Definitions

  • the present invention essentially relates to a device for heating industrial liquids in situ.
  • a number of means have already been proposed for heating industrial liquids in situ with combustible gas.
  • the heating can for example be carried out by means of special arrangements provided inside the tank containing the liquid to be heated.
  • special arrangements are fixed, often pose problems of upkeep and maintenance, and generally have a noticeable bulk for most often mediocre yields.
  • boilers comprising a combustion chamber surrounded by a jacket and traversed by water circulation tubes opening into said jacket.
  • the tubes of the boiler in question are arranged obliquely and this is a conventional boiler for central heating of dwellings.
  • a device for heating any liquid of the type comprising a sealed box forming a heating unit immersible in the liquid to be heated and comprising side walls, a bottom wall and a top wall which form at least in part a combustion chamber with which is associated a burner, characterized by one or more channels passing tightly through and through the combustion chamber between said bottom and top walls, and opening at their upper ends and low in the liquid to be heated to allow an upward circulation by thermosyphon of this liquid.
  • grids are arranged around the channels passing through the box to create jets of hot gas around them.
  • the combustion chamber is associated with a premange and homo chamber.
  • fuel generation which contains one or more distribution grids of this fuel before combustion.
  • a heating device essentially comprises a compact heating assembly 1 which is in the form of a box 2, preferably parallelepipedal, and entirely submerged in the liquid to be heated 3.
  • This liquid can for example be an industrial liquid contained in a tank (not shown). We have only shown at 4 the level of this liquid 3 in FIG. 2.
  • the heating unit or box 2 has six walls forming as many exchange surfaces and one of which 2a is provided with pipes opening above the level 4 of liquid 3, as can be seen in FIG. 2. More precisely , the supply of fuel-oxidant air gas, in a substantially stoichiometric quantity, takes place via a pipe 5 opening into a chamber 6 for premixing and homogenizing the fuel, as can be seen better in FIGS. 2 and 3. Another pipe 7 visible in FIG. 1 allows the passage of the electrical ignition and safety connections of the burner. Finally, the cold burnt gases are discharged through a third pipe 8 which opens into the combustion chamber 9.
  • channels 10 can have any shape in cross section, for example circular or polygonal, as can be seen in Figure 3. They allow the circulation, by thermosiphon, of the surrounding liquid 3 as is material. read by arrows in FIG. 2.
  • vertical channels 10 advantageously increase the external exchange surface formed by the walls of the box 2.
  • the exchange surface in question can be further increased by providing metal fins or the like 11 around the channels 10, as shown for example in FIG. 6.
  • the part of the box 2 containing the flame and forming combustion chamber 9 preferably comprises means creating turbulence of hot gas inside this chamber to give the heating unit 1 good performance with a minimum of space.
  • These means can be arbitrary and arranged in any way in the combustion chamber 9. Thus they can for example be constituted by grids 12 arranged around the channels 10, as seen in FIG. 5. Consequently, the grids 12 will favor the formation of jets of hot gas directed towards the exchange walls produced by the channels 10.
  • the premix chamber 6 advantageously contains one or more grids 13 suitably arranged inside thereof so as to achieve an ideal distribution of the gaseous mixture arriving via line 5.
  • This grid 14 which is seen on a larger scale in FIG. 4 is preferably consisting of a metal plate pierced with one or more networks of holes 15, which plate is formed of several sheets, sheets, metallic fabrics, or the like 16 superimposed, assembled, and themselves pierced with holes, as for example described in French Patent No. 2,063,803 belonging to the plaintiff.
  • Such a grid 14 advantageously makes it possible to obtain a high combustion intensity which can lead to heating powers of up to 2 kW / cm 2 .
  • a gas burner with high combustion intensity has therefore been produced according to the invention and associated with a combustion chamber so as to form a very compact, removable, versatile heating unit which can very easily be immersed in a tank containing a liquid to heat whatever, using a winch for example.
  • the heating block according to the invention makes it possible to reach a heating power ranging from 1,000 to 2,000 kW / m 3 occupied, and that the yields obtained with this block are approximately 20% higher than those liquid heating systems used to date.
  • the means 12 creating turbulence in the combustion chamber 9 can have any structure and arrangement inside thereof, the number and structure of the distribution grids in the premix chamber 6 can also be any number, and any number and shape can also be provided for the vertical channels 10 in the combustion chamber formed inside the metal box 2. Likewise, this box can have a shape other than parallelepiped.
