Fired heater decoking
Problem
Coke build-up inside fired heater tubes raises skin temperatures and pressure drop, cuts throughput and can damage tubes. Mechanical decoking restores the bore without burning out the heater, but needs detailed coil data and operating history.
What we do
We remove coke hydromechanically with high-pressure water tools driven through the coils. The pre-job questionnaire covers tube metallurgy, passes and bends, skin temperatures, coke condition and utilities so tooling and procedure match your heater.
What you get
Restored throughput and lower tube metal temperatures, avoiding thermal shock to the tubes, and a documented basis for the cleaning procedure.
Methods
Review of heater coil schemes and operating data.
Tool selection per pass, bend type and ID.
Hydromechanical decoking with progress control.
Debris management and tube condition check.
Post-job report with findings.
