ABSTRACT:
A hot gas manifold system for a gas turbine power plant utilizing a pressurized fluidized bed combustor producing gas that is heated in two topping combustors. Each topping combustor is connected to a separate manifold. The manifolds, which are adjacent each other in a forward and aft arrangement, are disposed in the turbine shell between the compressor and turbine sections of the gas turbine and each forms a toroidal chamber that encloses the rotor. A plurality of ducts extend downstream from each manifold, with the ducts of the forward manifold extending through the aft manifold. Each of the ducts has an arcuate outlet that together form an annular hot gas path that matches the annular inlet to the turbine section. The ducts from each manifold form an alternating array so the hot gas from each of the individual topping combustors is symmetrically distributed around the turbine inlet.
