Claim 16:
17. A method for cleaning coils in a fired heater in a cleaning operation, comprising:
locating a decoking truck on-site with the fired heater to perform the cleaning operation;
coupling the decoking truck to the coils of the fired heater;
sending a data acquisition tool through the coils to acquire data;
establishing a pre-cleaning fouling baseline derived from the data, 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;

developing 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; and
cleaning the coils based on the optimized cleaning plan with at least one cleaning pig, and wherein the cleaning comprises:
driving the at least one cleaning pig through the coils with the decoking truck,
performing the focused cleaning on the at least one fouling area with the at least one cleaning pig, and
monitoring with the decoking truck the location of the at least one cleaning pig within the coils of the fired heater in real-time.
