A practical guide to improving cement manufacturing ...

Cement manufacturing is the source of 5% of global CO 2 emissions. 60% of emissions are due to the transformation of raw materials at high temperatures and 40% results from the combustion required to heat the cement kilns 1400°C to1500°C. Therefore emissions monitoring is extremely critical for cement plants to meet regulatory requirements.
