Eone Hydrogen Dryer GGDII - Nuclear Plant of Ascó

Installation of a hydrogen dryer in alternators 1 and 2 at the nuclear Plant of Ascó.

Application

Hydrogen dryer for the Siemens-Westinghouse generators (1000MW) of sets 1 and 2 at the Nuclear Plant of Ascó.

The problem

The dryers at sets 1 and 2 of the plant were obsolete and not very efficient, which made them difficult to maintain and operate. Also, this was a risk since they did not comply with the ATEX directive.

The solution

Dryer GGD2 manufactured by Eone integrates the latest advances in hydrogen treatment for eliminating humidity inside the generator. Their Regenex system allows removing all the trapped water with minimum hydrogen consumption.

The results

After several months of operation, the amount of humidity inside the generator has remained extremely low and has been monitored at all times by the built-in dew point sensors in GGD2. This information is permanently supervised from the control room and allows the plant to operate with greater efficiency and complete safety.
