Flashback Guards & Spark Arresters

A conventional flame arrester is not usually a cost-effective way of protecting air intakes or fuel/air intakes on larger burners and oxidizers from the risk of flashback into flammable atmospheres. Flashback guards are normally used for these duties. Spark arresters behave as filters to remove incandescent particles from the process gas stream.

Since production began over 50 years ago, Elmac Technologies has developed a range of 304L and 316L Stainless Steel knitted mesh panels which perform the functions of flashback guards and spark arresters. Products are available custom-designed in both rectangular and circular shapes, and depending on size, can be provided as single or modular units.

Applications

Flashback guards and spark arresters are used in a wide variety of applications to prevent the passage of incandescent particles (sparks) from one part of a plant/system/process to another.

Principle of Operation

A knitted mesh panel placed in an air stream allows a continous flow of air, but restricts the passage of particles (including sparks).

Benefits

• Corrosion-resistant stainless steel materials
• Single-piece or modular designs
• Sizes to order, available in 1mm increments
• Frames and mountings tailored to customer requirements
