry.
  • a further annular space 26 extends around the double annular space 10 and is separated from the double annular space 10 by a third annular space 27.
  • the individual annular spaces 26, 27, 11 and 12 are separated from one another by annular plates 28. While the third annular space is connected to the atmosphere via an annular recess 29 in the area of the cover, the further annular space 26 is connected to a connection of the three-way valve 18 via a return line connection 30 - likewise provided in the area of the cover 4.
  • a flow line 31 leads to a consumer, not shown, which can consist of a series and / or parallel connection of a plurality of radiators and which is connected on the return side to a return line 32, the connecting piece of which in the area of the cover in the outer leg 12 of the double annulus 10 opens.
  • the interior 25 of the water reservoir 33 extends around the further annular space 26 and is delimited inwards by the separating plate 28 of the further annular space 16 and from the outside by the jacket 2 of the housing 1.
  • a connecting line 35 is provided, which extends approximately from the lowest point of the further annular space 26 to the deflection point 14 between the two legs 11 and 12 of the double annular space 10. Both the legs 11 and 12 and the annular spaces 26 and 27 expand in the lower region 34, as does the interior of the flame tube 5. This expansion is at the expense of the interior 25 of the water reservoir 33, which does not extend down to the region of the base 3, but instead ends at a distance from it.
  • a cold water supply pipe 36 opens into the lower area of the interior 25, from which a service water tap pipe 37 branches off in the uppermost area.
  • the inside of the further annular space 26 facing the third annular space 27 can be provided with an insulating layer 38.
  • the temperature sensor 24 is arranged in the lower region 34 of the interior 25 of the water reservoir 33.
  • the fuel-heated water storage tank has the following function: If this storage tank is only used to prepare warm service water. and the temperature sensor 24 requests heat, so result from the control and regulating device 21 control signals for opening the solenoid valve 8, for starting the motor 16 of the circulating pump 17, for adjusting the three-way valve 18 in such a direction that the flow 31 is shut off.
  • the burner starts up and draws in fresh air through the air opening 29 and the third annular space 27.
  • the exhaust gas generated by the burner 7 rises in the flame tube 5 and leaves the water reservoir via an exhaust pipe, not shown, in a continuation of the flame tube 5.
  • the exhaust gases from the burner hereby heat the flame tube 5, from which the heat is transferred to the inner leg 11 of the double annulus 10.
  • water circulates here, which reaches the further annular space 26 from the three-way valve via line 30. From here, the water flows via the connecting line 35 to the deflection point 14 of the double annular space 10, which it leaves at the upper end of the inner leg 11, specifically through the supply line 15. It is pointed out that the pump 17 can also be arranged in the return line 30 .
  • the circulating water thus contributes, on the one hand, to absorb heat from the hot exhaust gases of the burner passing through the flame tube and, on the other hand, to dissipate it via the plate 28, which separates the interior 25 of the storage container 33 from the hollow cylinder space of the further annular space.
  • the three-way valve 18 is switched accordingly by the servomotor 19.
  • the pump then conveys heated flow water from line 15 into the flow line 31 to the radiators (not shown), from which the water is returned via the return line 32 to the outer leg 12 of the double annulus 10, namely at its upper end on the cover side.
  • This cool return water flows through both legs of the double annulus and leaves the water reservoir through the feed line 15.
  • This circuit does not heat the process water.
  • the insulation 38 largely protects the water stored in the interior 25 of the water storage container 33 against the cool fresh air which passes through the third annular space 27. It would be possible to carry out the insulation over the entire height of the housing 1 on the sheet metal 28, which shields the third annular space 27 from the outside from the further annular space 26, so that the medium flowing into the further annular space 26 from the fresh supply air supplied does not flow during process water heating is cooled. The same insulation could also be carried out on the outside of the plate 28. that limits the outer leg 12 of the double annulus 10.
  • ring plates which can be made of steel or aluminum
  • ceramic tubes can also be used. It is also possible to let the water reservoir work tilted by 90 ° so that the axis of symmetry is not arranged vertically but horizontally and a gas or oil blower burner is provided as the burner.
  • the opening 29 can be closed and a new supply air opening can be arranged in the area of the base cover 3.
  • the air-guiding annular space 27 enables thermal separation of the process water from the water supplying the heating. This has the advantage of keeping the process water at a temperature which differs from the water supplying the heating, in particular a higher temperature.
