In the combined cycle design (Fig. 6.33), the flue gas from the PFBC boiler enters the hot gas clean-up system at about 1600°F. After passing through the hot gas clean-up system and expanding in the gas turbine generator, the flue gas passes through a heat recovery steam-generator and conventional bag-house or ESP filter.
