Definitions

  • the invention relates to a method with which the heat recovery from chimneys, in particular from chemical plants, is made possible. This also includes a device for carrying out the method.
  • Various methods and devices are known today with which the heat generated especially in fireplace fires can be better utilized.
  • Various types of heat exchanger systems are usually heated directly by the flames.
  • the heat exchanger systems known to date have the following disadvantages: 1. the efficiency is relatively small, 2. systems with good efficiency are very expensive in terms of space and money.
  • the invention is based on the task of recovering the energy lost by the chimney with an efficiency of approximately 100% with minimal design effort. This is achieved according to the invention in that the smoke-carrying duct of the chimney is brought into direct contact with a second duct running in parallel. Air is blown through this second channel in the direction opposite the smoke flow, which air sc rauc u ren en ana mmer me r warm. Air heated in the counterflow principle is fed to the system to be heated.
  • FIG. 1 shows a schematic cross section. Hot gases are generated in fire 1, which rise through chimney 2 and are conducted outside at 3. Cold fresh air is drawn in by the blower 4 and is conveyed through the duct 5 from top to bottom to the outlet opening 6. In the chimney 2 there is a warm gradient from the fire 1 to the outlet opening of the chimney 3 in that there are very high temperatures near the fire and lower temperatures at the outlet opening 3. In accordance with this gradient, the air which is blown from top to bottom through channel 5 is heated and extracts so much heat from the rising gases that ideally the smoke emerging at 3 has an outside temperature. The heat is controlled by switching the fan on and off. When the blower is switched off, the channel 5 can warm up again enough that previously condensed smoke components evaporate again.
  • FIG. 1 The principle shown in FIG. 1 can already be implemented during the construction of the chimney by suitable construction of the chimney elements to be stacked on top of one another. From Figure 2.
  • FIG. 2a shows a schematic cross section at the position of the element in FIG. 2b marked X-X.
  • Figure 2b shows the supervision of such an element.
  • the hot smoke rises in channel 1.
  • duct 3 the air to be heated is blown from top to bottom.
  • Cross connections 2 in a vertical or spiral arrangement between the channel walls la and 3a stabilize the channel 1 within the channel 3.
  • insulation material is referred to, which firmly connects the channel wall 3a with the outer wall of the element 5.
  • the surface and heat transfer can be increased by suitable shaping by using a particularly heat-conducting material (for example steel) in the construction of the wall la and the cross connections 2.
  • a suitable shaping of the upper and lower end edges of the channel 1 By means of a suitable shaping of the upper and lower end edges of the channel 1, a gas-tight connection between the individual elements can be achieved. Laying such elements on top of each other results in a chimney with a built-in heat exchanger.

Abstract

Procede et dispositif pour la mise en oeuvre du procede permettant la recuperation de la chaleur, dans les cheminees et notamment dans les cheminees d'appartement. On atteint ce but, en amenant l'air a rechauffer - separe uniquement par une paroi (5) conductrice de la chaleur du canal (2) d'amenee de la fumee - antiparallelement a ce canal au local a rechauffer. Le procede peut etre realise par montage apres coup dans une cheminee existante ou par une construction particuliere des elements utilises lors de l'amenagement de telles cheminees.
