Performance of fabric filters on cyclone fired boilers

Operation of reverse air fabric filters on Baltimore Gas and Electric's C. P. Crane Units 1 and 2 cyclone boilers is documented. Beginning immediately after startup, tubesheet pressure drop increased to high levels. Following stabilization with sonic horns and spare reverse air fans, an investigation was mounted. Diagnostic tools included both laboratory and slipstream pilot baghouses to determine cause and evaluate candidate methods of reduting pressure drop. Fundamental ash properties determined through laboratory pilot testing were in conformance with predictions. Alternate fabrics and coatings did not eliminate the problem. The root cause of the problem was that the amount of variable cake, i.e. that ash removed during cleaning, plays an important role in the dynamics of bag cleansing. These dynamics were absent in the C. P. Crane filters. Confirmation was obtained in the full scale baghouse through modification of the variable cake weight using ash reinjection. Finally, offsetting pressure drop and power consumption reductions have been obtained to achieve satisfactory operation of the baghouses.
