Tube Tech was contracted by a UK power station. Dust and ash accumulation of an economiser was causing heat transfer efficiency to drop. TTIL was able to use a bespoke lance adapted from their ROV convection section robot to remove the fouling. We were able to remove more than 95% of the fouling, in just 2 days. Heat transfer efficiency of the asset dramatically improved, With the client expecting to see a significant ROI and reduced CO2 emissions.
