DESIGN CRITERIA FOR FLAME CONTROL DEVICES FOR CARGO VENTING SYSTEMS
Devices used to prevent flames from traveling into bulk cargo tanks through the venting system were studied, with emphasis on screens and arrestors for heat abstraction. The evidence indicates that low-speed flames can be quenched by an array of small passageways placed in the vent duct, provided the passageway diameter is less than 60 alpha/S, where alpha and S are the thermal diffusivity and laminar flame speed of the vapor/air mixture. Expressions are given for effective passageway diameter of flame screens, crimped ribbons, packed beds, and other common heat abstraction devices.
