ABSTRACT

In this article, after a short description of the general characteristics of fabric filters, the methods to evaluate pressure drop found in the literature are briefly surveyed. To provide a contribution toward a more detailed characterization of fabric filter performance, a one-dimensional time-dependent mathematical model has been developed for both inside−outside and outside−inside gas flow in the bag. Direction of the gas flow in the bag is representative of fabric filter cleaning methods (i.e., shaker, reverse-air, pulse-jet). The resulting simulation model allows for a fairly precise estimation of pressure, velocity, and dust cake fields inside the filter, supported by comparisons with experimental data. Using this simulation tool, the baghouse system design based on economic optimization may be pursued. With this in mind, a mapping example of main operational parameters is presented with the aim of highlighting the capabilities of the proposed methodological approach.
