Definitions

  • the present invention essentially relates to a process for heating industrial liquids at different temperature levels.
  • liquids are at a high temperature , for example greater than 60 ° C, or at an average temperature, for example less than or equal to 60 ° C, is very often necessary.
  • the object of the present invention is to propose a method and an installation which overcomes the above drawbacks and have a high efficiency, in particular with regard to the heating efficiency and that of bringing the heated liquid to the required temperature.
  • the subject of the invention is a method of heating a first liquid in a tank or the like using a tube or an exchanger connected to a burner and immersed in said tank, characterized in that that a portion of this first liquid or of a second liquid contained in a second tank is heated simultaneously using the combustion gases leaving said tube or exchanger and bubbling through this second liquid to heat it to a temperature lower than that of the first liquid.
  • a liquid transfer is carried out from one tank to the other by overflow or by pumping.
  • the combustion gases leaving said tube or exchanger and bubbling through the liquid in the second tank serve to preheat a third liquid which is passed through a liquid-liquid exchanger immersed in the liquid from the second tank and mixed with the liquid from the first tank.
  • Such a procedure is useful when the third liquid is incompatible, for example chemically, with the fumes or combustion gases which should therefore not be brought into direct contact with said third liquid.
  • the first liquid can, according to the invention, be heated in the first tank to a temperature above 60 ° C., while the second liquid is heated in the second tank to a temperature below or equal to 60 ° vs.
  • the invention also relates to a heating installation for implementing the above process, and of the type comprising a tank or the like containing a first liquid heated by an exchanger or tube immersed in this liquid and connected to the outlet of a burner, characterized in that the outlet of said tube or exchanger is connected to a means for diffusing hot gases leaving the exchanger, which means is immersed in a portion of the first liquid or in a second liquid contained in a second tank associated with the first.
  • the first and the second tank form a single tank separated by a partition or the like.
  • At least one pump is provided, fitted with an inlet and outlet pipe plunging into the two tanks respectively.
  • a second exchanger is immersed in the second liquid of the second tank and comprises a liquid supply pipe as well as a pipe for the outlet of this liquid opening into the first tank.
  • This second exchanger is preferably arranged above the means for diffusing the hot gases leaving the exchanger or tube immersed in the liquid of the first tank.
  • an installation in accordance with the principles of the invention essentially comprises two tanks 1 and 2, and immersed and connected heating means for heating respectively to different temperatures the liquids L 1 and L 2 contained in the tanks 1 and 2 respectively.
  • These tanks 1 and 2 can be constituted by two tanks separated from each other or else directly adjacent, or else formed from a single tank separated by a partition shown diagrammatically in 3.
  • This exchanger 5, which can be a simple submerged tube, is connected by a portion of pipe 7 to a diffuser system shown diagrammatically at 8 and immersed in the liquid L 2 of the second tank 2.
  • a pump P provided with an inlet and outlet pipe 9 and 10 plunging into the tanks 1 and 2 allows the transfer of the liquid from one tank to the other.
  • This liquid transfer can be carried out without a pump, that is to say simply by overflowing the liquid from one tank into the other.
  • the combustion products from the burner 4 pass through the exchanger 5 and by heat exchange with the liquid L 1 , the latter is heated to a temperature level above 60 ° C. for example.
  • the fumes leaving at 7 from the exchanger 5 are diffused by bubbling into the tank 2 where the liquid L 2 is heated to a temperature level less than or equal to 60 ° C. for example.
  • the overall heating efficiency of the assembly is conditioned by the reference temperature of the tank 2.
  • the yield varies from 110 to 96% on the lower calorific value for temperatures ranging from 20 ° C. to 60 ° C. in the tank 2.
  • FIG. 2 makes it possible, for example, to heat the liquid L 1 in the tank 1, to produce, for example, hot water at a temperature above 60 ° C., and this with heating yields greater than 100%. on lower calorific value.
  • the tank 2 is equipped with an exchanger 14 immersed in the liquid L 2 and comprising a pipe 15 for supplying liquid and an outlet pipe 16 opening into the first tank 1.
  • an exchanger 14 immersed in the liquid L 2 and comprising a pipe 15 for supplying liquid and an outlet pipe 16 opening into the first tank 1.
  • the dimensioning of the exchanger 5 must be such that the fraction of energy remaining to be transmitted in the tank 2 is small so as to allow an equilibrium temperature to be obtained in this tank much lower than 60 ° C. The yields thus obtained exceed 100% on lower calorific value.
