Refining: Hot Tube Descaling
Cetek’s patented Hot Tube Descaling Process (HTD) removes radiant section process tube scale & fouling during furnace operation. The HTD process uses unique water-cooled lances which ensure continuous scale removal and maximum cleaning while the heater continues to function normally. The process utilizes consumable abrasive media resulting in no increase in emissions. In some applications, Cetek's LancescopeTM system is used to see hard to reach areas. In addition, Cetek has the capability to safely create engineered access ports that can be used to facilitate the HTD process and in the future.
Typical results of the HTD process include bridgewall temperature reduction of 50°F (10°C) to 100°F (38°C).
