                    Control of air emissions has become an increasingly important and crucial part of
                    design and operation of incineration facilities. Federal, state, and regional air pollu-
                    tion control boards have imposed increasingly more stringent regulations during the
                    last several decades as environmental awareness has grown. More effective and
                    sophisticated air pollution control (APC) systems have been developed to comply
                    with these regulations.
                        This chapter covers several topics related to APC systems:

                        • Formation of pollutant emissions.
                        • Factors affecting their generation and release.
                        • Technologies and operating modes to control emissions.

                        • Advantages and disadvantages of various systems.
                        • Devices used to monitor emissions.
                        There are three main types of pollutants: solid, liquid, and gaseous.


                    1.0 SOLID AND LIQUID POLLUTANTS

                    1.1 Particulate Matter
                    According to the definition in the U.S. Environmental Protection Agency (U.S. EPA)
                    New Source Performance Standards (NSPS) contained in 40 CFR, Part 60, Subpart A,
                    particulate matter is “any finely divided solid or liquid material, other than uncom-
                    bined water, as measured by the reference methods specified” (1991a).
