Función y descripción
Protection of Ethanol and Alcohols in Non-Pressurized Systems and Containers
The PROTEGO® BE/HK-E End-of-Line Deflagration Flame Arrester Deflagration flame arrester 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. The combustion of alcohol requires a modified Flame Arrester Flame arrester Device fitted to the opening of an enclosure, or to the connecting pipe work of a system of enclosures, and whose intended function is to allow flow but prevent the transmission of a flame. Element design to provide protection against endurance burning Endurance burning Stabilized burning for an unlimited time. . In addition, the device Device 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 Deflagration Explosion propagating at subsonic velocity. . It is typically installed on in-breathing and out-breathing vent lines to prevent flame transmission into the vessel Vessel 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/HK-E consists of the housing Housing 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 Weather hood A weather hood is a cover to protect the internal components of a device from environmental influences. (2), and the PROTEGO® Flame Arrester Unit PROTEGO® flame arrester unit The PROTEGO® flame arrester unit is the main component of a flame arrester. It prevents flame propagation. (3). During normal operation, the metal weather hood is in a closed position. If a stabilized flame burns on the Flame Arrester Element surface, the melting element Melting element 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 Spring 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 FLAMEFILTER® cage The FLAMEFILTER® cage is a housing for a FLAMEFILTER® set. .
For Explosion Group IIB1
The PROTEGO® BE/HK-E End-of-Line Deflagration Flame Arrester is available for alcohols and other substances with MESG ≥ 0,85mm. The standard design can be used for operating temperatures up to +60°C / 140°F. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
Dimensiones
To select the nominal size Nominal size The nominal size is an alphanumeric designation of size for components in a piping system, used for reference purposes, comprising the letters DN followed by a dimensionless integer that is indirectly related to the physical size of the bore or outside diameter of the connections, expessed in millimeters. (DN), please use the flow capacity charts on the following pages
