Abstract

A pressurized combustion chamber with fluidised bed (8) is equipped with a silo (15) for extra bed material. The fluidised bed and silo are connected with infeed and outfeed tubes (16, 17) for the transport of material between the bed and silo to regulate bed height during varying load. The infeed tube (16) is bent like a so-called L-valve. In order to blow material in through this tube, it is connected to a pressure vessel (9) that surrounds the bed by means of a valve (18). The outfeed tube (17) is connected to the silo via a whirler (23) for the separation of material from the bed to the silo. This whirler is connected the output side of the combustion chamber via a valve (19) for the evacuation of material from the bed to the silo through the outfeed tube. To ensure equilibrium in the silo at constant load, the infeed and outfeed tubes (16, 17) discharge at the same level in the bed, preferably at the bottom. Different chokes (22, 24, 29) can be introduced in the air tubes to control airflow during infeed and outfeed.<IMAGE>
