Abstract:
1. A system for reducing the occurrence of fires in a fabric filter dust collection system, comprising: a source of emissions, the emissions comprising spark particles; an elongated housing having a first end and a second end distal from the first end; a gas flow inlet in flow communication with an interior portion of the housing for flow of gas and particulates from a source into the housing; a gas flow outlet in flow communication with the housing for flow of gas and particulates out of the housing and into the dust collection system; and an elongated spark arrestor disposed in the housing between the first end and the second end, the spark arrestor comprising a plurality of spaced-apart, wedge-shaped members having a minimum gap and a maximum gap between adjacent members sufficient to substantially interrupt the flow of spark particles from the source to the dust collection system, wherein the maximum gap is wider than the minimum gap.
