Increasing Furnace Efficiency With Hot Convection Cleaning


Crude Heater with significant process preheat was overfiring. Convection tubes were fouled leading to High Bridgewall and High Stack temperatures.


IGS performed Hot-Tek cleaning through existing access doors on an existing platform.


Total absorbed duty increased with a decrease in firing leading to Increased Furnace Efficiency.

Eliminating Fouling for Efficient Operation

The application of the Hot-Tek solution while the fired heater was in operation has helped achieve a number of benefits, including:

  • Increase process pre-heat and steam production
  • Reduce stack temperature
  • Improve draft
