Density Error and its Correction in Boiler Drum Level

in Boiler Drum Level Indication INTRODUCTION Boiler steam drum water level is one of the most important power plant para-meters to measure and control. If the level is too low, boiler tubes will be damaged by overheating. If the level is too high, the superheater tubes and the turbine may be damaged by mois-ture or water treatment chemical car-ryover.
