Abstract (en)

[origin: WO9008917A1] A steam generator having a fluidized bed combustion system that includes a fluidized bed combustor and at least one hot separator, includes a superheater and a reheater. A first stage of reheater and a second stage or final stage of reheater are sequentially disposed in a common gas flue. Cold steam from a turbine is divided into selective first and second portions, the first portion being directed through the first stage of reheater and thereafter recombined with the second portion of cold steam. The recombined first and second portions of steam are directed through the second stage of reheater.
