Definitions

  • the invention relates to a space heating device and a method for operating a space heating device.
  • Such space heating devices form radiant heating systems, by means of which rooms in buildings can be heated.
  • Known space heating devices have a pressure and mixing chamber housing with a burner and a fan.
  • a radiation pipe is connected to this unit to form a heat channel.
  • a connection pipe for a flow and a connection pipe for a return are provided on the pressure and mixing chamber housing.
  • a heat flow generated by the burner is fed into the radiation pipe via the connection pipe for the flow.
  • the return flow in the radiation pipe is fed back to the pressure and mixing chamber housing via the connection pipe for the return, creating a closed circuit.
  • a generic space heating device is from the EP 0 503 489 A2 known.
  • This space heating device comprises a radiation pipe connected to a pressure and mixing chamber housing of a pipe system arranged above the room to be heated, the radiation pipe being connected on the one hand to a backflow chamber with a fan and on the other hand to a mixing chamber with a flame tube surrounding a burner.
  • the pressure and mixing chamber housing is designed in a double-screw shape, with two cylinder-like parts forming the housing and a front and back plate having the double-screw shape, while the connecting pipes for the radiation tube are connected to the back plate.
  • the vortex zone in the pressure and mixing chamber housing is designed in such a way that a hot core zone in the area of the burner is surrounded by a cooler air layer of the returning gas, which ensures that heat is released uniformly in the radiant tube over a large distance becomes.
  • the invention is based on the object of providing a room heating device with extended functionality.
  • the invention relates to a space heating device with a radiant tube connected to a pressure and mixing chamber housing.
  • the radiant tube is connected on the one hand to a return flow chamber with a fan and on the other hand to a mixing chamber with at least one flame tube and an associated burner arrangement.
  • the burner arrangement has two burners operated with different fuel media. Switching means are also provided by means of which only one of the burners is selectively activated.
  • the invention also relates to a corresponding method.
  • the basic idea of the invention is to provide a burner arrangement for the space heating device with two burners that are operated with different fuel media. With the switching means, only one burner is advantageously activated at a time and used for operating the space heating device.
  • both burners can be activated by means of the switching devices.
  • the two activated burners are operated at a low power level.
  • the burner arrangement forms a diverse redundant system that increases the flexibility and availability of the space heating system.
  • the switching means activates the burner for which fuel media is available. If, for example, a fuel medium is not available for a burner due to supply bottlenecks or the like, the switching means activates the other burner whose fuel media is available, so that undesirable downtimes of the space heating device are avoided.
  • the burner arrangement comprises a gas burner and a heating oil burner.
  • the burners are operated with common fuel media, achieving high heating outputs.
  • the switching means can be formed by relays, semiconductor switches and the like.
  • a manual burner changeover can be carried out by a user who uses an appropriate actuating device.
  • An automatic burner changeover takes place automatically, in particular program-controlled.
  • the burners are advantageously controlled with a control unit.
  • the control unit can have adjustment means for actuating the switching means.
  • the control unit can have a control panel or similar as a setting device.
  • the user can change the burner setting by making entries on the control panel.
  • a sequence program is implemented in the control unit, by means of which a burner changeover is carried out automatically.
  • control variables, sensor signals and the like can be evaluated, which provide information about the availability of the fuel media, in which case the burner switchover can then be carried out automatically depending on this information.
  • the space heating device forms a heat band in such a way that a radiation pipe with a flow and return is connected to the pressure and mixing chamber housing, whereby a closed circuit is obtained.
  • a warm air stream heated by the burner arrangement is fed into the radiant pipe via the flow, guided in this and fed back to the pressure and mixing chamber housing via the return.
  • the fan of the pressure and mixing chamber housing ensures air circulation between the flow and return and at the same time stabilizes the flame of the burner arrangement.
  • the pressure inside the radiant tube is advantageously lower than atmospheric pressure; a higher pressure only exists inside the pressure and mixing chamber housing, advantageously in the area of a chimney through which pollutants are discharged to the outside in a controlled manner.
  • the space heating device designed in this way forms a self-regulating system, in which in particular the uncontrolled escape of flue gases is avoided.
  • the pressure and mixing chamber housing is designed in the form of a triple screw with three screw segments.
  • the fan is assigned to a first screw segment.
  • a first burner is assigned to a second screw segment and a second burner is assigned to a third screw segment.
  • the pressure and mixing chamber housing is designed in the form of a double screw with two screw segments.
  • the fan is assigned to a first screw segment
  • the burners are assigned to a second screw segment
  • a second burner is assigned to a third screw segment.
  • the fan and the burners are expediently mounted in openings in a rear wall of the pressure and mixing chamber housing facing away from the radiation tube.
  • a regulating flap is present, by means of which an air flow generated by the fan is divided between the second and third screw segments with the burners.
  • the air flow to the two screw segments with the burners can be optimized.
  • the room heating device is operated with an adjustment of the control flap in such a way that it is suitable for operation with each of the burners.
  • control flap is carried out before commissioning.
  • the regulating flap is adjusted manually or using a servomotor so that optimized air flow conditions are achieved regardless of which burner is currently activated.
  • the Figures 1 and 2 show an embodiment of the space heating device 1 according to the invention.
  • the space heating device 1 is mounted beneath a roof 2 of a building 3, in particular a hall.
  • the components of the space heating device 1 are suspended from fastening means 4 which are secured to the roof 2 of the building 3.
  • the space heating device 1 is used to heat the interior 5 of the building 3.
  • the space heating device 1 comprises a radiation pipe 6 which is connected to a pressure and mixing chamber housing 9 with both a flow 7 and a return 8.
  • a burner arrangement 10 and a fan 11 are located on the pressure and mixing chamber housing 9.
  • the burner arrangement 10 generates a flame which heats an air flow fed into the flow 7 of the radiation tube 6.
  • the air flow passes through the radiation tube 6 and is fed back to the pressure and mixing chamber housing 9 via the return line 8.
  • the air flow in the radiation pipe 6 generates thermal radiation, which heats up the interior 5 of the building 3.
  • Figure 2 shows the spatial distribution 12 of the thermal radiation.
  • FIGS. 3 to 5 show the pressure and mixing chamber housing 9, on the front wall of which a connection pipe 13a for the flow line 7 of the radiation pipe 6 and a connecting pipe 13b for the return 8 of the radiation pipe 6 opens out.
  • the radiation pipe 6 is connected to these connecting pipes 13a, 13b.
  • the pressure and mixing chamber housing 9 of the space heating device 1 has the shape of a triple screw with three cylindrical screw segments 14a, 14b, 14c.
  • the fan 11 is assigned to a first screw segment 14a ( Figure 5 ), For connecting the fan 11 to the rear wall 15 of the pressure and mixing chamber housing 9 facing away from the radiation tube 6, an opening 16 is present.
  • the burner arrangement 10 comprises two burners 17a, 17b, wherein a first burner 17a is assigned to the second screw segment 14b and a second burner 17b is assigned to the third screw segment 14c.
  • the first burner 17a is a gas burner and the second burner 17b is a heating oil burner.
  • the two burners 17a, 17b are also mounted in the rear wall 15 of the pressure and mixing chamber housing 9.
  • the outlet of each burner 17a, 17b is led to a flame tube 18a, 18b.
  • the flame tubes 18a, 18b are directed towards the connecting tube 13a, 13b of the flow 7, and thus also a flame generated with the corresponding burner 17a, 17b.
  • a heated air flow is thus generated with the flame of each burner 17a, 17b, which is introduced into the flow 7 of the radiation tube 6.
  • the fan 11 ensures air circulation between the flow 7 and return 8.
  • the air flow generated by the fan 11 is divided by means of a regulating flap 19 so that a partial air flow is supplied to the first burner 17a and a partial air flow to the second burner 17b.
  • the air flow and the partial air flows are in Figure 5 marked with arrows.
  • only one burner 17a, 17b of the burner arrangement 10 is selectively activated via switching means 20.
  • a corresponding diagram of such an arrangement is in Figure 6 shown.
  • control of the switching means 20 for burner tuning is carried out by means of a control unit 21, which advantageously also serves for process control of the room heating device 1.
  • the control unit 21 comprises, in a known manner, a processor unit 22 and an input/output unit 23 with a display or the like.
  • Electrical or electronic switching means 20 such as relays, semiconductor switches and the like can be provided as switching means 20.
  • manual or automatic burner changeover can be carried out by actuating the switching means 20.
  • a user can perform a manual burner changeover by entering data at the input/output unit 23 of the control unit 21.
  • a sequence program is implemented in the control unit 21, by means of which a burner changeover is carried out automatically.
  • the space heating device 1 is operated solely with the gas burner or with the heating oil burner.
  • the regulating flap 19 is adjusted so that the partial air flows generated thereby are suitable for operating the space heating device 1 with the gas burner or with the heating oil burner.
  • the switching means 20 are advantageously actuated depending on the availability of the fuel media for the burners 17a, 17b.
