Drum level low its interlock with ID fan.If drum level is
low then ID fan will tripped.If ID fan tripped then PA fan
will tripped after PA fan tripped FD fan will tripped.

Answer / nani babu

drum level interlock is fd fan ie drum level ismlow fd fan
tripped

Answer / r.murugan

Dear santhu,
During normal boiler operation if drum level low (means drum pressure is high) during that time drum kevel controller will take care if not maintain that time further going level lowlow boiler will trip

Answer / dilip jha

If drum level is low , firstly ID fan will trip then FD fan tripped then PA fan will Tripped.
This is the interlock of Drum Level Low.
