A survey of the literature on performance models for pulse-cleaned fabric filters is presented. Each model is evaluated for its ability to predict average pressure drop from pilot plant data. The best model is chosen and used in conjunction with pressure drop reduction data from an electrostatically stimulated fabric filter (ESFF) pilot plant to produce a model of ESFF performance. The accuracy of the models is limited by their primitive nature and the size of the pulse-jet performance data base. Where the baghouse, dust, and fabric to be modeled are very similar to the pilot plant from which the model was developed, the model should perform adequately for comparison between ESFF and non-ESFF baghouses. Published correlations relating equipment size and cost are used in a model for predicting the capital and operating costs of conventional pulse-jet bag- houses. A comparison between predict- ed capital costs and independently obtained estimates shows that the baghouse cost model is capable of «20% accuracy. A prototype design for ESFF hardware is developed and cost quotes from vendors are incorporated into a predictive equation for ESFF costs. Because there are no pulse-jet ESFF baghouses, the prototype design is subject to revision. This lack of certainty in the hardware design restricts the accuracy of ESFF cost predictions to « 30%. The cost model is best used in comparing cost estimate of ESFF and non-ESFF pulse-jet baghouses and in comparisons of different sizes of conventional pulse-jet baghouses. The performance and cost models are incorporated into a computer program for two different computers: the Tektronix series 4050 computers and the TRS-80 Model 1, III, and 4 microcom-puters. The program requires pulse-jet design data as input and predicts average pressure drop, capital cost, operating cost, and net present value. Complete program documentation is also included.
