Boiler Steam drum internals and function -

Boiler water in the steam will cause scaling of the superheater and steam turbines. Baffles, chevron types separators and demister pads are used to minimize boiler water carryover. The demisters coalesce the smaller drops into larger drops so that they will settle back into the water phase.

Common Steam Boiler Problems & How to

Low water cutoff valves shut off the boiler if the water level drops too low. Checking the operation of these should be a part of the job of someone in the building. Drain the tank for a few seconds to test the float chamber whenever its not in a firing sequence. The low water control system should kick in immediately.
