Hot Tube Descaling

You may need Hot Tube Descaling if your radiant section hitting design limits, such as Bridge Wall Temperature.

Increase of Bridge Wall Temperature can be a symptom of excessive fouling of the radiant tubes. The steel alloy tubes typically used in fired heaters. These tubes tend to oxidize under operating conditions and layers of scale can grow to a degree that it insulates the tube from the radiant heat. It is even more dangerous if there are  several years until the next scheduled shut down.

Hot Tube Descaling

Cetek’s patented Hot Tube Descaling Process removes radiant section process tube scale & fouling during furnace operation. The hot tube descaling process uses unique water-cooled lances. We ensure continuous scale removal and maximum cleaning of the tubes while the heater continues to function normally. The process utilizes consumable abrasive media resulting in no increase in emissions.

In some applications, we use Cetek’s LancescopeTM system to see hard to reach areas. We also have the capability to safely create engineered access ports that can be used to facilitate the hot tube defouling process.

Typical results of the hot tube descaling process include bridgewall temperature reduction of 50°F (10°C) to 100°F (38°C). Dozens of our customers note rapid payback from using this service.
