Function and Description

Protection of Fuel Supply Lines

The PROTEGO® FA-G-IIA1-P2.2 in-line deflagration flame arrester In-line deflagration flame arrester A deflagration flame arrester is designed to prevent the transmission of a deflagration. An in-line deflagration flame arrester is equipped with a pipe connection on both sides. was specially developed for bio-, sewage- and landfill-gas applications. The compact design of the PROTEGO® FA-G makes it the state of the art technology for installation in pipes with diameters of ½” up to 2”. The devices are installed with minimal distance to the burner to prevent flashback Flashback Phenomenon occurring in a flammable mixture of air and gas when the local velocity of the combustible mixture becomes less than the flame velocity, causing the flame to travel back to the point of mixture. in to the fuel feed lines. When installing the deflagration Deflagration Explosion propagating at subsonic velocity (EN 1127-1:1997). flame arrester, make sure that the distance between potential ignition sources and the location of the installed 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. , does not exceed the L/D ratio (pipe length/pipe diameter), for which the device was approved. As per EN ISO 16852 the L/D ratio is limited to (L/D) max ≤ 50 for deflagration flame arresters Deflagration flame arrester Flame arrester designed to prevent the transmission of a deflagration. It can be an end-of-line flame arrester or an in-line flame arrester. of explosion group IIA1.

For Explosion group IIA1 - Methan

The in-line deflagration flame arrester is symmetrical and offers bidirectional flame transmission protection. The device consists of two 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. parts (1) and two FLAMEFILTER® (2) in the center. The PROTEGO® FA-G-IIA1-P2.2 flame arrester protects against deflagrations and endurance burning Endurance burning Stabilized burning for an unlimited time. (under atmospheric condition Atmospheric conditions Atmospheric conditions are pressures from 80 kPa till 110 kPa and temperatures from -20°C up to +60°C. ) and short time burning Short time burning Stabilized burning for a specific time. for 1 min. for the maximum operating conditions of explosion group IIA1 - methane.

Many Individual Certifications

PROTEGO® FA-G devices for substances of explosion groups IIA, IIB3 and IIC (NEC groups D, C, and B) are shown on separate pages. The standard design can be used up to an operating temperature Operating temperature Temperature reached when the equipment is operating under design conditions. of +60°C / 140°F and an absolute operating pressure Operating pressure Operating pressure is the pressure existing at normal operating conditions within the system being protected. up to 2.2 bar / 31.9 psi. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.

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”.
