Industrial energy consumption lies between 30% and 70% of the total energy consumed in selected countries. Cement production is one of the most energy intensive industries all around the world. This paper deals with an energy audit analysis in a cement plant different strategies are offered to reduce energy losses. Generally,
This energy saving would result in a considerable reduction of fuel consumption (almost 12%) of the kiln system, and the overall system efficiency would increase by approximately 5–6%. 4. Conclusions. A detailed energy audit analysis, which can be directly applied to any dry kiln system, has been made for a specific key cement plant.
