Definitions

  • the invention relates to a chamber frame seal of horizontal chamber coking ovens according to the preamble of the first claim.
  • the object of the invention is to provide a permanent gas-tight chamber frame seal.
  • circumferential elastic membrane sealing plate By using a circumferential elastic membrane sealing plate, even with larger thermal expansions and larger deformations of the chamber frame, a constant, complete seal between the chamber frame and the stone protection strip or furnace head masonry is always guaranteed, so that no raw gas emissions occur in the area of the chamber frame and wall protection plates.
  • the circumferential elastic membrane sealing plates which are expediently clamped to the chamber frame or the stone protection strip with a circumferential flat iron, ensure constant pressure on the sealing elements designed as soft seals.
  • the contact at the free end can also be supported by an active contact element.
  • These pressure elements can consist of a circumferential or of elastic tubes divided over the circumference.
  • the pressure elements can also consist of spring-loaded pressure plungers distributed over the circumference, which are arranged in a continuous bore in the chamber frame and whose pressure forces can be easily adjusted from the outside.
  • the cast armor usually consisted of individual panels of approx. 1 m in height distributed over the height, which were riveted to a continuous front elastic steel panel
  • the invention provides for a continuous wall protection panel, preferably made of steel, over the entire chamber height is arranged, which engages with lateral support cams behind counter cams located on the chamber frame and that wall protection plate and chamber frame form a fixed connection in cooperation with external fastening tabs.
  • the permanent sealing according to the invention of the inside of the chamber frame with respect to the stone protective strip or the head masonry, in particular the often problematic sealing of the vertical caulking joint between the chamber frame and the wall protection plates, can be dispensed with.
  • the figures show in cross section part of a half of the furnace head construction which is arranged in front of the heating wall.
  • a thin metallic stone protection strip (8) is arranged in front of the furnace head masonry (14), which is held on the one hand by the chamber frame (6) and on the other hand by the wall protection plate (3) in front of the furnace head masonry (14).
  • the wall protection plate (3) stands vertically at a distance behind the anchor stand (1) and is held by means of spring-loaded pressure plungers (2).
  • the chamber frame (6) is held from the outside by means of fastening tabs (4) known per se on the wall protection plate (3).
  • the chamber frame with counter cams (7) lies on the side support cams of the wall protection plate.
  • the membrane sealing plate (12) On an inner projection of the chamber frame (6) facing the furnace masonry, the membrane sealing plate (12) is screwed ver using flat iron (9) and fastening screws (10) over the entire circumference.
  • the free end of the membrane sealing plate (12) facing the center of the heating wall is bent at the end towards the stone protection strip (8), so that sealing cords (11) can be found between the membrane sealing plate (12) and the stone protection strip (8) as soft sealing elements.
  • an elastic tube which is under tension in the installed state is clamped as an additional contact element (cf. FIG. 1).
  • a pressure tappet (19) pressed by a helical spring (20) against the membrane sealing plate (12) is arranged as the active pressure element instead of the elastic tube (13).
  • This plunger (19) is guided in a bore in the chamber frame (6), the contact pressure being adjustable from the outside.
  • an insulation (18) is also used to reduce the temperature from the hot furnace head masonry to the outside to the wall protection plate.
  • B. made of ceramic material, insulating plates (17) and a ramming compound (16).
  • a mortar joint (15) is located between the stone protection strip (8) and the furnace head masonry (14).
