Drum level very high / low
Source : Hydrastep and drum level transmitter
Implication:
High: Will result in Flooding of superheaters causing
a. carryover of dissolved solids and hence deposition downstream effecting heat transfer
b. fall of steam temperature and quenching of Turbine Low: Will result in starvation of water in the furnace tubes which will lead to tube metal overheating as no cooling medium is present
Action: MFT
