EB-Z
Deflagration Flame Arrester, endurance burning proof, End-of-Line
- protection against atmospheric deflagration and endurance burning of pure hydrocarbons
- weather hood protects against environmental impact (i.e. weather, bird nests, etc.)
- modular design allows replacement of single FLAMEFILTER®
- easy maintenance
- modular design results in low spare part costs
- low operating and lifecycle cost
- cost effective protection for small vessels and process engineering apparatus
Функция и описание
The PROTEGO® EB-Z end-of-line deflagration flame arrester has been successfully used to protect small vessels and process engineering apparatus which are not pressurized. The device 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 outbreathing 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-Z consists of a housing (1), a weather hood (2) and the FLAMEFILTER® (3). The weather hood is made out of acrylic glass, which will melt when impacted by flames and allow heat to dissipate to the environment. The PROTEGO® EB-Z serie end-of-line deflagration flame arrester is available for substances of explosion group IIA (NEC group D MESG > 0.90 mm)
The standard design can be used for operating temperatures up to +60°C / 140°F.
Type-approved according to ATEX Directive and EN ISO 16852 as well as other internationally accepted standards.

Диаграммы пропускной способности
Диаграммы пропускной способности были определены с помощью калибрированной и сертифицированной объединением технического надзора (TÜV) проточной измерительной установки. Пропускная способность V. в м³/час определена воздухом при нормальных атмосферных условиях в соответствии с ISO 6358 (20°C, 1 бар). Преобразование для различных плотностей и температур см. главу 1: Технические основы
