Definitions

  • the invention relates to a device for utilizing the flue gas heat from heating furnaces.
  • the object of the invention is therefore to provide a device in which the temperature at the chimney inlet is reduced and the residual heat available in this case is used in a sensible manner.
  • This object is achieved in that a means is present which delays the flow of smoke from the combustion chamber, where the flue gases are at their highest temperature, to the chimney, so that the flue gases can give off most of the heat to their surroundings beforehand.
  • the device according to the invention can be designed as a separate device or can be integrated in the heating furnace.
  • the agent is preferably formed from serpentine tubes or a single tube that goes from the combustion chamber to the chimney. There are no interruptions along the pipe (s), in particular, the necessary seams are cleanly sealed.
  • a serpentine tube with mainly vertical sections forms a heat exchanger with the ambient air.
  • This heat exchanger can be in the same room as the heater, but also be located in another room.
  • the heat emission and thus the flue gas temperature is greatest at the inlet of the flue gases into the heat exchanger. It is also larger in the sections with rising smoke gases than in those with falling smoke gases.
  • the bends of the pipe are designed so that the flue gases are affected as little as possible in their way from the combustion chamber to the chimney. Cleaning openings must also be provided, in the lower arches. You have to keep in mind that the smoke carries dust and soot, which can settle. Removable plugs are used for this purpose, through which one can penetrate two adjacent sections with cleaning brushes.
  • the serpentine tube can be made very compact. It can be clad like a radiator with perforated decorative panels.
  • the residual heat contained in the flue gases is at least partially evaluated for preheating the fresh air for combustion. This makes it possible not to take the fresh air out of the room in which the heater is installed, but to draw it in outdoors with a pipe. It is then advisable to seal the oven openings (furnace opening, ash pan, stove rings for cookers) with a clean fit and latch, and if necessary with asbestos seals. In this embodiment, the burning process can be effectively controlled or regulated by a simple flap in the fresh air pipe.
  • the heating furnace 5 delivers heat by consuming solid or liquid fuels.
  • the flue gases escape through a pipe 3 at a relatively high temperature and are to be cooled in a heat exchanger R before entering a chimney C.
  • the heat exchanger consists of a serpentine tube 1, which is formed essentially from vertical sections 2 with upper and lower elbows.
  • the lower elbows are provided with a cleaning opening 4, which can be closed with a screw plug 5 via a sealing washer 6 and a thread 7.
  • the plugs are removed periodically if you want to clean the inside of the heat exchanger.
  • Fig. 3 shows the view of a second embodiment.
  • This is a solid fuel kitchen stove; on one side you can see the air inlet 28, which is supplied with fresh air from outside via a pipe 22 provided with a control flap (not shown).
  • the smoke outlet 23 leads to the chimney via a connecting pipe 24 and a manifold provided with cleaning plugs 25.
  • the mostly split hob 26 is placed on the furnace body 27 and carries two or more concentric ring covers, the seats of which should be worked very cleanly.
  • Oven doors 9 and 10 for the fuel supply and ashtray are provided on the front wall, each with an airtight seal, for example made of asbestos, and with stop levers which ensure perfect closure.
  • oven doors 11 and 12 of one or more indirectly heated ovens are also also open doors 11 and 12 of one or more indirectly heated ovens, the walls of which must be airtight in relation to the smoke ducts.
  • the cooker body 27 carries the hotplate 26 and is connected to the outside air by two openings 28 and 23.
  • a partition wall 12 made of sheet metal delimits the combustion chamber 15 and the entire structure is sealed airtight with a floor 13. All walls are protected by a cover made of a thermal insulator 14.
  • the combustion chamber 15 is at the bottom of a cast iron grate 16, with grid spacings of no more than 5 mm delimited against the ash pan 21.
  • the air that is sucked in from the outside passes through the opening 28 and under the grate 16 via a smooth or lamellar tube 20 on the outside.
  • the burned gases enter the space 18 and heat the ovens (not shown here) as well as the air supply tube 20 ; then the burned gases are redirected on a baffle 19 again against the pipe 20 and finally passed into the outlet.
  • the ash falls into the ash box 21, which can be pulled out periodically after the airtight door 10 has been opened.
