Abstract
A suppressant delivery and release nozzle structure is disclosed for an explosion protection system. The nozzle is a reducing elbow, concentric or eccentric mounting a rupture disc at its small end. A selectively actuatable detonator housed in the nozzle adjacent the disc permits substantially instantaneous opening of the disc upon command for release and delivery of suppressant to a zone to be protected from an explosion hazard. The configuration of the nozzle assures unimpeded discharge of suppressant from the system in a minimum of time without significant two-phase flow. The nozzle is equally adaptable for liquid or powdered suppressant compositions.
