Technical Fundamentals Flame Arresters Flame Arresters Development Flame arresters protect systems subject to explosion hazards from the effects of explosions. Ever since methane gas explosions were successfully suppressed in the mining industry in the mid-19th century by the development of the mine shaft lamp with a Davy screen, solutions have been found for making systems safer in modern hydrocarbon chemistry, where much more hazardous gases are used. In addition, filling stations became necessary with the introduction of the automobile. With filling station tanks, the problem of...

Combustion Processes Explosive mixtures can burn in various ways. The following, among other things, can influence the combustion process: the chemical composition of the mixture, possible pressure waves, pre-compression, the geometric shape of the combustion chamber, and the flame propagation speed. The relevant combustion processes for flame arresters are defined by international standards: Explosion is the generic term for abrupt oxidation or decomposition reaction producing an increase in temperature, pressure or both simultaneously [also see EN 1127-1]. Deflagration is an explosion...

Technical Fundamentals Flame Arresters Master Types Flame arresters are subdivided into different types depending upon the combustion process (Endurance burning, Deflagration, Detonation and the various sub-groups) and in accordance to the installation (in-line, end-of-line, in equipment). energy dissipation into the boundary layer Master types are flame front a) static dry flame arresters b) static liquid seal flame arresters c) dynamic flame arresters Working principle a) Static dry flame arresters energy dissipation into the boundary layer Flame arrester elements made of wound corrugated...

Flame arresters (Fig. 8a) are devices that are installed at the opening of an enclosure or to the connecting pipe of a system of enclosures and whose intended function is to allow flow but prevent the transmission of flame. The PROTEGO® flame arrester unit (Fig. 8b and 7b) is that part of a flame arrester whose main task is to prevent the transmission of flames. 3. Several FLAMEFILTER® (Fig. 7a) form the PROTEGO® flame arrester unit (Fig. 7b and 8b) together with the spacers and enclosing cage. 4. Deflagration flame arresters or detonation flame arresters are required depending on...

Please refer to more specific literature (especially technical information concerning safety ratings) for the MESG of individual substances, additional ratings and characteristic substance quantities. This information is provided by PROTEGO® upon special request. As the pressure and temperature increase, the load on the flame arresters generally increases. Flame arresters that have been tested under standard conditions are approved and can be used up to 60°C (140°F) and 1.1 bar (15.9 psi). If the operating temperature and/or the operating pressure is higher, the flame arrester must undergo...

Technical Fundamentals Pressure and Vacuum Relief Valves Valve Technology Closed vessels or tanks filled with liquid products must have an opening through which the accumulated pressure can be released so that the vessel does not explode. Along the same lines, a vacuum has to be compensated for when the tank or vessel is drained so that it does not implode. Unallowable overpressure and negative overpressure will accumulate with loading and unloading procedure, steam cleaning processes, blanketing and thermal effects. Free openings enable a free exchange with the atmosphere or with connected...

Technical Fundamentals Pressure and Vacuum Relief Valves The sealing between valve pallet and valve seat is provided by an FEP air cushion seal, a metal to metal sealing, or PTFE flat sealing depending on the set pressure or on the application. The best sealing is obtained with a metal valve disc lapped to be seated on the metal valve seat (metal to metal). When the set pressures are low, an FEP air cushion seal provides a tight seal. The tightness of the PROTEGO® valves is far above the normal standard (API2000 resp. EN ISO 28300) and hence meets the stringent demands of emission control...
