Particulate formation and control technologies

Particulate matter (PM) is the general term used for a mixture of solid particles and liquid droplets found in the air. Some particles are large or dark enough to be seen as soot or smoke while others are so small they cannot be seen with the naked eye. In general, airborne particles range in size from 0.001 to 500 μm, with the bulk of the particulate mass in the atmosphere ranging from 0.1 to 10 μm. This chapter discusses and defines the range of particle sizes for various materials and a range of particle sizes for which various types of collection equipment are appropriate. Control technologies relevant to particulate matter from fossil fuel-fired stationary systems is discussed in detail, including ...
