In the present scenario of a competitive market in cement, the unpredictable power cuts/power failures by State Electricity Board, the high cost of capti ve power generation due to galloping diesel and furnace oil prices, the scarce availability of good quality coal due to steel and thermal power plants being the priority sectors, it became imperative for our engineers to look for all possible avenues of reducing production costs. Electrical and thermal energy form the major part of the cost of cement production, thermal energy accounting for 22% and electrical energy about 20% of the total. Hence, energy conservation has been accorded the highest priority to bring down the cost of production. Ever since its inception, concerted efforts had been made on a continuous basis by the plant's team of dedicated employees to adapt to the teclmological improvements in this field. Accordingly, a massive
