7 Summary of deviations noticed during the audit

7.1 Steam generation

Steam is produced by the Energy Central 2 since 2010. This new boiler house is not well monitored

yet.

Gas meters data on the 2 steam generators are not read regularly. As natural gas is also used for

hot water boilers in the Energy Central 1, it is not possible at the moment to know exactly fuel

consumption used to produce steam.

The make-up water meter is reported every day during the daily maintenance (decalcify water).

Some other data are measured and reported to the BMS System:

However some of these probes do not work properly (stacks temperatures, steam temperature) and

only steam pressure is recorded (trends available).

Consequently it is not possible to check on a regular basis the good functioning of the new boiler

house.
