Abstract :

The increasing rate of energy consumption and limitation of fossilized sources which are the main sources ofenergy in Iran and the world has made the industrial societies to seek for providing their essential energy fornow and future. More than 26% of total energy is used in industrial section. Cement section is one of theimportant sub-sections of industry which is greatly energy-dependand, so that more than 15% of the energyallocated to industry is consumed in sub-section. Considering the “targeted subsidy plan” and “energy priceliberalization”, the current rate of energy consumption in cement industry needs to be seriously revised.Production management, changing the ingredients of cement, finding alternative ways for replacing energy, andimporting new technology can have good results in reducing energy consumption in cement industry. In thispaper, energy consumption in its electrical and heat forms in a cement factory is investigated. The different waysfor reducing energy consumption were also investigated in this paper. Findings of different studies carried out bythe research units involved in cement industry in recent years indicate changes in production methods with anemphasis on energy consumption reduction and production increase. These changes include replacing wetmethod by dry method or development of pre-heating center. Nowadays, in cement industry, not only there is anemphasis on decreasing energy consumption to decrease the production costs, but also the environmental factorsare focused. Over 0.7 kg of CO2 and other pollutants is released into the invironment as per production of 1 kcement particles. Therefore, application of alternative fuels which contain less carbon in their structural formulawill result in reduction of both consumption and production cost as well as fewer pollutants released into theenviroment
