Role of Blended Cement in Reducing Energy Consumption
The cement industry has long recognized that the cost of energy can be significant, varying between 25 and 35 % of total direct costs. Consequently, the industry is continuously investigating and adopting more energy-efficient technologies to improve its profitability and competitiveness. In particular, plants have moved steadily away from less energy-efficient wet process kilns toward the more fuel-efficient dry process kilns. The industry has achieved additional energy efficiency gains by using pre heaters and pre calciners. These technologies have helped the industry reduce its energy consumption per tonne of cement by 30 %. Since these processes has attained its maximum outreach, the present study focuses on role of blended cement in reducing energy consumption during the cement manufacturing process. This has been achieved primarily due to adaptation of significant steps which was not being practiced during the production of conventional cement. Firstly as the use of even inferior quality of limestone can be used, it will save huge amount fossil fuels, which otherwise had been used during transportation of superior quality of limestone from large distances. Additionally since the limestone will not undergo through clinkerization, it will save enormous amount of energy. It is also being found that this blended cement uses calcined clay at lower temperature, and hence will be able to save huge amount of energy.
