Abstract

A system for reducing the occurrence of fires in a fabric filter dust collection system. The system includes an elongated housing having a first end and a second end distal from the first end. A gas flow inlet is provided 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 is provided in flow communication with the housing for flow of gas and particulates out of the housing and into the dust collection system. An elongated spark arrestor is disposed in the housing between the first end and the second end. The spark arrestor has a plurality of spaced-apart, wedge-shaped members having a gap between adjacent members sufficient to interrupt the flow of combustible particles from the source to the dust collection system.
