How do you test a spark arrestor?

Spark arresters are tested for their effectiveness by introducing special carbon particles (simulated sparks) while air (simulated exhaust gas) is flowing through the device. The effectiveness is quantified simply by the ratio of particles trapped or pulverized by the arrester to those introduced during the test.

How do flame arrestors 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.
