Protego | Flame Arresters - End Of Line Deflagration
- Flame Arresters are designed to allow the flow of gases, liquids, etc. and to prevent flame transmission.
PROTEGO® Flame Arresters are composed of individual FLAMEFILTER® (flame arrester discs), spacers, and a casing. The FLAMEFILTER® is made of wound, corrugated metal strips. The principle of flame quenching in small gaps is applied in PROTEGO® end-of-line flame arresters and PROTEGO® in-line flame arresters.
When a mixture ignites in a gap between two walls, the flame spreads towards the non-combusted mixture. The expansion in volume of the combusted mixture pre-compresses the non-combusted mixture and accelerates the flame. By heat dissipation in the boundary layer “s”, transferring it to the large surface of the gap length compared to the gap width “D”, and by cooling down the product below its ignition temperature, the flame is extinguished.
The gap width and the gap length of the flame arrester disc determines its extinguishing ability. The narrower and longer the gap, the greater the extinguishing effectiveness. The wider and shorter the gap, the lower the pressure loss. Experiments can determine the optimum solution between the two conditions.
- Model: BE/AD
Features:
• Weather hood provides protection against environmental impact (harsh weather conditions, bird nests, etc.)
• cost effective device

• quick removal of FLAMEFILTER
• available with threaded connection
• provides protection against atmospheric deflagration
• low operating and lifecycle cost
The PROTEGO® BE/AD end-of-line deflagration flame arrester provides protection against atmospheric deflagrations. The device is typically installed on vent lines of small vessels and plants which are not pressurised. For safe application it is important that an endurance burning situation can be excluded, so typically it is installed on vents lines which discharge vapour for a short time period only. The device prevents flame transmission from atmospheric deflagration into the vessel or plant.

Deflagration flame arrester, short time burning proof, end-of-line
Model: LH/AD-T
Features:
• weather hood provides protection against environmental impact (harsh weather conditions, bird nests, etc.)
• cost effective device
• available in sizes DN 50 (2“) – up to DN 800 (32“)
• easy maintenance
• cost effective spare parts
• available for elevated operating temperatures
• protection against short time burning and atmospheric deflagration
• low operating and lifecycle cost
The PROTEGO LH/AD-T end-of-line deflagration flame arrester provides protection against atmospheric deflagration and short time burning on the flame arrester element. The device is typically installed on vent lines of vessels and plants which are not pressurised. The device is equipped with a temperature sensor which immediately detects a flame on the FLAMEFILTER surface. After the flame is detected, a secondary measure, such as inserting or closing of a shut-off valve to block the vapour flow to the device, should activate within 60 seconds and extinguish the flame, so that the plant can operate safely. The device prevents flame transmission from short time burning and atmospheric deflagration into the vessel or plant.

I took a gamble on this sweater, amazon clothing seems to sometimes be way different quality than what’s pictured but I was very happy when I received this sweater!

his sweater is a bulky, fairly heavy winter sweater that will be awesome for the office or casual wear. The fabric is very silky soft. It’s nice and snuggly! I can’t wait for it to get cool enough to wear it!
