Abstract:

Cement industry is known to be an energy-intensive, one which consumes considerable amount of energy during the production process. In the present industrial scenario, importance is given to the energy-intensive sectors, in terms of use of energy and energy conversion efficiency. The present investigation concentrates on energy conversion and optimization of operational parameters of a cement industry, with respect to the factors such as increased competition, costs, reduced profit margin, impact on environment etc. To find a viable alternate to these factors, a study on the electrical and thermal energy analysis was carried out in a cement plant with a capacity of 1500 tonnes per day. The conservation of energy could be made in three effective ways, such as effective use of electrical equipment, effective and change in operation of existing operational equipment without investment, change of existing equipment with the state-of-the-art equipment with investment. Ten years of operational data of Specific Energy Consumption (SEC) of equipments of the industry is collected and analysed for this study. From the energy study, the Energy Conservation Opportunities (ECO) amounting to net saving of SEC 14kWh per ton of clinker (11.6%) is identified. On successful implementation of suggestions that the 9.5 kWh per ton of clinker is realised without major investment and 4.6 kWh per ton of clinker with investment with a payback period of less than 2 years. The possibility of thermal energy saving upto 1000 kJ per kg of clinker is also identified by this study.
