MELTING The glass melting operation is the largest source of emissions for the glass manufacturing industry, and consequently, most efforts in this research program have been directed toward measuring the emission rates of various criteria pollutants that are produced from this high-temperature process.
The U.S. cement industry is made up of either portland cement plants that produce clinker and grind it to make finished cement, or clinker-grinding plants that intergrind clinker obtained elsewhere, with various additives. Clinker is produced through a controlled high-temperature burn in a kiln of a measured
