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.

Losses In Steam Turbine - Mechanicaltutorial

This loss is about 10 to 12% in a single stage turbine. 7. Loss in regulating valves :-Before entering the steam to the turbine, it passes through the boilers stop and regulating valve. Steam gets throttled in these regulating valves and as a result steam pressure will be less than the boiler pressure at the entry of turbine.
