Protection Against Atmospheric Deflagration and Endurance Burning
The PROTEGO® BE/HR-E End-of-Line Deflagration Flame Arrester Arrête-flammes antidéflagration Flame arrester designed to prevent the transmission of a deflagration. It can be an end-of-line flame arrester or an in-line flame arrester. was specifically developed for vessels which are not pressurized and store Ethanol or other alcohols with a MESG ≥ 0,85 mm. The combustion of alcohol requires a modified Flame Arrester Element design to provide protection against endurance burning Endurance burning Stabilized burning for an unlimited time. . In addition, the device Appareil A device is a pipe component that influences the media flow by opening, closing, or partially shutting off the flow channel or by dividing or mixing the media flow. provides protection against atmospheric deflagration. It is typically installed on in-breathing and out-breathing vent lines to prevent flame transmission into the vessel Récipient Container or structural envelope in which materials are processed, treated or stored. or plant caused by endurance burning or atmospheric deflagration.
Main Component – PROTEGO® Flame Arrester Unit
The PROTEGO® BE/HR-E consists of the housing Corps A housing is a solid shell, which surrounds a content, either protecting the content from external influences, or protecting the environment from the content. (1), a weather hood Capot de protection contre les intempéries A weather hood is a cover to protect the internal components of a device from environmental influences. (2), and the PROTEGO® Flame Arrester Unit (3). During normal operation, the metal weather hood is in a closed position. If a flame burns on the Flame Arrester Element surface, the melting element Elément fusible The melting element is a component that consists of a housing with a lower and upper part. (5), located in a center position, will melt, and the spring Ressort A spring is a spiral of wire which returns to its original shape after it is pressed or pulled. -loaded weather hood will open. The PROTEGO® Flame Arrester Unit consists of two FLAMEFILTER® discs (4) which are installed in a FLAMEFILTER® casing.
