Increasing Furnace Efficiency With Hot Convection Cleaning

PROBLEM

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

SOLUTION

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

OUTCOME

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

Fouled convection section tubes.

Convection section tubes after Hot-tek cleaning.

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
