Description:
The chapter discusses the use of technologies for reducing air pollution emissions from stationary sources, with emphasis on the control of combustion gen-erated air pollution. Major stationary sources include utility power boilers, industrial boilers and heaters, metal smelting and processing plants, and chemical and other manufacturing plants. Pollutants of primary concern are those that, in sufficient ambient concentrations, adversely impact human health and/or the quality of the environment. Given the wide variety of sources and pollutants, it is no surprise that there is a correspondingly wide variety of approaches to air pollution control. The three primary approaches are pre-process control, process modification, and post-process control. Early work in the field of air pollution control technology focused on sulfur dioxide, nitrogen oxides, and particulates. Control technologies for these pollutants have been refined and tested extensively in service, and have in most cases reached the status of mature technologies. Nevertheless, work continues to improve performance as measured by pollutant reduction efficiency and operating and maintenance cost. These mature technologies are also being evaluated for their performance as control devices for hazardous air pollutants, and as the bases for new hybrid technologies that seek to reduce pollutant emissions by 90% or more.
