The analysis of technological processes for a real control object-a recovery boiler is performed in order to determine faults and possible emergency situations. The recovery boiler is considered as a complex control object (in which a chemical reactor is combined with a steam power boiler), which is advisable to decompose into several interconnected subsystems. The study was carried out in accordance with the HAZOP application manual in the form of a qualitative analysis of faults and possible abnormal situations in the recovery boiler. The study was conducted in accordance with the decomposition of the recovery boiler for each constituent of the interconnected subsystems. As a result of research, for each of the subsystems of the recovery boiler, HAZOP work tables were developed that allow you to identify root frames-linked to specific causes of possible faults.
