The flame arrester comprises a flow passage in which are disposed a plurality of generally aligned rods such that fluids flowing in the passage must pass between the rods. Rows of rods are used to construct the flame arrester element, ideally closely spaced and these present a natural surface over which air can flow with minimal flow resistance. The rods can be of any size and the gaps between them can be selected to arrest explosions due to different gases or vapours in air. The rod diameter can be altered to withstand different levels of explosion pressure, making it possible to construct both deflagration and detonation flame arresters. If tubes are used these can carry cooling fluid making the arrester more effective at coping with continuous burning. Rods in parallel rows can be offset with respect to the adjacent row. Suitable offset angles can vary.
A flame arrester comprising a flow passage in which is disposed an array of adjacent circular section rods arranged in rows, each row being generally co-aligned and arranged transverse to the flow direction, such that fluids flowing in the passage must pass between the rods and the rods forming the rows are offset relative to rods in adjacent rows thereby to require a circuitous flow path for the fluids.
An assembly of a flame arrester according to any preceding claim with a reducer fitted on at least one side thereof to reduce the size of the flow passage.
