Definitions

  • the present invention essentially relates to an installation 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.
  • heating methods and installations comprising a tank containing a liquid heated by an exchanger or tube immersed in this liquid and connected to the outlet of a burner, and in which the outlet of the exchanger or tube is connected to a second enclosure containing a second liquid heated by bubbling the hot gases leaving the exchanger , in this second liquid.
  • the object of the present invention is to propose an installation which overcomes the above drawbacks and has a high efficiency, in particular with regard to the heating efficiency and that of bringing the heated liquids to the required temperature.
  • the subject of the invention is a heating installation comprising a first tank containing a first liquid, a second tank containing a second liquid, a partition separating the first liquid from the second liquid, an exchanger or tube immersed in the liquid of the first tank and connected to the outlet of a burner, this exchanger also being connected to a means for diffusing the hot gases leaving the exchanger, said diffusing means being immersed in the liquid, contained in the second tank, characterized in that the first and second tanks each comprise a supply and withdrawal line for the first liquid and the second liquid which is heated to a temperature lower than that of the first liquid, and in that a pump provided with a supply line inlet and outlet immersed in the two tanks allows the transfer of liquid from one tank to another to make the energy need topping up of the two tanks and thus regulate the temperature of the two x liquids in these tanks.
  • 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 the liquids L, and L respectively to different temperatures. 2 contained in 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 pipe portion 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.
  • the dimensioning of the exchanger 5, the volume of the two tanks 1 and 2, and the quantities of liquid to be transferred are to be optimized as a function of the rise in temperature of the tanks and of the withdrawal methods.
  • An installation was therefore carried out according to the invention allowing the heating of liquids at two different temperature levels with a single heating equipment, the heating efficiency of this installation, based on the lower calorific value, being greater than 100% than that either in the case where it is desired to use a single liquid at a temperature above 60 ° C, or in the case where it is desired to use two liquids at respectively different temperatures, one being greater than 60 ° C and the other less than 60 ° C.
