Definitions

  • the invention relates to a channel for discharging the combustion gases of a boiler system of heating or turbine power plants according to the first part of claim 1.
  • the heat exchangers are formed by parallel plates arranged one above the other; To achieve an S-shaped course of the channel, the heat exchangers are also arranged in sections lying one above the other; here, deflecting spaces are provided for the deflection of the combustion gases from one section to the other, the ends of the plates forming the heat exchangers all ending in a vertical plane.
  • Such deflection rooms prevent the duct from being directly connected to buildings or other facilities.
  • swirls can occur in the deflection rooms, which result in an uneven loading of the individual rooms of the heat exchanger.
  • the invention would like to avoid these disadvantages and thus strives for good connection options for the duct and furthermore a more even utilization and utilization of the individual components of the heat exchanger.
  • the channel is essentially enclosed by an approximately cuboid housing 1, which has an inlet 2 for the combustion gases at the top right and an outlet 3 for these gases at the bottom on the left.
  • the housing 1 ensures adequate insulation and can be directly connected to the outer wall of the boiler house on the right side.
  • a fan 4 is required in the area of the outlet 3 to generate an artificial draft, but there is the great advantage that any escaping pollutants can be caught near the ground and cannot be discharged upwards into the open.
  • a plurality of sections a, b, c and d of the channel are arranged closely one above the other, each in a horizontal position.
  • the combustion gases are guided back and forth in the shape of the arrows in the sense of the arrows, with one section flowing through and then the next flowing when the deflection point 5 has passed.
  • Each section a - d is assigned a heat exchanger which consists of hollow plates 6 which are horizontal in the parallel position are arranged. On both sides of each heat exchanger, side plates 7 - also held hollow - are arranged vertically. The plates 6, 7 are connected by elbows 8 so that cold water can flow into the heat exchanger at 9 and warm water can drain off at 10.
  • the heat exchangers of the various sections a - d are in turn connected to one another in terms of pipes; nor is it absolutely necessary that the partition between two adjacent sections be formed by the plate 6 of a heat exchanger. Rather, an insulating plate can also be provided as a separation if necessary.
  • the grading dimensions x, y and z thus correspond to one another, but opposing gradations are provided if a deflection point 5 is considered.
  • the plate 6 located the most outside (at the deflection point 5) delimits the deflection point 5 upwards in the heat exchanger of section a, while the plate 6 lying at the bottom or its end limits the deflection point 5 downwards. This creates a somewhat triangular (equilateral) deflection point 5, the tip of which is directed at the parting plane between adjacent heat exchangers.
  • the grading can be achieved most simply by moving a plurality of plates 6 of equal length; for them it is only a matter of their attachment in the sense of the drawing in the offset state, it being advantageous if there is symmetry.
  • the separating layer (parting plane) between two superimposed heat exchangers formed by a plate 6 of one of the two heat exchangers.
  • the supply of the combustion gases from inlet 2 to inlet 11 in the heat exchanger located above also takes place via a line 12 which is delimited at the top by the housing 1 and at the bottom by the plate 6 of the heat exchanger of section a located at the top.
  • the guidance of the medium to be heated is particularly advantageous if it is carried out in the direction of arrows 13 according to FIG. 2.
  • the medium is introduced into the bottom plate 6 on one side, passed through it, drawn off on the other side and fed to the plate 6 lying above, plates 7 being completely dispensed with and the transfer of the water or medium directly from one Plate 6 can be done to another.
  • This S-shaped guidance of the medium means that the heated medium can be removed at the top in the direction of arrow 10.
