Abstract

The steam generator has a fluidised bed combustion chamber (1) coupled on the flue gas side to at least one cyclone (5), each followed by a flow bed cooler (12). An immersion head (8) between the cyclone and the latter is coupled to the fluidised combustion chamber via a feedback line. The flow bed cooler, the immersion head and the cyclone are provided as a single unit contained within a common pressure vessel (19).
