or the like

The invention relates to alternating holding tubes connected to the boiler circuit right and left curved lower parts to form a roof-shaped support for Ignition vault of boiler furnaces or the like.

Such an arrangement is with a high pressure vessel has become known with a large heating surface, ■ in the case of the evaporator tubes, which are fork-shaped are at right angles to the longitudinal center plane of the boiler and from two lower drums lying next to the grate The side walls of the combustion chamber and the roof of the combustion chamber, ascending towards the upper drums, form branch pipes curved left and right alternately the upper trampling with the left or right lower drum connect and represent a roof-shaped support for the ignition vault.

Against this known, the invention consists in that the support tubes to the formation of diarrhea lanes at the lower, the ignition vault-bearing .Ends arranged with a larger pitch are.

The advantage of the inventive training is that the ignition vault the Space above the grate not completely opposite the boiler room above the ignition vault, in which the holder of the ignition vault

Sch 13455 Ia / 13 a ends and pipe walls forming pipes run, closes, but that lateral diarrhea lanes are formed which, together with the roof-like design of the ignition vault, prevent a deposit of: 5 fly ash, dust and soot, as these slide off the roof-like ignition vault and fall back through the diarrhea alleys onto the grate. The invention is shown in various exemplary embodiments in the drawing, namely Fig. 1 shows a boiler with the installation according to the invention in longitudinal section, Fig. 2 shows the boiler in section along the line H-II according to FIG. 1, FIG. 3 shows the design of the Halter.ungsrohre as fork tubes and Fig. 4 the arrangement of several ignition vaults in high combustion chambers. The furnace 1 of the boiler is lined with the tubular heating surface 2, which consists of the collectors 3 and the distributors 4 and water pipes 5 connecting them to one another. In the exemplary embodiment, a traveling grate 6 is used as the furnace, which is covered with an ignition vault 7 at its .Ausbrandende end. The ignition vault 7 is held by the water pipes 8 which extend from the collector 3 (FIGS. 1 and 2). This mounting of the ignition vault 7 on the water pipes 8 takes place, for. B. by welded to the water pipes 8 pins or tabs. Here it is also possible to attach the ignition vault 7 at a distance from the water pipes 8 by means of correspondingly long holders. The water pipes 8 that are in their! The upper part forms the dividing or steering walls, are bent right and left in their lower part to form a roof-like support for the ignition vault 7 and open into the intermediate chambers 9. The intermediate chambers 9 are arranged at the level of the lower edge of the ignition vault 7 and are connected to the distribution chambers 4 by the pipe sections ι ο. As a result, the throughflow lanes 11 are formed between the intermediate chambers 9 and the distribution chambers 4. The water pipes 8 can be arranged in a wide variety of ways. Thus, the upper part of the water pipes 8 can be guided straight to form partitions or guide walls or can be designed in the manner of a serpentine pipe to accommodate a larger heating surface. Partitions parallel to one another can also be formed, the tubes of which are connected to one another, e.g. B. to form a protective grille for the downstream superheater. 12, are connected by crossing boiler tubes. ; The formation of the throughflow lanes 11 is also possible in that the water pipes 8 are connected to the distribution chambers 4 without the interposition of intermediate chambers and are bent to the right and left with a division corresponding to the desired size of the throughflow lanes. The holding tubes can also be designed as fork tubes, in which case their shaft tubes are connected to the distributors and form the throughflow lanes 11 between them (FIG. 3). In the case of high combustion chambers, the flame path in the combustion chamber 1 can be directed and a good gas turbulence can be achieved by appropriate arrangement of several steering walls consisting of support tubes 8 and ignition vaults 7 assigned to them accordingly (FIG. 4). This arrangement is also suitable for dust firing systems. Pat ε ν ta ν s ρ r 0 c ii ε: 1.
