  • Patent number: 4281510
    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.

  • Patent number: 4269151
    Abstract: A pressurized combustion chamber assembly wherein a fluidized bed extends in a longitudinal direction through an elongated, cylindrically shaped outer casing. A multi-stage cleaning plant is positioned within the casing, whereby a plurality of cleaning devices are each connected in parallel to an outlet of the fluidized bed and a plurality of second stage cleaning devices are each connected to an outlet of one of the first stage cleaning devices, respectively. The combustion chamber assembly is formed from a plurality of separate prefabricated chamber modules separably attached to one another.

  • Patent number: 4237800
    Abstract: A cleaning plant positioned within an annular fluidized bed combustion chamber is divided into a plurality of separate cleaning stages, wherein a first stage is located adjacent the fluidized bed and additional stages are arranged within the first stage. Each stage comprises a plurality of separate cleaning devices which act in parallel, while cleaning devices of different stages act in series to remove debris from the combustion gases that exit from the fluidized bed combustion chamber.

  • Patent number: 4237823
    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.
