Definitions

  • suctioned or blown air burners have a head made of a thin metal sheet, provided with one or more arrays of holes and/or slots from which the fuel gas and combustion air mixture is released and the combustion occurs. These burners come in different shapes and configurations, depending on the particular use the same are intended for.
  • the gas supplier at times provides for the use of various types of natural gas, which could be more or less rich in calories, or coal gas, methane, propane or other fuel gases. At times, for availability reasons, said gases can even be more or less mutually mixed.
  • a special automatic device When dealing with a blown-air burner, a special automatic device provides for the regulation of the amount of air coming from the supply fan.
  • suctioned air burners it is the same burner, automatically in this case too, which provides for regulating the amount of air suctioned by the Venturi pipe, in such a manner to adapt to the type of fuel gas.
  • the objective of the present finding is to provide a multigas burner, of the blown or suctioned air type, capable of operating without any problems at various heat ranges and free of the drawbacks described above.
  • the burner head be made using a corrugated metal sheet, provided with holes and/or slots arranged on the crest of its corrugations.
  • the burner according to the finding has a head made starting from a sheet 1, made of metal material, preferably stainless steel resistant to heat.
  • This sheet for indicative purposes, shall be approximately 0.4-0.6 mm thick.
  • This sheet is made in a corrugated manner, with crests 1' and valleys 1''. The sheet is cut in such a manner that the gaseous mixture outlet holes and/or slots are arranged at the crests 1'.
  • the sheet 1 is subsequently compressed against the two ends, in such a manner to obtain the shape schematically illustrated in fig. 2 .
  • the head is arranged at the top of the burner 2 (see fig. 3 ) and the flame 3 develops at the abovementioned top.
  • the burner head subject of the finding can be of any shape. Shown, for example, are the ones illustrated by figures 6-9 as well as figures 12-14 .
  • the burner head can be shaped as a series of packs 6 of crests and valleys, mutually separated by flat sections 7.
  • holes 8 can be provided for, to reduce heat transfer from the external to the lower part of the burner.
  • the device subject of the finding can be provided with different shapes (for example tubular shaped).
