Claim 12:
13. A cleaning system for cleaning coils in a fired heater, comprising:
a data acquisition tool configured to pass through the coils to acquire data;
wherein the cleaning system is configured to establish a pre-cleaning fouling baseline derived from the data for the coils, and wherein establishing the pre-cleaning fouling baseline comprises:
identifying at least one fouling area, and
establishing a location in the coils for the at least one fouling area;
wherein the cleaning system is configured to develop an optimized cleaning plan for the coils based on the pre-cleaning fouling baseline, and wherein the optimized cleaning plan comprises a focused cleaning for the at least one fouling area;
at least one cleaning pig configured to clean the coils based on the optimized cleaning plan; and
a decoking truck for cleaning the coils based on the optimized cleaning plan and configured to drive the at least one cleaning pig through the coils to perform the focused cleaning on the at least one fouling area with the at least one cleaning pig, and to monitor the location of the at least one cleaning pig within the coils of the fired heater in in real-time.
