Abstract

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 with at least first and second or final stages disposed in a flue gas pass with the superheater upstream of the final stage reheater has a cold steam bypass system for controlling the temperature of the second or final stage reheater by dividing reheat steam into selective first and second portions and directing the first portion to the first stage reheater and recombining said first and second portions and directing them through the second or final stage reheater.
