The paper gives results of an evaluation of the ability of the GCA/EPA fabric filter design model to predict pressure drop, penetration, and dynamics of full-scale baghouses. Model predictions are compared with data measured at the Kramer Station of the Nebraska Public Power District. Two values of specific resistance coefficient (K sub 2) and effective residual drag (S sub E) are used in modeling the Kramer baghouse. The field-measured value of K sub 2, combined with the laboratory-measured value of S sub E, produces the best predictions of pressure-drop performance, but the field data exhibit fluctuations that cannot be accounted for by the model. The model overpredicts penetration just after a compartment has been cleaned; but, as the dust cake on the filter grows, the discrepancy between predicted and measured values diminishes.
