Explanation

SPM is suspended particulate matter which is less than 10 mm remaining in air for more than one day to several weeks. It includes aerosol, dust, mist, smoke, soot etc. In a coal-fired power plant, electrostatic precipitators (ESPs) are commonly installed to control the emission of Suspended Particulate Matter (SPM) or particulate matter in the flue gas. SPM refers to fine ash, dust, and other solid particles that are generated during the combustion of coal. ESPs are effective air pollution control devices designed to capture and remove these airborne particulates before they are released into the atmosphere, helping to reduce the emission of SPM and improve air quality.
