Co analyser cement kiln

The control of the combustion in cement kiln is an enormous challenge because real time data on the gas concentration of O2 and CO are necessary. In typical cement kilns different fuels with different caloric values are used. Mostly the main kiln burner fuel is

    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

    Cement production also is a key source of CO2 emissions, due in part to the significant reliance on coal and petroleum coke to fuel the kilns for clinker production. Globally, CO2 emissions from cement production were estimated at 829 MMTCO2 in 2000 7, approximately 3.4% of global CO 2 emissions from fossil fuel combustion and cement production
