Definitions

  • the present invention relates to a pipe assembly for conveying fumes in steel boilers provided with condensate quick evaporating means.
  • the aim of the present invention is to solve the above mentioned problem, so as to reduce the condensate materials and facilitate an evaporation of said condensate materials, during the idle periods in the operation of the burner device associated with the boiler.
  • a main object of the present invention is to provide a fume conveying pipe assembly in which the surfaces contacting the fumes are cooled very slowly so as to facilitate the evaporation of possible condensate materials.
  • Another object of the present invention is to provide such a fume conveying pipe assembly which is very reliable and safe in operation and which can be easily made starting from easily available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
  • a pipe assembly for conveying fumes in steel boilers provided with condensate quick evaporating means said pipe assembly comprises an inner pipe and an outer pipe, which define a closed gap therebetween, characterized in that the outer pipe (3) comprises between said inner pipe and outer pipe parallel contacting lines extending which are made by drawing said outer pipe (3).
  • the fume conveying pipe assembly specifically designed for steel boilers provided with condensate quick evaporating means, according to the present invention, which has been generally indicated at the reference number 1, comprises an inner pipe 2 and an outer pipe 3, coaxial with respect to one another, and so arranged as to define a closed gap 4 therebetween.
  • the inner pipe at the end portions thereof, is enlarged so as to perfectly abut against the outer pipe, thereby said gap 4 is perfectly closed and has substantially an even thickness.
  • the heat conduction between the inner pipe and outer pipe is obtained by contacting lines 10 extending with a helical pattern and which are obtained by a drawing on the outer pipe.
  • the used materials, as well as the contingent size and shapes can be any, depending on requirements and the scope of the claims.
