Definitions

  • the invention relates to a radiant heater for large-scale heating with at least one radiant tube at one end of which a burner device is arranged and at the other end of which a flue gas outlet can be connected to a chimney extractor, the radiant tube in the area of the burner device for shielding against direct flame exposure and overheating, fire-proof insulation and has a large diameter suitable for radiation of long-wave heat radiation.
  • Such radiant heaters are suspended from the ceiling of a room to be heated under a reflector and operated with an atmospheric gas burner device which burns LPG or natural gas.
  • Heaters of this type emit heat in the form of infrared heat radiation and are therefore suitable for use in heating large rooms such as work or sports halls or the like.
  • infrared radiators with exhaust gas temperatures of around 500 ° ; is, however, associated with significant disadvantages in terms of efficiency compared to radiators that work in a medium temperature range while emitting long-wave heat radiation, since the lower exhaust gas temperatures of approximately 200 ° in medium-temperature radiators allow a much better utilization of the heat of combustion.
  • gas-powered radiant heaters also precludes the fact that a gas connection or a gas storage device is not available everywhere.
  • infrared radiators are also associated with disadvantages, since not only the exhaust gas losses are very high, but also that the efficiency of heating the rooms is considerably lower than with long-wave medium-temperature radiation.
  • radiant heaters for large-scale heating with a radiant tube have already been proposed, they have only been used for operation with an atmospheric gas burner.
  • the burner device is provided at one end of the jet pipe, while the suction device which generates a vacuum is arranged at the other end and serves to draw the relatively soft flame of the atmospheric gas burner over the entire length of the jet pipe.
  • the radiant tube is designed with a large diameter suitable for radiating long-wave heat radiation and has a fire-proof insulation in the area of the burner device for shielding against direct flame exposure and overheating (US Pat. No. 4,529,123).
  • FIG. 1 shows a heat radiator with a U-shaped radiation tube 10, at one end of which a burner device 20 and at the other end of which an exhaust pipe 30 which can be connected to a chimney exhaust is arranged and which generates a negative pressure in the radiation tube 10. Due to this negative pressure, the burner flame generated by the burner device 20 and the combustion gas / air mixture which is produced in the process are drawn from the burner side of the jet pipe 10 to the exhaust gas nozzle 30 and sucked out through the latter.
  • the jet pipe 10 is constructed from longitudinal elements 11 and 12 and a connecting piece 13. In the area of the exhaust pipe 30, the end of the radiation tube 10 is closed by a cleaning cover 12c.
  • the burner device 20 which consists of a pressure oil burner 21 and a blower 22, is fastened to a swivel device or a door at the end of the radiation tube 10 on the burner side in order to facilitate an inspection.
  • the radiation tube 10 is provided with an insulation layer 60 over its entire length L, which has an effectiveness that decreases from the burner side of the radiation tube 10.
  • the gradation of the effectiveness can either be selected linearly or is adapted to the decrease in the temperature of the combustion gas-air mixture, whereby the arrangement of the insulation layer 60 makes it possible to achieve a relatively high combustion gas-air mixture in the entire passage area through the radiation tube 10 Has temperature, so that a uniform heating of the radiation tube 10 and thus a uniform radiation is possible.
  • the insulation 50 in the area of the radiation tube on the burner side can be implemented by a pipe socket 150 arranged concentrically in the radiation pipe near the burner device 20, which is connected to the burner device 20, the annular space 151 formed between the radiation pipe 10 and the pipe socket 150 on that of the burner device 20 facing side is closed.
  • An additional insulation layer 152 can be arranged in the annular space 151.
  • a trapezoidal reflector 40 is arranged above the radiator, the inside of which can be mirrored in order to enable better radiation reflection.
  • the refector 40 is preferably provided on its side facing away from the radiator with an additional insulation layer 41, so that insulation takes place towards the ceiling so that almost all of the thermal energy is available for heating the room.
  • the radiation tube 10 which has a diameter D such that there is a boring heat radiation due to the amount of heat available, can additionally in the region of its opposite sides 11 a, 12 a and / or in the region of the downward sides 11 b, 12 b be provided with additional insulations which bring about uniform heat radiation downwards and towards the reflector 40, so that overall a uniform heat radiation is made possible.
  • the heat radiator 100 is suspended on a ceiling 31 at a suitable distance via support strips 42. At one end it is connected with the suction device 30 to a chimney 130, while the burner 20 arranged at the opposite end of the radiation pipe 10 is connected to an oil tank 70 via an oil line 72 which has an oil filter 73 and an oil pump 71.
  • the burner device 20 is controlled in a manner known per se via a room sensor 81 and / or a time control device 80 (FIG. 4).
  • the energy saved 3 is purely qualitative if the temperature curve 1 of a heat radiator, which has a temperature of 15 ° C. at the desired measuring point, for example , is compared with the temperature door curve 2 of an air heater which has a temperature of approximately 18 ° C. at the desired measuring point.
  • the entire design of the heat radiator is designed such that the burner device can be operated in the overpressure range.
  • the radiation tube 10 is made gas-tight over its entire length L, and flow resistances are provided in the radiation tube.
  • a flow resistance designed as an orifice 170 can be arranged in the area of the exhaust port 30. This results in a significant improvement in the overall efficiency.
  • turbolators are arranged in the radiation tube 10.
  • These turbulators designed as baffles or swirling devices, destroy the laminar flow, so that swirling is achieved in the amount of gas flowing through the radiation tube 10 from the burner device 20 such that the hot core gases of the gas jet also act on the inner wall of the radiation tube 10 and the heat emission in relation accelerate to the gas. This results in a significant reduction in the exhaust gas temperatures while maintaining the desired radiation, which significantly improves the efficiency.
