Fabric Filter Design Variables

Baghouses are designed by considering a number of variables: pressure drop, filter drag, air-to-cloth ratio, and collection efficiency. Although rarely done because it may not be possible or practical, it is a good idea to use a pilot-scale baghouse during the initial stages of the baghouse design. However, previous vendor experience with the same or similar process to be controlled will generally be adequate for design purposes. Careful design will reduce the number of operating problems and possible air pollution violations.
