What is inline flame arrestor?
Inline deflagration flame arrester designed to prevent the transmission of a deflagration (explosion propagating at subsonic velocity). Inline flame arresters are fitted with two pipe connections, one on each side of the flame arrester.
Where do you put a flame arrestor?
Flame arrestors should be installed within 5 ft but not more than 10 ft from the point of discharge. The most likely source of ignition will be a compressor, lightning, or flame at a pipe outlet. Flame velocity increases with distance and with obstacles such as T’s and bends.
How does a flame arrestor work?
A flame arrester functions by absorbing the heat from a flame front traveling at subsonic velocities, thus dropping the burning gas/air mixture below its auto-ignition temperature; consequently, the flame cannot survive. The heat is absorbed through channels (passages) designed into an element.
What is difference between NRV and flashback arrestor?
A flashback arrestor should not be confused with a non-return valve, which has no particular flame stopping properties. A non-return valve can reduce the probability of a flashback, as it serves to prevent reverse flow of oxygen into fuel lines and fuel into oxygen lines.
Does propane detonate or deflagrate?
Detonation of the propane-air mixture in the tube was initiated by explosion of an explosive charge placed at the tube end. Detonation occurred in the propane–air cloud bounded on one side by a rigid vertical wall, and no detonation was observed in the cloud with similar injection of hot products without a rigid wall.
Can a propane tank explode if too cold?
Always store your propane tank outdoors at least five feet away from your home – never bring it inside for the winter as it has the potential to explode at warmer-than-normal temperatures (and there’s always that one family member who wants to crank the thermostat to keep warm…)
Why do LPG tanks explode?
Firstly, a gas leak from the cylinder or regulator gets mixed with air, forming a combustible mixture. To complete the fire triangle we need a spark or a source of ignition. This spark ignites the combustible LPG-air mixture and this leads to an explosion.
Where are flashback arrestors required?
Placement of flashback arrestors In line with WorkSafe recommendations, flashback arrestors should be fitted at each gas line at the regulator outlet for hoses less than 3m long. For hoses longer than 3m, an additional flashback arrestor is needed at the torch end.
