Abstract
The cement industry consumes huge amount of electrical energy than the other sectors. The higher percentage of the energy cost was found in its total cost of production. The available resources and environmental constraints are becoming increasingly severe because of the continuous development in the economy of the country. Therefore, the energy-saving and the reduction in the emission of gases in the cement industries have become one of the choices for the process development. The concept of energy-saving determines the realization of the national goals of energy conservation. Taking the reference of one of the cement industry in India (Emami Cement Ltd, Baloda Bazaar, Chhattisgarh) as the main focus, this paper investigates on the energy-saving by implementing the variable speed drives (VSD) along with the cooling fan and motor across the system. This report also analyses the energy-saving potential of the cement manufacturing industry by assuming some different scenarios. The data analysis show that the electrical energy-saving potential of the cement industry is 53.5% with VSD and 51.89% with the use of light-emitting diode (LED) instead of using metal halide (MH) ultraviolet source. Thus, the improvement in energy efficiency can reduce the emission of the carbon dioxide from fuel, use of electrical energy and consequently it has the potential of reducing the cost of the cement production unit.
