   Weiters besteht die Möglichkeit, auch durch die Wirbelschicht entsprechende Rohrschlangen   --7-- hindurchzuführen,   um der Wirbelschicht - je nach Art des   Brennstoffs-Wärme   zu entziehen oder zuzuführen. 



   Die Wirbelluftdüsen umfassen kleine Rohrstutzen--3--, die von einem Verteilerrohr--1-in bestimmten Abständen abzweigen, und die schräg nach unten geneigt sind, damit kein grobstückiges Material darauf liegen bleiben kann. 



   PATENTANSPRÜCHE : 
1. Wirbelschichtfeuerungsanlage für Brennstoffe unterschiedlicher, insbesondere minderer Qualität mit unverbrennbarem Fremdkörpereinschluss, bei der für die Zufuhr des Fluidisierungsmediums und/oder der Verbrennungsluft rostartige parallele Rohre in oder unterhalb der Schichte des fluidisierten Brennstoffs mit schräg nach abwärts verlaufenden Öffnungen und/oder Rohrstutzen sowie Trichter zur Entaschung vorgesehen sind, dadurch gekennzeichnet, dass im Trichter

   There is also the possibility of passing corresponding coils --7-- through the fluidized bed in order to extract or supply heat to the fluidized bed, depending on the type of fuel.



   The vortex air nozzles include small pipe sockets - 3-- which branch off from a distributor pipe - 1-at certain intervals and which are inclined downwards so that no coarse material can remain on them.



   PATENT CLAIMS:
1.Fluid bed combustion plant for fuels of different, in particular inferior quality with incombustible foreign matter inclusion, in which for the supply of the fluidization medium and / or the combustion air, rusty parallel pipes in or below the layer of the fluidized fuel with obliquely downward openings and / or pipe sockets and funnels Ash removal is provided, characterized in that in the funnel
