Abstract: A gas turbine plant having a combustion chamber (1) separate from the turbine (15) includes a conduit (16) with an inner tube (17), which conducts heated propellant gas from the combustion chamber (1) to the turbine (15); and an outer tube (18), which surrounds the inner tube (17) to form an annular gap (20) which conducts compressed air from a compressor (10) to the combustion chamber (1). (FIG. 1.

Abstract: A fluidized bed combustion chamber adaptable for use with relatively large gas turbines and the like, wherein a substantially spherically-shaped outer casing encloses an annular fluidized bed combustion chamber which is mounted on a double bottom air distribution box. A cleaning assembly is positioned within the fluidized bed and the entire combustion chamber is supported on a base plate which extends through the casing and into contact with the box. Compressed air enters the spherical casing, is directed through a pair of cooling gaps, is caused to enter the air distribution box and then passes through the fluidized bed.
