ABSTRACT
In spite of impressive progress over the last decade, fabric filtration for utility/industrial boiler use faces major problems. Foremost among a list of specific shortcomings is the inability to adequately predict baghouse performance before start-up. Each new installation brings performance surprises--sometimes pleasant but often otherwise. The accumulating experiences of predecessor installations continually narrows the range of uncertainty for new start-ups but the capability of designing and building a fabric filter guaranteed to perform within a predetermined envelope has been shown time and again to be beyond the present start-of-the-art.
