ABSTRACT:
A system for cleaning at least one filter in a baghouse and an associated method for providing the system. The at least one filter separate a dirty gas chamber from a clean gas chamber, and filters at least one substance from a gas. The system includes a supply of compressed air and a blowpipe to direct the air at the at least one filter to dislodge a collected amount of the at least one substance from the at least one filter. The blowpipe has a cross-sectional flow area through which the compressed air flows. A valve controls provision of the compressed air. The valve has a cross-sectional flow area though which the compressed gas flows. The cross-sectional area of the valve is smaller than the cross-sectional area of the blowpipe to provide for air pressure at the valve to be greater than air pressure at the blowpipe.
