The waste gases in a rotary kiln typically include carbon dioxide (CO2), nitrogen oxides (NOx), sulfur dioxide (SO2), and volatile organic compounds (VOCs). These gases are generated during the combustion of fuels, such as coal or natural gas, and the release of volatiles from the raw materials being processed in the kiln. The emissions of these waste gases can be controlled and reduced using various pollution control technologies.
Smelting waste is called dross.
