Description

Kühleinrichtung für die Feuerraumstirnwand von Rostfeuerungen mit mehreren nebeneinanderliegenden Beschickungsvorrichtungen Die Erfindung betrifft eine Kühleinrichtung für die Feuerraumstirnwand von Rostfeuerungen mit mehreren nebeneinanderliegenden Beschickungsvorrichtungen, durch welche der Brennstoff zonenweise dem Rost zugeführt wird. Die bisher bekannt gewordenen Sammelkörper, an welche die in der Feuerraumstirnwand angeordneten Kühlrohre angeschlossen waren, sind, um jederzeit zugänglich zu sein, über dem Kohlentrichter angeordnet. Dadurch ist es nicht möglich, den der Höhe der Trichter entsprechenden unteren Teil der Feuerraumstirnwand, insbesondere die zwischen den Beschickungsöffnungen liegenden Teile derselben mit Kühlrohren auszustatten.Cooling device for the front wall of the grate furnace with several adjacent loading devices The invention relates to a cooling device for the firebox front wall of grate furnaces with several Adjacent charging devices, through which the fuel is zoned is fed to the grate. The previously known collecting body to which the Cooling pipes arranged in the firebox front wall are connected to at any time to be accessible, located above the coal funnel. As a result, it is not possible the lower part of the firebox front wall corresponding to the height of the funnel, in particular the parts lying between the charging openings with cooling tubes equip.

Gemäß der Erfindung sind die an der Innenseite der Feuerraumstirnwand angeordneten Kühlrohre bis vor die zwischen den Beschickungsöffnungen liegenden Wandteile herabgezogen und an ihrem unteren Ende gruppenweise an je eine zwischen den Beschickungsvorrichtungen auf der Außenseite der Feuerraumwand angebrachte Verteilerkammer angeschlossen.According to the invention, they are on the inside of the firebox front wall arranged cooling tubes up in front of the lying between the charging openings Wall parts pulled down and at their lower end in groups of one between distribution chamber attached to the charging devices on the outside of the furnace wall connected.

Auf der Zeichnung ist eine Ausführungsform der Erfindung dargestellt, und zwar zeigt Abb. i einen Längsschnitt durch einen Feuerraum, Abb.2 einen waagerechten Schnitt durch eine Feuerraumvorderw and nach Linie 2-2 der Abb. i, Abb. 3 einen Schnitt nach Linie 3-3 der Abb. i.The drawing shows an embodiment of the invention, namely Fig. i shows a longitudinal section through a furnace, Fig.2 a horizontal one Section through a combustion chamber front wall along line 2-2 in Fig. I, Fig. 3 Section along line 3-3 of Fig. I.

Vor der den Feuerraum io begrenzenden vorderen Wand i i sind die Brennstoffzuführungstrichter 12 angeordnet, welche den Brennstoff dem Feuerraum zonenweise zuführen. Die Vorderwand ii wird durch Wasser führende Rohre 13 gekühlt, die unmittelbar an oder in der Oberfläche des Mauerwerkes liegen. Diese Rohre 13 sind am oberen Ende zweckmäßig mit dem Oberkessel des Dampfkessels 14. oder einem mit demselben in Verbindung stehenden Sammelrohr derart verbunden, daß der gebildete Dampf frei austreten kann. Die unteren Enden sind gruppenweise zu an, der Außenseite der Vorderwand i i liegenden Kammern i geführt, die ein Reinigungsloch 16 besitzen und untereinander durch nicht dargestellte Rohre verbunden sein können. In die Kammern 15 münden auch Rohre 17, die in einer Isolierschicht oder Zone der Vorderwand i i hochgeführt sind, in der die Temperatur niedriger ist als im Feuerraum. Das obere Ende der Rohre ist derart an den Kessel 14 angeschlossen, daß ein Eintritt von Dampf in die Rohre ausgeschlossen ist. Um den Eintritt von Dampf zu verhindern, können entsprechend ausgebildete Schutzvorrichtungen 18 an den oberen Enden der Rohre 17 vorgesehen sein. Anstatt die Rohre 17 an den Wasserraum des Oberkessels anzuschließen, können dieselben an irgendeine ständig Wasser führende Stelle des Kesselsystems angeschlossen sein.In front of the front wall i i delimiting the combustion chamber io are the fuel feed funnels 12 arranged, which feed the fuel to the furnace zone by zone. The front wall ii is cooled by pipes 13 carrying water, which are located directly on or in the surface of the masonry. These tubes 13 are expediently connected to the upper boiler at the upper end of the steam boiler 14. or a collecting pipe connected to the same connected in such a way that the vapor formed can escape freely. The lower ends are guided in groups to chambers i located on the outside of the front wall i i, which have a cleaning hole 16 and each other through tubes, not shown can be connected. Pipes 17, which are in an insulating layer, also open into the chambers 15 or zone of the front wall i i where the temperature is lower than in the firebox. The upper end of the tubes is connected to the boiler 14 in such a way that that entry of steam into the pipes is excluded. To the entry of To prevent steam, appropriately designed protective devices 18 can be attached the upper ends of the tubes 17 may be provided. Instead of the pipes 17 to the water space of the upper boiler, they can be connected to any permanent water supply Point of the boiler system.

.Die unteren Enden der Rohre 13 und 17 sind in die Kammern 15 so eingeführt, daß sie von der Öffnung 16 aus zugänglich sind und von dieser aus eingewalzt und gereinigt werden können.The lower ends of the tubes 13 and 17 are inserted into the chambers 15 so that that they are accessible from the opening 16 and rolled in from this and can be cleaned.

Damit die Reinigungslöcher 16 der Kammern 15 zugänglich bleiben, sind die Brennstofftrichter gemäß Abb.3 so ausgebildet, daß man ständig zwischen denselben hindurch zu den Verschlüssen der Öffnungen 16 gelangen kann.So that the cleaning holes 16 of the chambers 15 remain accessible the fuel funnel according to Fig.3 is designed so that one is constantly between the same can pass through to the closures of the openings 16.
