If, despite the observance of the starting
and operation control procedures danger-
ous situations should arise, such as the ab-
sence of water, breakage of under pressure
parts, explosion smoke side etc., it is nec-
essary to quickly intervene by shutting off :
- the fuel
- the power supply
3.18 - INSTRUCTIONS FOR STOPPING THE
GENERATOR
- Purge, with rapid openings, the generator and the level indica-
tor (operation to be carried out daily even in case of continu-
ous operation of the generator);
- close the main steam intake valve;
- remove power to the control panel;
- close the power supply circuit.
In these conditions the system is completely
"isolated" with respect to the branch out of
the control unit; the generator will slowly cool
without risk and will be ready to restart quick-
ly returning to normal operation.
NOTE
If the shutdown period is such to bring the
generator below 100°C, it will go "Vacuum";
this does not entail any particular problems
except for the auto fi ll of water for poor seal
of the shut-off valves on the supply line (i.e.
due to the eff ect of the starting manoeu-
vres).
3.19 �-� INSTRUCTIONS FOR THE EMERGEN-
CY STOP OF THE GENERATOR
ATTENTION!
IF THE FAULT IS CAUSED BY LACK OF WA-
TER IN THE GENERATOR, CAUSING THE
SHEET METAL TO BECOME RED-HOT, IT
IS STRICTLY FORBIDDEN TO INTRODUCE
COLD WATER; FOR SAFETY PURPOSES,
CUT OFF THE SUPPLY LINE.
When the system is cold, inspect the gener-
ator to assess the damage and identify the
causes that have led to the fault.
