Abstract

The paper considers the possibility of assessing the development of accidents on the basis of a system-functional approach applied to the analysis of the probability of accidents in soda recovery boilers (SRBs). The main attention is paid to identifying the most vulnerable elements of the SRB and the possibility of diagnosing and preventing accidents based on the development of diagnostic systems in the existing APCS systems of the most important section of the SRB - the black liquor combustion system.
