The PROTEGO® type TS/… series of hydraulic flame arresters Flame Arresters A flame arrester, deflagration arrester, or flame trap is a device or form of construction that will allow free passage of a gas or gaseous mixture but will interrupt or prevent the passage of flame. are mainly designed to protect process plants which are connected to waste thermal combustion units. Hydraulic flame arresters of the TS/… series are particularly suitable to protect plants which supply heavily contaminated, sticking, polymerizing or even foaming substances into thermal combustion units. Generally, it is necessary to protect the plant against in-line deflagration Deflagration Explosion propagating at subsonic velocity (EN 1127-1:1997). , stable detonation Stable detonation A detonation is stable when it progresses through a confined system without significant variation of velocity and pressure characteristics. , and endurance burning Endurance burning Stabilized burning for an unlimited time. hazards, and consider the plant‘s operating conditions.

Hydraulic flame arresters of series TS/… mainly consist of the immersion tank (1) with exhaust air nozzle and connection nozzles for the sparge pipes, the sparge pipes (2) with elbows and connection flanges as well as the manifolds (3) with connection flanges. To allow measurement of the immersion liquid temperature, the tank (1) has a minimum of one nozzle (5) and, for measuring the temperature of the exhaust gas, there is a minimum of one connection for each exhaust air nozzle (6) for inserting temperature sensors. Additionally, the tank has two nozzles (7, 8) for level measurement, two nozzles (9, 10) for level control, and one nozzle (11) for draining. Inspection glasses (4) are included for inspection of the immersion liquid and gas space.

In PROTEGO® type TS/… hydraulic flame arresters. The flammable mixtures are passed through a water seal Seal A seal prevents or limits unwanted transfer of product from one container to another. Seal is used as superordinate term for all types of sealing elements. with a defined immersion depth. The mixture flow is divided and supplied evenly to the individual sparge pipes. The sparge pipes have small drill holes, which produce defined bubble columns. In case of an ignition in the flowing gas mixture, the flame is prevented from returning into the inlet line. The following parameters have a significant effect on the flame arresting efficiency of the 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. in case of deflagrations, detonations, or short-time burning: • Mixture volume flow • Immersion depth from the water seal‘s surface to the upper edges of the drill holes in the sparge pipes, • Water temperature in the hydraulic flame arrester • Precise drill hole diameter in the sparge pipes due to size, form, and density of the bubbles.

A high accuracy volume flow meter must be installed as an essential technical safety element. It has to guarantee that the maximum allowable volume flow, on which the design of the hydraulic flame arrester has been based, is recorded and limited so that emergency functions are triggered if the exhaust air volumes exceed the safe level. In addition, a minimum flame transmission-proof Flame transmission-proof Characteristic of a device to avoid flashback. immersion height is necessary, i.e. an adequate water level must be guaranteed by suitable measuring equipment Equipment Machines, appliances, fixed or mobile devices, control parts and accessories, and warning and prevention systems, whether separate or combined, intended for the generation, transfer, storage, measurement, control, and conversion of energy, and for the processing of materials, which have their own potential source of ignition and may cause an explosion. . The pressure loss of a hydraulic flame arrester at maximum volume flow results from the inlet and outlet losses of approximately 12 to 18 mbar / 4.8 to 7.2 inch W.C. plus the immersion depth, e.g. 350 mm = 35 mbar / 13.8 In = 14.1 inch W.C., so the total is between 47 and 53 mbar / 18.9 and 21.3 inch W.C.
