FIGURE 7.14 A fabric filter (baghouse).
Fabric filters are frequently used in spray dry absorption (SDA) systems to con-
trol acid gases and particulate matter. As shown in Figure 7.15, a lime slurry is
sprayed into the flue gas stream to cool the gas and disperse the lime into the gas
stream. The lime reacts with acidic pollutants in the gas phase and is collected on the
surface of the bags in the baghouse. This forms an absorptive filter which provides
