Dry Cyclone Optimization

26.1 The Dry Cyclone

Of all the “hardware” available to be applied to air pollution control, the dry cyclone often handles the most particulate and performs that task in the simplest of manner. Dry cyclone collectors are often the first device used in a multi-device gas cleaning train. This means the dry cyclone sees the highest concentration and most often, the highest level of erosion and abrasion. As mentioned in the Dry Cyclone chapter (Chapter 4), the target dust that the dry cyclone must separate from a gas stream may also be “friable” (reduced in size as the dust wears on itself and internal cyclone surfaces). Relying on the fact that solid particulate wants to move along a trajectory (unless that path ...
