Abstract
An apparatus for explosion suppression. The apparatus includes a flange proximate a volume wherein explosions are to be suppressed, a burst seal affixed to the flange, and a spreader insert proximate the flange. The seal is made to burst when pressure is applied to it. The insert defines apertures therethrough that form the shape of at least one annulus. The apertures are aligned with the seal, so that suppressant supplied to the insert passes through the insert into the protected volume. The insert directs suppressant passed therethrough under pressure with an effective explosion suppressing spread of at least 90 degrees.
