Investigation of energy saving and NOx reduction possibilities in a rotary cement kiln

In this study, the possibilities of energy saving and NOx reduction achievable by operational changes in a rotary cement kiln system have been investigated. Basic input data were obtained from the field measurements. Analysis has been carried out considering the energy balance and reaction kinetic calculations. Simply controlling the operational parameters, the options of 7.5% energy saving and 15% NOx reduction have been obtained. Copyright (C) 2003 John Wiley Sons, Ltd.
