With the advent of the rotary kiln, it was necessary to develop sophisticated means of preparing the fuel and injecting it into the kiln system.

Sep 08, 2016· The cement kiln therefore is a natural incinerator that has a safe thermal environment for the use of alternative fuels. Use of alternative fuels in the cement kilns hence helps resolve air pollution problems by eliminating additional emissions which would have resulted from the incinerators while destroying the wastes.

Cement manufacturing is the source of 5% of global CO2 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 to 1500°C. Therefore emissions monitoring is extremely critical for cement plants to meet regulatory requirements.
