Flame arrestor plate

Heat transfer effect (cooling effect)
When the flame attempts to pass through the dense tiny channels on the flame arrestor plate, it will be divided into many small flame streams. Youdaoplaceholder0 12 this greatly increases the contact area between the flame and the channel wall, thereby enhancing heat transfer. The channel walls (usually made of metal) will rapidly absorb the heat of the flame, causing the temperature of the flame to drop sharply. When the temperature drops below the ignition point of the combustible material, the combustion reaction cannot be sustained and the flame is extinguished.

Wall effect (quenching effect) ‌
Combustion is a chain reaction involving free radicals. When flammable gases burn in the narrow channels of the flame arrestor, the probability of free radicals colliding with the channel walls will increase significantly. Youdaoplaceholder0 These collisions consume the energy of free radicals, resulting in a sharp reduction in the number of free radicals participating in the combustion reaction. When the channel is narrowed to a certain extent, the free radicals are inactivated by colliding with the vessel wall almost before reacting with other combustible molecules, and the chain reaction cannot spread further, thus preventing the flame from spreading to the unburned gas area.

In simple terms, a flame arrestor is like a precise "flame filter". It protects the safety of pipelines, storage tanks and other equipment by means of ‌ physical methods ‌, taking advantage of the cooling effect of the ‌ channel wall ‌ and the interference of ‌ with the combustion chain reaction ‌, providing a dual guarantee to prevent the spread of flames.
