Abstract

Aus porösen, gasdurchlässigen Keramiksteinen (5) bestehende Böden für Wirbelschichtöfen weisen bei stark variieren­ den Temperaturen der sie durchströmenden Gase nur kurze Standzeiten auf. Um die Standzeiten erheblich zu erhöhen werden von der Ofenkonstruktion getragene schmale, sich quer zur Längsachse des Ofens erstreckende geschlossene, mit einem Anschluß zur Zuführung von Gasen vorgesehene Gaskammern vorgesehen, deren Oberseite in regelmäßiger Teilung Ausnehmungen (3) aufweist, sowie durch jeweils auf eine Ausnehmung gestellte, metallummantelte poröse Keramiksteine (5), bei denen die Böden der Mäntel (4) je eine den Ausnehmungen (3) entsprechende und mit diesem kommuni­ zierende Öffnung (6) aufweisen, und bei denen der Mantel (4) auf einen übergestülpten, den Mantel (4) mit abgekanteten Randstreifen umgebenden und mindestens eine Öffnung (9) auf­ weisenden Deckrahmen (8) geschlossen ist. Porous, gas-permeable ceramic stones (5) Floors for fluidized bed furnaces vary widely the temperatures of the gases flowing through them only briefly Downtimes. To increase the service life considerably are narrow, supported by the furnace construction closed, transverse to the longitudinal axis of the furnace provided with a connection for supplying gases Gas chambers provided, the top of which in regular Division has recesses (3), and by each a recessed, metal-coated porous Ceramic stones (5), in which the bottoms of the coats (4) each have one corresponding to the recesses (3) and communicating with this have decorative opening (6), and in which the jacket (4) on an overturned, the jacket (4) with folded Border surrounding and at least one opening (9) facing cover frame (8) is closed.
