Description

maschinelle Vorfeuerung für Dampfkessel mit Well- oder Siederohren. Maschinelle Feuerungen haben für Flammen-und Feuerrohrkessel vielfach schon versuchsweise Anwendung gefunden, kamen aber zu keiner Verbreitung, sondern wurden abgerissen, weil in Fällen, wo sie als Innenfeuerungen angeordnet waren, es sich herausstellte, daß hinsichtlich Abschlacken die Schwierigkeiten und Störungen unüberwindlich waren und ferner die Unterbringung der für eine gute Dampfleistung erforderlichen Rostflächen, namentlich dann, wenn minderwertige Abfallbrennstoffe in Frage kamen, nicht ermöglicht werden konnte. Waren sie aber als Vorfeuerungen vor den Kesseln angeordnet, ergaben sich zu große Wärmeverluste und derartig schnell fortschreitende Zerstörungen an den die Feuerungen umgebenden feuerfesten Gewölben, daß auch hierbei der Betrieb schnell aufgegeben werden mußte.Mechanical pre-firing for steam boilers with corrugated or boiler tubes. Mechanical furnaces have often been used on a trial basis for flame and fire tube boilers Found application, but did not spread, but were demolished, because in cases where they were arranged as internal firing it turned out that with regard to deslagging the difficulties and disturbances were insurmountable and also the accommodation of the grate surfaces required for a good steam output, in particular when inferior waste fuels came into question, not allowed could be. But if they were arranged as pre-firing in front of the boilers, they yielded too great heat losses and such rapidly progressing destruction the refractory vaults surrounding the furnace, that also here the operation had to be given up quickly.

Die in der Zeichnung angegebene Anordnung soll die geschilderten Mängel vermeiden. Mit Dl, D9 .. . sind die Dampfkessel, Ri, R2 . . die maschinellen Roste, I' der Ventilator mit der den Feuerkanal umschließenden Saugeleitung S und der Druckwindleitung TV sowie mit K die nach Art eines Feuerkanals ausgebildete Vorfeuerung bezeichnet. Grundlegend bei der Erfindung ist die gemeinschaftliche Verwendung einer maschinellen Vorfeuerung unter Zwischenschaltung eines Feuerkanals K für mehrere Kessel gleichzeitig, wobei Kesselheizer gespart werden und die Lebensfähigkeit des Vorbaues bzw. des Feuerkanals durch Kühlung mit kalter Luft, die nach Bestreichen der heißen Wandungen wieder unter den Rosten oder anderweitig wirtschaftlich ausgenutzt werden soll, ermöglicht wird. Nach derZeichnung ist für je drei Kessel nur ein Doppelrost vorgesehen. Selbstverständlich ist auch jede andere Anordnung möglich.The arrangement given in the drawing is intended to avoid the deficiencies described. With Dl, D9 ... are the steam boilers, Ri, R2. . the mechanical grids, I ', the fan with the suction line S surrounding the fire channel and the pressure wind line TV, as well as with K the pre-firing designed in the manner of a fire channel. Fundamental to the invention is the common use of a mechanical pre-firing with the interposition of a fire channel K for several boilers at the same time, whereby boiler heaters are saved and the viability of the porch or the fire channel by cooling with cold air, which after coating the hot walls again under the grates or is to be used economically in some other way. According to the drawing, only one double grate is provided for every three boilers. Any other arrangement is of course also possible.
