    When the steam pressure in boiler drops there are many reason why this happens. The instrumentation in the boiler system gives good indication as to which parameter the operator will have to address. However a coordinated effort of the boiler turbine generator operators in the control room along with the local operator is needed to restore the unit operating condition back to normal.
