MFT – Drum level very high/low

Drum level very high / low

Source : Hydrastep and drum level transmitter


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
