The safety integrity level (SIL)assessment technology for heating furnace’s safety interlocking sys-tem was developed to analyze both necessity and sufficiency of the safety interlocking system for typical heating furnaces in the petrochemical plant.Through evaluating safety interlocking functions(SIF)of five sets of typi-cal heating furnaces,the reasons of the safety interlocking system’s lack of security and high rate of nuisance trip were analyzed,and the suggestions on improving the furnace’s interlocking system were presented.
