Hot Convection Cleaning (HCC)

Removing Fouling & Scale During Furnace Operation

Is the convection section in your fired heater suffering from sub-par performance? Low steam production, low process pre-heat, and high stack temperature are some of the symptoms of fouled tubes.

Cetek’s Hot Convection Cleaning Process (HCC) removes convection section tube fouling & scale during furnace operation. The process uses consumable abrasive media projected through specially designed application lances to blast away years of accumulation, while the heater is in service.

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 both to facilitate the HCC process and for future access.Cetek HCC is efficient, environmentally friendly, and safe for the removal of years of fouling and scale without interruption to production.

Typical results of the HCC process include:

• Increased heat transfer efficiency in convection section
• Increased steam production
• Increased process pre-heat
• Lower stack temperatures
