- Scale formation in evaporator
- Jacket cooling water temperature lower than prescribed
- Short cycling of jacket cooling water
- Air stay in evaporator
- Faulty solenoid valve
- Faulty flow-meter
- Check the vacuum
- Leakage in the plant like from pressure gauge, vent, distillate pump seal

- Incorrect feed
- Nozzle choked
- Ejector malfunctioning due to worn parts
- Faulty ejector nozzle

Interlocks are provided so that the engine can be started or reversed only when certain conditions have been fulfilled. When there is a remote control of engines, it is essential to have interlocks. This reduces the possibility of engine damage and any hazards to the operating personnel. Turning gear Interlock . This device prevents the engine from being started if the Turning gear is engaged. Running Direction Interlock . This prevents the fuel from being supplied if the running direction of the engine does not match the Telegraph. Starting Air Distributor in end position . This prevents starting from taking place if the shifting of the Distributor has not been completed. Main Lube. oil pressure, Piston cooling pressure, Jacket water pressure, and important parameters must be above the required minimum. Auxiliary Blower Interlock . The Auxiliary Blower is provided in case of Constant pressure turbo charging. Air Spring pressure Interlock . In case of the present generation...
