A 456 MW combined cycle gas turbine power and water desalination plant needed to find an industrial cleaning contractor who could clean the condenser tubes within 5 of their heat recovery units during a short shutdown period. Having read about Tube Tech’s innovative darTT cleaning system on the internet, the plant were hopeful that Tube Tech could solve their problem.
The plant provides over 15% of the country’s peak system capacity and more than 30% of the country’s installed water capacity and is a relatively new facility.
Previous traditional contractors had only managed to clean a small percentage of the 15,780 condenser tubes in the previous outage and the plant operators were concerned that the remaining build up of scale was having a considerable effect on their heat transfer rates.
Scott Donson, Sales Manager: “We know that our darTT system is extremely effective on standard condenser deposits and were pleased with the way the pumps functioned in the excessive heat, however we were surprised by the thickness and volume of scale removed by the darTT projectiles, proving that the quality and rugged darTT design was a real benefit. We were able to remove an impressive amount of deposit, scale and debris to make a significant improvement on the heat transfer rate of the heat recovery units.”
