Tube Tech recommended the use of its condenser polishing system used in conjunction with their newly bespoke darTT de-scaling system for speed. The work was required within a short window of opportunity. It is particularly effective on light-to-medium deposits such as the fouling found at this EON site and in excess of 5,000 tubes can be cleaned by one operative per day using the darTT system.
The speed and safety of the combined DarTT & condenser cleaning method meant that the Tube Tech operatives could minimise downtime at the site. The fouling factors in the condenser were reduced significantly within this short two-day operation from 0.16m2K/kW to 0.01m2K/kW, boosting electricity generation performance by a massive 20 mega-watts (MW) per hour. This new level of performance equates to a cost saving in the region of £4 million over a year’s operation from this one condenser.
