Cement and Energy

effects of poor quality power on plant's energy performance and operations, potential for co-generation of power through waste heat recovery, development of energy efficient equipment and systems, etc. Some of the recent studies include field testing of induction motors efficiency, co– generation of power, development of energy management systems, etc. Interior of the Energy Bus with data processing equipment NCB indicates that the reduction in energy consumption levels was the cumulative result of several measures taken by the industry over the years. NCB study showed that the energy -.. savings achieved by the industry in 1995-96, as compared to 1992-93, were equivalent to Rs.617 million (US $ 17 million approximately). Energy conservation through technological and R&D support Keeping in view the typical problems of Indian cement industry, NCB has been carrying out various R&D studies to help the industry tackle their problems. Some important R&D studies in the area of energy conservation include : use of agricultural and industrial combustible wastes, use of alternative fuels like lignite and natural gas, coal sweetening for quality modulation, etc. The specific needs of individual plants also have been studied by NCB in this conte.?Ct and tailor-made solutions recommended to offset the problems caused by poor quality and erratic supply of coal to the plants. In the area of electrical energy, various studies have been undertaken on load management, Airflow measurement at coolerfan inlet by vane anemometer Conclusions Indian cement industry has responded very favourably and judiciously to the challenge of energy conservation thrown up by the ever increasing prices of energy inputs ~d their steadily falling quality. Various steps taken in this regard include: Energy audit studies, proper operational control and optimisation of processes, adoption of upgraded technologies and energy efficient equipment/systems, and utilisation of alternative fuels. The integrated approach outlined in this article will go a long way in meeting the national and international objective of energy conservation. 7
