Definitions

  • the present invention relates to a device for heating enclosed spaces, such as aircraft hangars, theaters, movie theaters, high-rise warehouses, and buildings used for commerce, industry and handicraft, which are usually tall and have large surface areas.
  • Systems are known for this purpose that comprise a closed circuit composed of multiple pipelines which are arranged approximately at the roof or ceiling of the enclosed space; warm air is circulated inside these pipelines.
  • the heating effect is achieved by radiation from the surface of said pipelines towards the floor by suitable insulating reflecting screens.
  • a system of this type is described in Italian patent no. 1,037,880, which includes a burner located directly at the pipeline and a fan for feeding the gaseous heating medium through the pipeline; the fan is located upstream or downstream of the burner.
  • the burner is of the blast type and is inserted at the pipeline, which has the configuration of a closed loop.
  • An aim of the present invention is therefore to solve the described technical problems, eliminating the drawbacks of the described prior art and thus providing a device that allows to heat enclosed spaces by radiation and has high-level safety characteristics for its users.
  • an important object is to provide a device that has very low manufacturing and maintenance costs.
  • Another object is to provide a device that is simple to set up, has a limited number of moving mechanical parts, and allows the use of personnel that is not particularly trained or qualified.
  • Another object is to provide a device for heating enclosed spaces by radiation which has very low installation costs and is reliable and safe in use.
  • the reference numeral 1 generally designates the heating device for enclosed spaces with any surface extension; said device comprises at least one pipeline, designated by the reference numeral 2, which forms a closed circuit that has the desired configuration according to the dimensions of the enclosed space.
  • the device furthermore comprises an atmospheric multiple-flame Venturi-tube or air-stream burner designated by the reference numeral 3.
  • the device is furthermore constituted by a fan, designated by the reference numeral 4, which is interposed at the pipeline 2 in a region that is adjacent to the burner 3 and is preferably contained together with said burner in a suitable containment element 5 that has an appropriate insulation 6.
  • the fan 4 thus draws the burnt gas and sends it into a suitable chamber 7 arranged laterally to the burner 3; downstream of said burner, the combustion gas and the flame, which contains a certain amount of air drawn from outside and of burnt air, mix and allow to obtain a high-temperature gaseous fluid without the aid of heat exchangers.
  • a first gate valve 8 for adjusting the air flow-rate is inserted between the fan 4 and the burner 3.
  • the fan 4 furthermore has a second gate valve 9 for adjusting the discharge of fumes at a suitable discharge duct 10.
  • the discharge duct 10 can furthermore be arranged at the fan 4 or between the fan and the burner 3.
  • the suction inlet 13 of the fan 4 is located approximately at the center of the return duct 14.
  • an air-stream burner 3 is used wherein the air and burnt gas mixture is introduced laterally.
  • Air is fed upstream of the fan 4 by means of a third gate valve 15.
  • the dimensions of the device can be limited in this solution, too, by providing the fan and the burner in a single unit.
  • the invention has achieved the intended aim and objects a device having been provided that allows to heat enclosed spaces by radiation with extremely high user safety characteristics, since the pipeline is at negative pressure and thus does not release into the environment any toxic fumes due to accidental leaks or breakages.
  • the described solution can be used to heat a furnace, for example of the tunnel type.
