Notes:
Deflagration suppression is one of several means of explosion protection for process volumes. This paper presents a discussion of some of the variables which influence the final pressure obtained upon suppression of a process deflagration. In particular the discussion focuses on suppression of the deflagrations of fast burning dusts, i.e. dusts with high Kst values. The discussion is amplified using recently obtained data from deflagration and suppression tests on three flammable dusts representing the St-2 and St-3 deflagration classes. It is shown that the relationship between post-suppression pressure and Kst value is not always as expected. The underlying reason for this result relates to differences in the burning characteristics of the subject dusts in the relevant stages of the deflagration.
