Returning the boiler into use after idle periods
Generally, it would be the local operators
who would return the boiler into use after
an idle period. Starting the boiler from
the external control room is not permis-
sible.
The boiler must be returned into use in
the following sequence:
■ Walk around the system to visually
check its correct condition
■ Control panel commissioning – Circuit
breaker ON
■ Commissioning the feed
■ Checking the water level and the func-
tion of the water level indicator as well
as that of the water level control
■ Commissioning the combustion with a
closed steam valve
Shutdown
Shutdown means shutting down the sys-
tem via the circuit breaker at the control
panel.

ter "Utilisation and operation".
