Portland Cement Manufacturing Industry National Emission

Portland Cement Manufacturing Industry National Emission

The kiln is a large furnace that is fueled by coal, oil, gas, coke and/or various waste materials. The product (called clinker) from the kiln is cooled, ground, and then mixed with a small amount of gypsum to produce portland cement. The main source of air toxics emissions from a portland cement plant is the kiln.
