Dust emission limits in cement plant

Sep 02, 2021 The main source of air toxics emissions from a portland cement plant is the kiln. Emissions originate from the burning of fuels and heating of feed materials. Air toxics are also emitted from the grinding, cooling, and materials handling steps in the manufacturing process. Pollutants regulated under this rule are particulate matter, organic HAP
