Abstract. Presently, within the framework of solving the problem of improving production efficiency, the
efforts of oil refineries are aimed at increasing the turnaround periods of process units. One of the effort
ways to increase the turnaround periods is to increase the reliability of the process furnaces.
With a view to increase the service life of the Refinery process unit furnace coiled pipes and, accordingly, to increase the safety of the technological process, as well as to reduce the cost of the coiled pipe recovery, a number of works were carried out to inspect and adjust the combustion mode in the process furnaces using an infrared flame imager. Based on the results of the work performed, a
method for eliminating overheating of the steam reforming furnace coiled pipes was developed.
The use of this technique allows maintaining the temperature of the coiled pipes within the standard
values, increase the service life and increase the reliability of process furnaces.
