Spud's blog: Boiler Drum Level Control

The boiler drum level control valve can be placed either at the economizer inlet or outlet. There are significant disadvantages with each arrangement, both of which occur during start-up. During start-up, when boiling first occurs, drum level will increase rapidly, because steam bubbles begin lofting slugs of water up out of the furnace into the drum.
