The plant burns solid fuel at a pressure above atmospheric and comprises a combustion chamber (12), a bottom (28) with mouthpiece (32) in the chamber lower part for input of combustion air to fluidise the bubbling bed (34) of particle-form material, and for combustion of the fuel. A gas turbine (22) is driven by the combustion gases from the plant, a compressor (24) compresses the combustion air, and a multi-stage gas cleaning plant (14) incorporates several groups of gas cleaners (16, 18) arranged in series. - In the first cleaning stage, gas cleaners have their particle material outlet connected to the combustion chamber for re-circulation of sepd. material. They are also connected to a pressure reducing feed-out device and a collection container for sepd. material. The bottom of the combustion chamber is provided with an air chamber divided into upper (52) and lower (54) parts by a perforated horizontal intermediary wall (56) through which particle-free combustion air passes from the lower part to the upper part. - (Provisional basic advised week 90/23) (9pp Dwg.No.1/1) |
