Definitions

  • the invention relates to a boiler according to the embodiment according to claims 1 to 4.
  • a boiler with smooth heating surfaces is known for example from DE 2028253.
  • the annular flue gas is from the smooth inside of a water-cooled cylinder through one to the combustion chamber installation cylinder closed towards the bottom and open towards the exhaust gas outlet filled.
  • the invention has set itself the task of an inexpensive boiler design on the one hand and on the other hand the best possible use of the heat coming from the fuels, with the greatest possible protection of the environment to reach.
  • the solution to this problem is described in claims 1 to 4.
  • the vortex disks cause the exhaust gases in front of and in the spaces, of the vertebral discs, freely distribute and mix to afterwards to flow through a slight resistance to the next gap. While the relatively long time in the interstices the exhaust gases transfer their heat to the heat transfer medium. This is done by the large surface of the fins on the heat transfer side of the combustion chamber and the heat zone wall favors. This makes it a particularly affordable one Heat transfer from the warm exhaust gas to the heat transfer medium instead.
  • the vertebral discs are of suitable devices, preferably in the middle and with little Loss of space, held in the most favorable position in the direction of flow.
  • the vertebral disks For maintenance and cleaning purposes, the vertebral disks, especially if they are combined in packages, easily removed and then again be used in the correct position.
  • the heat exchanger surfaces are at removed vortex discs, on the inside of the combustion chamber wall and the The heat zone wall is clearly visible and can be easily checked easily accessible for cleaning. Anything touched by the exhaust gas condensate Parts are coated and made of mild steel to remove toxic heavy metals to avoid.
  • Fig. 1 shows an embodiment of a boiler in a vertical construction.
  • the burner (1) burns vertically into the combustion chamber (2).
  • the heat recovery zone (3) is arranged below and below this combustion chamber (2).
  • the swirl plates (5) with their gaps (6) ensure good heat transfer to the heat transfer medium (14) via the circumferential ribs (7), which are firmly connected to the combustion chamber wall (13) and the heat recovery zone wall (15) on the heat transfer medium side.
  • the cooled exhaust gases then leave the boiler via the condensate separator (8) and the exhaust pipe (9). Exhaust gas condensate is discharged via the condensate connection (12).
  • the heat transfer fluid enters the heat transfer chamber via the return connection (10) and exits from the supply connection (11) again.
  • the condensate separator (8) is attached to the boiler with the flange (19).
  • a bracket (20) ensures the central and secure support of the spacer (18) of the swirl discs (5).
  • a support (17) causes the spacer (18) to dip into the holder (20) as provided.
  • Adjustable centering brackets (21) in the upper area of the waste heat zone (3) ensure precise centering of the swirl discs (5).
  • At least the first swirl disk (5) after the combustion chamber (2) is provided with insulation (16) over the entire surface in order to dissipate the heat coming from the burner (1) or another device.
  • Fig. 2 shows an embodiment of a boiler in a horizontal design.
  • a burner (1) or another heat source burns in the combustion chamber (2).
  • the waste heat zone (3) connects to this combustion chamber (2).
  • the swirl plates (5) with their gaps (6) ensure good heat transfer to the heat transfer medium (14) via the ribs (7), which are firmly connected to the combustion chamber wall (13) and the waste heat zone wall (15) on the heat transfer medium side.
  • the cooled exhaust gases then leave the boiler via the condensate separator (8) and the exhaust pipe (9). Exhaust gas condensate is discharged via the condensate connection (12).
  • the heat transfer fluid enters the heat transfer chamber via the return connection (10) and exits from the supply connection (11) again.
  • the condensate separator (8) is attached to the boiler with the flange (19).
  • a bracket (20) ensures the central and secure support of the spacer (18) of the swirl discs (5).
  • a support (17) causes the spacer (18) to dip into the holder (20) as provided.
  • Adjustable centering brackets (21) in the front area of the waste heat zone (3) ensure precise centering of the swirl discs (5).
  • At least the first swirl disk (5) after the combustion chamber (2) is provided with insulation (16) over the entire surface in order to dissipate the heat coming from the burner (1) or from another device. With the horizontal design of the waste heat zone (3), the centering brackets (21) prevent the vortex disks (5) from being moved unintentionally and with the help of the brackets (22).
  • FIG. 3 shows an embodiment of a boiler in a horizontal design with separate combustion chamber (2) and heat recovery zone (3).
  • a transfer duct (4) leads the hot gases from the brewing chamber (2) into the indirect heat recovery zone (3).
  • the exhaust gases give off their heat to the heat transfer medium (14) in a known manner, as described.
  • the arrangement of the vertebral discs (5) with the spaces (6) in this construction is identical to the horizontal design described in FIG. 2. In this case, however, the vortex discs (5) are subjected to heat from the transfer duct (4).
  • the waste heat zone (3) is closed at its front end with a door (25). The cooled exhaust gases leave the waste heat zone (3) via the exhaust gas and condensate drain (23).
