Definitions

  • the invention relates to a refractory plate-shaped molded block for lining a combustion chamber, wherein the molded block covers mutually parallel, heat-dissipating tubes and back vertical teilzylindharilindharilogical longitudinal recesses, in each case a pipe partially extends such that there is a distance between the tube outer wall and the wall of the longitudinal recess which is fillable by a mortar or concrete, and wherein the shaped brick has at least one vertical, inwardly widening groove to receive the head of at least one retaining pin which is fixed to a pipe or to a web of the pipes.
  • the object of the invention is to improve a plate-shaped molded block of the type mentioned above, that with a simple construction and easy handling an exact attachment is achieved, with a secure support is given, which keeps the shaped brick invariable in height and a stretching movement of the molded block in the vertical direction.
  • the groove ends in front of the upper edge of the molded block.
  • the groove may end before the upper third or fourth of the molded block.
  • At least one spacer project in the base of the vertical longitudinal recess. It is particularly advantageous in this case if the spacer is strip-shaped and runs parallel over the particular entire length of the longitudinal recess. These strip-shaped spacers are located at the apex line of the respective tube and thus ensure a secure parallel position of the molded block relative to the tubes.
  • At least the rear side is coated with a water-repellent material. It is also advantageous if the narrow sides are circumferentially provided with a fiber strip, so that movements and expansions of the molded blocks are mutually possible. It is also particularly advantageous if the front side facing the combustion chamber has a coating which repels slag.
  • a simple, secure and close fitting of the stones is made possible when the upper and lower narrow side of the block are inclined and designed so that their longitudinal edges are perpendicular to the tube axes. For this purpose, it is also proposed that the lateral narrow sides of the shaped block are inclined and designed so that their longitudinal edges are parallel to the tubes.
  • a lining of a combustion chamber with vertical heat dissipating pipes which are covered by bricks according to one of the preceding claims, wherein on the pipes, in particular fastened between the pipes webs, retaining pins are mounted substantially horizontally protruding, attached to the free end of a head
  • the shaped brick having at least one vertical, inwardly flared groove to accommodate the head of a retaining pin which is attached to a pipe or to a web of the tubes, it is advantageous if the head on the pipes facing side has a conical surface, which comes to two corresponding oblique undercuts of the groove to the plant.
  • one of the oblique undercuts can be arranged closer to the head, as the other undercut. It is also advantageous if the head when pushing the block with its groove on the head, the head through one-sided contact on a Nutenodorwand in particular on a slope on the thread of the retaining pin is rotatably adjustable.
  • the plate-shaped molded block 1 of ceramic material in particular of silicon carbide, has a front side 2, which faces the firebox and thus forms the firebox interior wall.
  • the vertical narrow sides 3 are step-shaped and there are fiber strips 4 of refractory material inserted to seal the blocks against each other to absorb material strains and prevent them from rubbing against each other.
  • the back 5 of the molded block 1 forms two vertical, parallel to each other teilzylindharide L jossaus principle 6 whose cylinder axis is parallel and close to the longitudinal axes of the vertical tubes 7, which are covered by the molded bricks 1.
  • the tubes 7 are traversed by a heat-dissipating coolant and connected to each other by webs 8, which are welded centrally on the outer sides of the tubes and extend parallel to the molded blocks.
  • this distance or space 9 after attaching the Form stones 1 are filled by a mortar or concrete.
  • 6 strip-shaped spacers 10 are formed on the bottom of the longitudinal recesses as sliding strips on the longitudinal recess 6, which extend over the entire length and thus over the entire height of the molded block 1, and thus an upward relative movement between the plate and mortar / Allow pipe wall.
  • these spacers are semicircular in cross section.
  • a vertical groove 11 is introduced into the back of the block 1, which opens to the back 5 and extends from the lower end of the block to at least the middle and preferably slightly beyond, so that the groove in front of the upper edge of the shaped block terminates in particular before the upper third or the upper quarter of the shaped block.
  • the groove 11 Seen from the molded block back side, the groove 11 widens inwards, so that the groove 11 has undercuts 12 on both longitudinal sides in the form of inclined surfaces 13.
  • the head 14 of a bolt-shaped retaining pin 15 is located, wherein the head has a conical surface 16 which comes to the inclined surfaces 13 to the plant when the molded block 1 is pushed over the retaining pin 15 with the head 14 from above.
  • the retaining pin 15 is fixed to the web 18 in particular welded or screwed and has at its free end an external thread 17 on which the head 14 is screwed with a threaded bore. If the molded block 1 is pushed from above, then it can be ensured that the inclined surface 13 rubbing on one side of the head comes into contact and thus the head 14 loftver Jr to achieve an exact distance of the molded block 1 relative to the tubes 7. The Drehverstellen is facilitated when one of the oblique undercuts 12 is arranged closer to the head 14, as the other undercut.
  • the groove 11 opens into a lower recess 18, which forms an equally wide extension to both sides of the groove 11 and thus upper horizontal contact surfaces 19.
  • This downwardly open Recess 19 is filled during filling of the distance 9 and the groove 11 at the same time, so that the mortar or concrete material in the recess 19 after hardening forms a base on which the molded block 1 rests safely.
  • the back side 5 of the molded block 1 is coated with a water-repellent material and the combustion chamber facing the front 2 may have a slag-repellent coating.
  • the narrow sides 3, 20, 21 are not arranged at the top, bottom and sides at right angles to the front and back of the block, but at an oblique angle of 30 to 60 degrees.
  • the lateral longitudinal edges 20a, 20b, 21a, 21b of the upper lower narrow sides 20, 21 perpendicular to the axes of the tubes 7 and the lateral longitudinal edges 3a, 3b of the lateral narrow sides 3 parallel to the axes of the tubes. 7
