Function and Description

Protection against atmospheric deflagration and endurance burning

The PROTEGO® BE/HR-400 end-of-line deflagration Deflagration Explosion propagating at subsonic velocity (EN 1127-1:1997). flame arrester is designed to protect large vessels and process engineering apparatus which are not pressurized. 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 flame transmission through atmospheric deflagration and stabilized flames which can burn for very long time on the flame arrester element surface, so called endurance burning. Main application area is on in- and out-breathing and vent lines, with the goal to prevent flame transmission caused by endurance burning or atmospheric deflagration from propagating into the vessel Vessel Container or structural envelope in which materials are processed, treated or stored. or plant.

Main component - PROTEGO® flame arrester

The BE/HR-400 consists of a 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 (2) and the PROTEGO® flame arrester unit (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 fusible link (5), located in a center position, will melt and an external counterweight will move the weather hood into the open position. The PROTEGO® flame arrester unit consists of two FLAMEFILTER® discs (4), which are installed in a FLAMEFILTER® casing FLAMEFILTER® casing Enclosure for FLAMEFILTER® including insert rings. .

For Explosion group IIA

The FLAMEFILTER® discs are arranged concentrically and are manufactured in a patented process. The FLAMEFILTER® casing has integrated cooling channels to allow heat to be transferred away from the center of the device. The PROTEGO® BE/HR-400 end-of-line deflagration flame arrester is available for substances from explosion group IIA (NEC group D). 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.

Flow Capacity Chart

The flow capacity charts have been determined with a calibrated and TÜV certified flow capacity test rig. Volume flow V in (m³/h) and CFH refer to the standard reference conditions of air ISO 6358 (20°C, 1bar). For conversion to other densities and temperatures refer to Sec. 1: “Technical Fundamentals”.
