ABSTRACT:
A power plant with combustion of a fuel in a fluidized bed is enclosed within a bed vessel. It includes one or more cleaners for separating dust from the combustion gases leaving the bed. The gas cleaner is built up as a panel or unit with a number of parallel-connected centrifugal cleaners, with a first cylindrical inlet part with guide vanes which impart a rotating movement to the gas flowing through, and a second cylindrical part sliding into the first part and together with this forming an annular gap with an outlet which communicates with a common space and/or with a separator arranged in series with the parallel separators. The panel or unit is directly connected to an outlet opening from the bed vessel and forms part of a bed vessel wall.
