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

Función y Descripción

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 al-low heat to dissipate to the environment.

The PROTEGO® EB-Z serie end-of-line deflagration flame arrester is available for sub-stances 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.

Características especiales y ventajas

  • 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

Diagrama de flujo volumétrico

Los diagramas de flujo volumétrico han sido determinados con un banco de pruebas de caudal calibrado y certifi - cado por TÜV. El flujo volumétrico V. en [m³/h] y el CFH se refi eren a las condiciones estándar de referencia de aire según ISO 6358 (20°C, 1bar). La conversión a otras densidades y temperaturas están referidas en el Vol. 1: “Fundamentos Técnicos”.
