Function and Description

Protection against atmospheric deflagration and endurance burning

For many years the PROTEGO® BE/HR end-of-line deflagration Deflagration Explosion propagating at subsonic velocity (EN 1127-1:1997). flame arrester has been successfully used to protect 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 Endurance burning Stabilized burning for an unlimited time. . 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 PROTEGO® BE/HR 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 flame burns on the flame arrester element surface, the fusible link (5), located in a center position, will melt and let 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 move 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 groups IIA to IIB3

The FLAMEFILTER® gap size will depend on the devices intended use. Detailing the operating conditions such as the temperature, explosion Explosion Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. group and the composition of the fluid, enables PROTEGO® to select the best end-of-line deflagration flame arrester for your application. The PROTEGO® BE/HR series end-of-line deflagration flame arrester is available for substances from explosion groups IIA to IIB3 (NEC groups D to C MESG ≥ 0.65 mm). In a modified design, this device is also available for Ethanol applications. The standard design can be used with operating temperature Operating temperature Temperature reached when the equipment is operating under design conditions. of up to +60°C / 140°F. Type-approved according to ATEX Directive as well as other international standards.

Dimensions

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.

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”.
