ABSTRACT:
A reaction chamber with a fluidized bed encloses two superposed cyclone separators connected in series. In order to prevent combustion gases from entering the lowermost separator by way of its particulate matter outlet, this is formed as a downwardly extended pipe, which is enclosed by a sleeve through which secondary air passes. The sleeve projects somewhat below the mouth of the pipe, and the issuing air causes an ejector action, which prevents gas from entering the pipe. The particulate matter return flow pipe from the upper cyclone is also extended downwards and terminates within the ejector.
