Abstract
Fabric filters remove dry particles from a gas stream by passage through a filter medium on which the particles are collected in the form of a cake. The filter cake must then be removed from time to time by some form of cleaning process. The cleaning techniques most commonly used are shaking, reverse flow and reverse pulsing. The dust removal efficiency of fabric filters generally lies in the region of 99 to 99.9%. Operating pressure drops are generally in the region of 750 to 2000 Pa. These good performance characteristics make fabric filters the preferred choice for conventional gas-cleaning problems and since the mid-1960s there has been a rapid increase in the range of processes to which fabric filters have been applied. Unfortunately, the success of such installations is critically dependent on the integrity of the filter medium. By definition this is a fabric and, therefore, flexible. The range of temperatures over which flexible media are available is severely limited, and successful installations at temperatures much above 250°C are unusual.
