Pulse-jet fabric filters for coal-fired utility and industrial boilers: Final report
Pulse-jet fabric filters rely on the filtration of dirty flue gas by the outside surface of the bags, which are then cleaned by a shock wave from an air pulse entering each bag from the top. The shock wave travels down each bag, flexing the bag and dislodging dustcake as it travels the length of the bag downward and then upward. A venturi may or may not be used to enhance the pulse, and cleaning may be on-line or off-line. This study provides a convenient and versatile information base about pulse-jet fabric filters on coal-fired boilers. Features include an overview of the pulse-jet concept, a discussion of the advantages and disadvantages of pulse-jet cleaning, a survey of vendors and design and hardware features of pulse-jet installations, discussion of these design and hardware characteristics for several vendors, case histories of a wide variety of installations as examples, and a list of pertinent references. The most important part of the study is an exhaustive table of pulse-jet installations and their features, sorted several different ways for accessibility. Predominant features of the installations in the list are analyzed and presented in graphic form.
