Definitions

  • a thermal fluid boiler has a heating chamber consist- [52] 0.8. C1. «,.122/367 R, 122/136 C, 122/136 i g of two concentric walls.
  • the inner wall has baffles 122/367 C F221! 23/06 122/136 R, 136 C,
  • outer wall has fins secured to the out- 122/367 367 367 A side surface thereof and an outside jacket surrounds the outer wall.
  • the present invention provides a thermal fluid boiler which is very simple in construction resulting in a much lower price, and which may be placed horizontally thus permitting a very good access to the burner and facilitating the cleaning thereof.
  • the boiler in accordance with the invention, comprises an inner wall and an outer wall concentric with the inner wall.
  • the inner wall has baffles secured thereto in the space between the inner and outer walls but not in contact with the other wall.
  • the outer wall has fins secured to the outside surface thereof to lower the flow of the gas circulating around the outside wall and thus increase the heat thermal exchange.
  • An outside jacket surrounds the outer wall and the fins.
  • FIG. 1 illustrates a longitudinal section through a boiler in accordance with the invention
  • FIG. 2 illustrates a plan view of the outer wall of the heating chamber showing the fins for slowing down the passage of the gas
  • FIG. 3 illustrates a plan view of the inner wall of the heating chamber.
  • the thermal fluid boiler in accordance with the invention is characterized in that it may be placed horizontally.
  • the boiler comprises a heating chamber consisting of an inner wall 1 and an outer wall 2.
  • Baffles 3 are secured to the inner wall 1 between the inner and outer walls and fins 4 are secured to the outside of the outer wall 2.
  • An outside jacket 5 surrounds the outer wall 2 and fins 4.
  • the baffles 3 are secured to the outside surface of the inner wall 1 by welding or any other equivalent ways and take the shape of a continuous helix 6 wound around the inner wall 1, but not in contact with the inner surface of the outer wall 2.
  • the outside wall 2 is provided on its outer surface with the above mentioned fins 4 which extend towards the outside jacket 5 without touching it.
  • main purpose of the fins 4 is to lower the flow of gas between the outer wall 2 and the outside jacket 5.
  • the fins 4 are secured to the outer wall 2, as illustrated in figure 2, along a generatrix 8 forming with the axis 9 of the inner wall 1 an angle of 415 and such fins are sloped with respect to axis 9 by an angle of 15.
  • the above described thermal fluid boiler operates as follows:
  • the fluid flows in from the back of the boiler through inlet 10 and circulates in the space between the inner wall 1 and the outer wall 2.
  • the fluid flows towards the front of the boiler between the baffles 3 which, as mentioned previously, have the shaped of a continuous helix 6.
  • a thermal fluid boiler comprising:
  • a combustion chamber having a longitudinally extending horizontal lateral inner wall and a front and a back end;
  • an elongated baffle plate in said flow chamber said plate having one longitudinal edge secured to the outer surface of said inner wall to extend away from said outer surface and with the other longitudinal edge thereof terminating short of the inner surface of said outer wall, said plate winding around said inner wall from said back to said front end in spaced turns and in an uninterrupted helix;
  • a plurality of spaced fins in said flue gas chamber said fins being fixed to and projecting from the outer surface of said outer wall but terminating short of said external casing to slow down the flow of flue gases
  • said fins being disposed along parallel lines making an acute angle with the longitudinal axis of said outer wall, the fins being also disposed parallel, with respect to one another, at an acute angle to said parallel lines.
