ABSTRACT:
A cleaning apparatus for a gas filter may include a movable support, a plurality of orifices, and a control system. The orifices may be arranged on the support for selective discharge of cleaning gas toward corresponding ones of filter openings disposed in a segment of a partition in the gas filter when the support is proximate that segment. The orifices may be grouped into at least first and second groups of orifices that may be fluidly connected to first and second valves configured for selective delivery of cleaning gas The control system may be configured to activate the first valve to cause a discharge of cleaning gas from the first group of orifices when the support is proximate a first segment and to activate the second valve to cause a discharge of cleaning gas from the second group of orifices when the support is proximate a second segment.
