Would a high inlet and 1st stage pressure be indicative of blade deposits? What other facors or operational practices would cause this? Any mre information required, pls contact me.

RE: Steam Turbines
What is your output power change that does/does not correspond to the perceived change in inlet & 1st stage pressure?
Have changed anything else: from the water treatment/lack of treatment to the pumps to the boiler to the valve program or control valve? have you done any recent maintenance - anywhere in the system? I found once a complete pipe support set wrapped around the 3rd and 4th stage blades of a HP turbine that had come from a vender working inside pipes upstream of the control valves .... Yeah - THAT little bit of blockage caused some dp changes.
