Abstract

It has been experimentally shown that a complex obstacle consisting of two confusers oriented in opposite directions of a cylindrical vessel completely prevents the propagation of diluted methane - oxygen flames, i.e., the obstacle is the most effective flame arrester; the theoretical predictions are consistent with the experiments.
