Abstract

Bei Wirbelschichtfeuerungen mit stationärer Wirbelschicht wird Sekundärluft in den Freiraum (10) über der Wirbel­ schicht (6) eingeblasen, um die in dem aufsteigenden Gas noch enthaltenen brennbaren Substanzen auszubrennen. Wich­ tig ist dabei die homogene Einmischung der Sekundärluft und die Aufrechterhaltung einer Mindesttemperatur im Frei­ raum (10). For fluidized bed firing with a stationary fluidized bed becomes secondary air in the free space (10) above the vortex layer (6) blown to the in the rising gas burn out any flammable substances it contains. Wich What is important here is the homogeneous mixing of the secondary air and maintaining a minimum outdoor temperature room (10).

Aufwärts gerichtete Sekundärluftdüsen (14) sind injektor­ artig in senkrecht angeordnete, über die Fläche der Wir­ belschicht (6) verteilte, oben und unten offene Rohrstücke (13) hineingerichtet, die mit ihren unteren Enden in die Wirbelschicht (6) eintauchen und mit ihren oberen Enden in den Freiraum (10) hineinragen. Durch Injektorwirkung wird heißes, körniges Material aus der Wirbelschicht (6) von der Sekundärluft mitgerissen und in den Freiraum (10) geschleudert. Dadurch wird dem Freiraum (10) Wärme zuge­ führt. Außerdem wird die Einmischung der Sekundärluft in das aus der Wirbelschicht (6) aufsteigende Gas verbessert. Secondary air nozzles (14) pointing upwards are injector well arranged in vertical, over the surface of the we Coated layer (6) distributed, open pipe sections above and below (13) arranged with their lower ends in the Immerse the fluidized bed (6) and with its upper ends protrude into the free space (10). Through injector action becomes hot, granular material from the fluidized bed (6) swept away by the secondary air and into the free space (10) hurled. This gives the free space (10) heat leads. In addition, the interference of the secondary air in the gas rising from the fluidized bed (6) is improved.
