A system for reducing the occurrence of fires in a fabric filter dust collection apparatus associated with a coke oven charging process, comprising: 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 elongated housing for flow of gas and particulates from a source comprising a coke oven charger into the elongated housing; a gas flow outlet in flow communication with the elongated housing for flow of gas and particulates out of the elongated housing and into the dust collection system; an elongated spark arrestor disposed in the elongated housing between the first end and the second end, the spark arrestor comprising a plurality of spaced-apart, elongated wedge-shaped members each having widths at bases of the wedge-shapes and heights extending outwardly from the bases; the wedge-shaped members having a minimum gap between adjacent members sufficient to interrupt the flow of spark particles, larger than the minimum gap, from the source comprising a coke oven charger to the dust collection apparatus; the wedge-shaped members being oriented such that the bases face toward the gas flow inlet and the wedge-shapes taper toward the gas flow outlet; and a hood comprising a slot and a canopy for capturing emissions comprising gas, fumes and spark particles emitted from the charging of coke from the source comprising a coke oven charger and directing the emissions comprising gas, fumes and spark particles to the gas flow inlet via the slot, the slot being configured to provide substantially even distribution of emissions comprising gas, fumes and spark particles flow into the gas flow inlet. 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 elongated housing for flow of gas and particulates from a source comprising a coke oven charger into the elongated housing; a gas flow outlet in flow communication with the elongated housing for flow of gas and particulates out of the elongated housing and into the dust collection system; an elongated spark arrestor disposed in the elongated housing between the first end and the second end, the spark arrestor comprising a plurality of spaced-apart, elongated wedge-shaped members each having widths at bases of the wedge-shapes and heights extending outwardly from the bases; the wedge-shaped members having a minimum gap between adjacent members sufficient to interrupt the flow of spark particles, larger than the minimum gap, from the source comprising a coke oven charger to the dust collection apparatus; the wedge-shaped members being oriented such that the bases face toward the gas flow inlet and the wedge-shapes taper toward the gas flow outlet; and a hood comprising a slot and a canopy for capturing emissions comprising gas, fumes and spark particles emitted from the charging of coke from the source comprising a coke oven charger and directing the emissions comprising gas, fumes and spark particles to the gas flow inlet via the slot, the slot being configured to provide substantially even distribution of emissions comprising gas, fumes and spark particles flow into the gas flow inlet.
