High pressure air lancing had proven to be ineffective at removing hard deposits residing in between studded and bare convection tubes within a fired heater. The refinery chose Tube Tech’s advanced robotic system as it guaranteed the removal of deposits to improve heat transfer, reduce stack temperatures and fuel consumption, and improve overall throughput.
