HIGH PERFORMANCE LEVEL CONTROL
Max temperature in the Boiler Room is now 60°C
CONTROL PHILOSOPHY
PUMP PERFORMANCE IN LEVEL CONTROL Sensor range Cavitation Static pressure Min. speed
Level control Tank shape 20 t steam/h with 2,5 m3 water volume Basic control: Tank size is defined by inlet and discharge flow – how long time it will take to fill or drain the tank by the attached pump and valve. Time = Tank volume/Flow [sec = m3/(m3/sec)] 20 t steam/h with 18 m3 water volume Fast reacting - Low sensitivity Tank size: A large tank provides stability - it will fill and empty slowly. A large tank can be used as storage Slow reacting - High sensitivity
