Cement and Energy

Acknowledgements The specific heat consumption was reduced from 820 to 780 kcallkg clinker after the completion of the modernisation steps in March 1997. The result of various upgrading efforts carried out in May 1997 have begun to show improvements in plant performance. A recent heat balance depicted the specific heat consumption to be 770 kcal!kg clinker. The suggestions/advice given by Mr. E.H. Larsen of Cement Consultants Ltd. UK Dr. B. Pitchumani of ITT and M/s. S.S. Kothari Associate both of Delhi (India) Shri N.L. Manihar and Mr. D.S . Bhandari at various stages of the modernisation project are thankfully acknowledged. SHREE CEMENT BAGS POWER MINISTRY AWARD FOR ENERGY CONSERVATION T he First Prize for Energy Conservation in cement sector for 1997-98, awarded by the Ministry of Power, Government of India, has been won by Shree Cement Ltd . The award is in recognition of the plant's achieving a specific electrical energy consumption of 83.0 kWh/tonne of cement. It was presented by the Hon ' ble Union Minister of Power, Shri P.R. Kumaramangalam at a function held in New Delhi on 14 December 1998, National Energy Conservation Day. Shri M.K Singhi (left), President, Shree Cement and Shri B.G.

Rayner, President and Chief Operating Officer of Essroc Corpn., an Italcementi Group operating company, made the following observations an alternative fuels : ".............it is good public policy to solve environmental problems whenever possible in the conduct of our business. Part of that philosophy includes the use of alternative fuels. In the case of tires, there's the very real potential for a "win-win" situation. We reduce overall emissions associated with coal while solving a solid waste disposal problem that's associated with discarded tires. We recover the energy in the tires and reduce fossil fuel usage. From a business perspective, we save money. Society wins through reduced environmental impact and cost savings associated with disposing of the tires in other ways. "We also see a role for used oil as an alternate fuel. This captures its energy and solves yet another disposal problem. "Substituting hazardous wastes for coal is another option. While this may create some community concerns, · from a business and environmental perspective, energy recovery from these wastes is an intelligent and practical option. These materials can't be landfi lled, and incineration wastes the energy in them." 12 ..
