Coal Combustion In Cement Production

  • Oxygen combustion in cement production

    Oxygen combustion in cement production

    Clinker production in atmospheres dominated by CO 2 Oxygen combustion appears to be a promising choice for the cement industry but brings its own challenges. In oxyfuel systems, exhaust gas is returned to the burning zone to compensate for the lost thermal ballast provided by the nitrogen in air.
