ABSTRACT:
A method of retrofitting a dust collecting apparatus is disclosed which has a plurality of filter bags arranged in a number of rows, and which also has a reverse pulse cleaning system. In accordance with the present invention, selected bags are rendered inactive, and the active and inactive bags are arranged in a predetermined pattern so that the active bags are shielded by the inactive bags from the particulate matter expelled from the active bags of adjacent rows during the reverse pulse cleaning operation. This shielding permits a greater volume of air to be pulsed into the active bags during cleaning, which greatly increases the degree to which the active bags are cleaned.
