Flameless Explosion Venting
Flameless vents may be installed over explosion vents to extinguish flames while still allowing pressure to escape, making indoor “passive” explosion protection solutions possible.
How Does Flameless Explosion Venting Work?
Flameless Vents’ Effect on Venting Efficiency
An essential performance indicator for an explosion venting system is its venting efficiency, which describes how effectively it relieves pressure in a vessel during a deflagration. Flameless venting systems, however, include flame filters to make indoor venting achievable, but when the flame filter becomes clogged by burnt and unburnt particles, its venting efficiency is reduced.
If this efficiency rating isn’t properly calculated for an application in which flameless vents are installed, they may not safely relieve the deflagration pressure when called upon. For example, a flameless vent may perform very well under 500g/ m3 of cornstarch, showing an efficiency of 70 percent, but clogs very quickly under 500g/m3 of wood flour, showing an efficiency of just 40 percent or lower.
That’s why flameless venting performance cannot be described by one efficiency number but rather must be disclosed through a complex model that considers all of the factors of the process and its handled dust.

Introducing Fike FlamQuench™ III
As your explosion protection partner, you can trust Fike to not only reliably protect your workers from industrial hazards but also to protect your company’s bottom line by providing our most cost-effective solutions without sacrificing safety.
That’s why we’ve developed FlamQuench III SQ, a flameless venting system that offers greater explosion venting efficiency, potentially fewer required devices and improved cost of ownership. This is possible due to the removal of the Particle Retention Screen (PRS), which upon a deflagration improves the flameless vent’s efficiency by decreasing the amount of particulate clogging the flameless device.
FlamQuench III fills an important role by providing new and more cost-effective options when designing your explosion protection system.
FlamQuench III SQ
- Dust particles are released to the outside
- More external hazards (larger safety distance)
- Higher venting efficiencies
- Larger maximum protected volumes (Vmax)
FlamQuench II SQ
- Dust particles are retained inside vessel
- Lower external hazards (smaller safety distance)
- Lower venting efficiencies
- Smaller maximum protected volumes (Vmax)
