Definitions

  • a protection device of this kind comprising auxiliary fins periodically interrupted in certain vertical intervals, a first part of the bricks refractories, provided with vertical notches extending only over a fraction of their height from the bottom, being hooked on the auxiliary fins, and another part of the bricks, generally in greater number, being provided with vertical notches extending over their entire height, the latter bricks being threaded on the auxiliary fins above the bricks of the first part.
  • the object of the present invention is to provide a device for protecting boiler screens as effective as that which is the subject of the above patent application, but easier to install, more waterproof and avoiding the risks of corrosion. tubes and fins by the fumes from the oven.
  • the device according to the invention is characterized in that a second series of bricks, alternating with those of the first part, has at their upper and lower ends recesses giving them a general dovetail shape, and in that the bricks of the first series have corresponding recesses ensuring the blocking between them in position of the bricks of the second part.
  • the auxiliary fins are connected to the tubes by full penetration welds and have a width and a thickness such that their temperature is very close to that of the tubes themselves.
  • the method of manufacturing such a device according to the invention is characterized in that the tubes are placed parallel in a plane, they are joined together by means of securing fins welded between the adjacent tubes, welded on the tubes, elements of auxiliary attachment fins making an angle between 30 ° and 60 ° with the general plane of the axes of the tubes, of height corresponding to a fraction of the height of a first series of refractory bricks provided with vertical notches corresponding to the auxiliary fins and having recesses s' widening towards the side of the hearth, and at intervals corresponding to at least the height of the bricks of a second series, devoid of vertical notches, and having recesses adjusting with those of the bricks of the first series, in that the surface of the tubes, of the fastening fins and of the auxiliary fins is provided, over the height of a first lower row of bricks of the first series, with a coating of refractory cement, in that it is hung on the auxiliary fins of this first row
  • the bricks 4 and 5 are hung by notches in their lower half 2A, 3A on auxiliary fins 2 and 3 welded to the tube 1 (or 11 and 13 on the tube 14).
  • the brick 4 has an upper recess 8 and the brick 5 a lower recess 7 making it possible to hold the brick 6 in place, provided with corresponding recesses 10 and 9, these three bricks forming a dovetail assembly, and the space remaining between the recesses 7 and 9 on the one hand, 8 and 10 on the other hand being filled with a refractory cement, like that remaining between the refractory bricks and the tubes and fins.
  • Horizontal grooves such as 15 and vertical grooves such as 16 allow the establishment of seals between the bricks, in known manner.
  • Figure 2 shows the bricks in elevation.
  • the bricks of the first series such as 4 and 5 and of the second series such as 6 and 18 are placed in an alternate arrangement, a brick of the second series being above and below two bricks of the first series, and reciprocally.
  • the tubes such as 1 and 14 are placed in a plane and weld together joining fins such as 17, for example using an automatic welding machine with consumable welding wire.
  • Bricks 4 are attached to these auxiliary fins 2.
  • the tubes, the securing fins and the upper recesses 8 of the bricks 4 are then provided with the refractory cement coating.
  • Bricks of the second series are put in place such as 6, 18, which are temporarily held by the support of their lower recesses 9 on the upper recesses 7 of the bricks 4.
  • the tubes, fins are again provided with securing and upper recesses of the bricks 6, 18 with a coating of refractory cement.
  • a row of bricks from the first series 5 is hooked onto the auxiliary fins 3. The operation is again started, step by step upwards, from this row of bricks until the entire protective device for the screen.
