Between 13/04/2014 to 15/04/2014

-          Unit 6 restart on by-pass operation.

-          Feed water flow tuning. This is the biggest interface problem (P02/P03/P17). PAC and Belfort still struggling to find the right settings to tune this loop. Most of the boiler trips are due to this function.

-          Boiler economizer soot blowing (Hitachi). The boiler tube have never been cleaned before: This may explain this difficulty to tune the boiler feed water flow.
