Deflagration Flame Arrester, endurance burning proof, End-of-Line

Función y Descripción

The PROTEGO® EB end-of-line deflagration flame arrester has been successfully used to protect vessels and plants which are not pressurized. The device provides protection against 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 suction and vent lines, with the goal to prevent flame transmission caused by endurance burning or atmospheric deflagration from propagating into the vessel or plant.

The PROTEGO® EB consists of the PROTEGO® flame arrester unit (1) and the metal weather hood (2). 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 (3), located in a center position, will melt and let the spring loaded weather hood move into the open position. The PROTEGO® flame arrester unit consists of one or more FLAMEFILTER® (5), which are installed in a FLAMEFILTER® cage (4), a intersecting ribs (6) and a spider ring (7). The FLAMEFILTER® gap size, the height and the quantity depend on the devices intended use.

The PROTEGO® EB series end-of-line deflagration flame arrester is available for substances from explosion group IIA and IIB (NEC group D and B).

The standard design can be used with operating temperature of up to +60°C / 140°F.

Type-approved in accordance with ATEX Directive and EN ISO 16852 as well as other international standards.
