Definitions
- the present invention relates to a device for protecting screens of heat recovery boilers, in particular for waste incineration ovens, these screens being formed from vertical tubes joined by welded securing fins, disposed behind refractory bricks and being provided with means for hanging refractory bricks. It also extends to a method of manufacturing this device.
- the object of the present invention is to provide a device for protecting the screens of such boilers which is not exposed to progressive destruction by oxidation of poorly cooled metal parts, and which therefore has good longevity, but which is however simple structure and easy to manufacture.
- the device according to the invention is characterized in that the means for hooking the bricks are vertical auxiliary fins making an angle between 30 ° and 60 ° with the plane of the securing fins, in that the auxiliary fins are periodically interrupted on vertical sections of tubes, in that a first part of the refractory bricks is provided with vertical notches of width and thickness corresponding to those of the auxiliary fins, extending only over a fraction of their height from the bottom, and the another part of vertical notches extending over their entire height, and in that the bricks of the first part are hung on the upper part of the auxiliary fins and the bricks of the other part strung on these auxiliary fins above a brick from the first part.
- the auxiliary fins make an angle of about 45 ° with the plane of the securing fins.
- the width of the auxiliary fins is at most equal to half the width of the securing fins separating the tubes, so that these fins are at a low temperature.
- the vertical notches in the first part of the refractory bricks extend over half their height from the bottom.
- the refractory bricks are also secured by vertical refractory cylindrical rods engaging in vertical grooves which they comprise in their external zone, the most distant from the fins for securing the tubes.
- the refractory bricks are joined by horizontal refractory cylindrical rods engaging in horizontal grooves which they comprise in their external zone.
- the manufacturing method according to the invention of such a device is characterized in that a longitudinal fin which is interrupted periodically over a fraction of its height is welded between pairs of tubes, in which the connecting fin is cut each pair of tubes in its middle, thus forming on each tube an auxiliary fin of small width, in that the elementary tubes are arranged parallel in a plane, the auxiliary fins making an angle between 30 ° and 60 ° by relative to this plan and being oriented towards each other, in that we bring together the tubes between them by means of securing fins welded between the adjacent tubes, in that one puts on the upper part of a pair of auxiliary fins a refractory brick provided with vertical notches of corresponding width and thickness to those of the auxiliary fin and extending only over a fraction of their height from the bottom, in that one threads on the pair of auxiliary fins above the first refractory brick at least one other refractory brick provided with vertical notches over its entire height, and in that the operation is repeated over the entire height of the tubes.
- Welding is preferably carried out on the pairs of tubes of the initial longitudinal fin, then the welds between the tubes of securing fins, using an automatic machine with a consumable weld fit.
- the bricks are advantageously secured to one another by engaging refractory vertical cylindrical rods in vertical grooves of the bricks facing each other in their external zone, more distant from the tubes joining fins, and possibly by engaging horizontal cylindrical rods. refractory in horizontal grooves facing the bricks in their external zone, the furthest from the fins for securing the tubes.
- welded fins for example 38 mm wide by 750 mm high, interrupted every 1000 mm over a length of 250 mm, as shown in FIGS. 1 and 2.
- These fins are welded by means of an automatic machine of known type, for example with consumable welding wire, ensuring a very good and constant quality of welding.
- These tubes are placed side by side, divided into groups of two such as 1, 2, 1A, 2A, in which the short fins of two tubes of each group are turned towards each other and make with the plane of the axes tubes with an angle ⁇ of between 30 ° and 60 °, and preferably around 45 °, as shown in FIG. 3, and panels are formed by connecting the tubes together by means of fins 13 welded to the tubes by cords such as 14, 15.
- These welds are also made by means of an automatic machine ensuring a very good and constant quality of weld.
- this fin Being small (width less than diameter external of the tubes), this fin is very well cooled by the fluid circulating in the tube.
- the "type A" bricks shown in FIGS. 4 and 5, have vertical notches 16, 17 of width and depth slightly greater than the thickness and width of the short fins, these notches extending over half lower than their height. They have cylindrical recesses 18, 19 with a radius slightly greater than the radius of the tubes.
- the "type B” bricks shown in fig. 6 and 7, have vertical notches 20, 21 of width and depth slightly greater than the thickness and width of the short fins, like those of the "type A", but extending over their entire height.
- Their cylindrical recesses 22, 23 have a radius corresponding to the radius of the tubes.
- a brick 8 of the "type A” is threaded through the opening located between two short ribs (opening 9 in FIG. 8).
- bricks are supported on the top of the short fins 5A, 5B.
- bricks of "type B” are successively threaded, for example three bricks 10, 11, 12.
- a brick 8A of "type A is threaded through the same opening ", And so on.
- Figure 9 shows in more detail a completed protection element.
- the width 1 of the short fins 3A, 3B arranged in the notches such as 20, 21 of the opposite brick, is preferably close to half that of the fins 13 connecting the adjacent tubes, so that they remain at a low temperature. (below 450 ° C).
- Two adjacent bricks are joined together using vertical rods in refractory material such as 24 threads in the grooves opposite 24A, 24B of the bricks. We can add to them horizontal rods, not shown.
- a refractory cement slurry 25 is injected to ensure the setting between the bricks and between the screen and the bricks and to avoid the passage of smoke along the screen.
