Definitions

  • the present invention refers to a heating boiler of the type provided with a fluid to be circulated through a conduit system associated to a closed circuit heating installation.
  • the heating boiler defined by the present invention is characterized by working under conditions which increase its caloric capacity and as a consequence increase the total efficiency of the installation.
  • the thermal insulation has been designed in a manner that it totally includes the portion to which the supplied thermal energy is applied at the portion of transfer of said energy to the thermal fluid which circulates through the installation circuit, and in an important part of the associated elements.
  • the rest of the installation is also provided with a suitable thermal insulation in order to reduce the thermal losses in the conduits, the connecting elements and the couplings of the circulation pump and fittings to a minimum in order to obtain a maximum efficiency.
  • the supply is effected by any kind of thermal energy, said input energy being directly used for heating of the mass of a thermal fluid which occupies the interior of a thermically insulated reservoir, and in which interior a circulation zone in form of a double cone is provided.
  • a thermal fluid which occupies the interior of a thermically insulated reservoir, and in which interior a circulation zone in form of a double cone is provided.
  • From the upper portion of the vessel extends the conduit which is directed to the closed circuit in order that the heating fluid circulates with the aid of a driving pump, creating a system operating as a unit, such as a heating installation.
  • a zero-gravity state in utilization of which the fluid to be heated expands, and in the upper portion of the vessel an outlet valve permitting to vent the air eventually present in the mass of the fluid to be processed at the introduction thereof into the vessel is provided as well.
  • the operation of the boiler and of the installation performs in a zero-gravity state in the conduit from which - exactly speak­ing, by effect of the fluid circulation - originates a resulting vacuum in the conduits which converts into a considerable increase of the caloric energy, improves the heat transmission conditions, reduces the flow resistance of the fluid circulating through the conduits and importantly reduces noise emanating from said circul­ation.
  • the elements designated by numerals correspond to the following indicated parts.
  • the vessel 1 in form of a cylindric container of resistant metal sheet and vertically arranged is occupied by a mass 2 of a thermal fluid of suitable density, fluidity, boiling point and other characteristics.
  • an electric resistance element 3 (or a heat applicator of other kind) is situated for heating the mass 2 of the fluid.
  • connection piece 4 forms the entrance for returning the fluid after its circulation through the closed circuit.
  • a one-way valve 5 is pro­vided, the object of which is to permit venting of air eventually introduced into the interior of the body l, establishing a dis­charge of same which assures practically a vacuum condition within the vessel 1 not occupied by the thermal fluid. That is to say, it results therefrom that in the portions in each moment not occupied by the fluid, not only no air is existent but also a vacuum effect is obtained which contributes to the improved heat transfer.
  • the conduit 6 receives the warm water entering through the orifices 7 and circulating towards the conduit 8 suitably thermally insulated at its outside and comprising a circulation pump 9.
  • the connection piece 10 is coupled to the closed circuit.
  • the container 11 is an expansion vessel used to even out the fluid circulation.
  • the vessel 1 comprises in its lower portion a serpentine pipe 12 the ends of which are respectively associated to valves 13 and 14, whereas in the upper portion another serpent­ine pipe 15 is located the ends of which comprise valves 16 and 17.
  • the serpentine pipes 12 and 15 serve to establish minimum temperature differences acting as probes for actuating the valves 13, 14, 16 and 17.
  • valves 16 and 17 When being at a higher temperature than the fluid of the boiler, the valves 16 and 17 open in the same manner as conventional safety valves do and, in turn, to eject the warmer fluid towards the tubing, the valves 13 and 14 open simultaneously to fill with fluid.
  • the valves 16 and 17 are actuated by expansion, as con­verted to pressure, and the valves 13 and 14, inversely connected, are actuated by vacuum.
  • a valve is mounted inversely with respect to the other.
  • baffles or deflector elements of conical shape for the thermal fluid are provided, designated by numerals 18 and 19 and mounted with their vertices opposing each other, defining there a restricted central zone 20 which determines, according to the venturi principle, an increase of the circulation velocity of the heated fluid circulating vertically in the upward direction.
  • Said conical elements are supported within the body 1 by a plurality of rods 21 extending from the portion where the lower and upper conical elements are joined with each other.
  • the conical elements 18 and 19 are closed at their bases.
  • said bases are penetrated by said lower and upper serpentine pipes 12 and 15, respectively, enabling a flow of fluid into and out of the interior of said conical elements 18 and 19 upon opening of the aforementioned valves.
  • the position of the valve 14 enabling an input flow into the lower conical element 18 is as depicted in the drawing or at a similar suitable location in order that a temperature difference between the interior of conical element 18 and the zone where said valve 14 as situated develops upon supply of heat by heater 3.
  • Said conical elements serve to even out the circulation of the thermal fluid and to obtain a homogenization between the different portions thereof, in order that the temperature differences between the fluid returning from the lower connection piece 4 and the fluid leaving by the upper conduit 7 affect the uniformity to a miminum.
