“…If we look at the energy‐efficiency trends in cement manufacturing, the recommendations made by the United State environmental protection agency (EPA) play a key role . These recommendations focus on regular maintenance, time to time replacement of machines/components, regular energy audit, usages of improved control and process automation technologies, optimization of fuel mix, optimization of power consumption, condition monitoring, proper load management and load shedding, power quality improvement etc . Looking at the trends and approaches followed till now, two conclusions can be drawn.…”

Energy consumption is increasing day by day and so greenhouse gas emissions. Heavy industries, which consume almost 50% of total energy produced, there is a strong need to implement energy efficiency measures. The electric motor driven systems (EMDS) such as fans, blowers, ventilators, pumps, and compressors are widely used in industries and consume 80% of total industrial electricity. A huge electrical energy saving potential exists with these applications since they frequently come under partial load condition. The optimal flux operation of motors provides significant savings in such conditions, especially in the steady‐state. There are two methods, namely, loss model control (LMC) and search control (SC) used for finding an optimal flux value. In this paper, a case study has been performed to analyze the efficiency improvement of motors of an industrial unit by utilizing superior features of LMC and SC techniques together in a novel way. A total of 65 EMDS are being considered as energy‐efficiency load points for the detailed investigation of a typical integrated cement‐manufacturing unit, located at Durg district, C.G., India. The efficiency improvement validation has been carried out on the MATLAB platform. Significant savings of $2.19 million per annum in energy expenditures, 48,899 tons less per annum of combusted coal and nearly 50,366 tons less greenhouse emissions are estimated at 1 yr. The projected energy use will be in line with “good practice” benchmarks for the sector as well help in “carbon emission reduction target” of state and country. © 2018 American Institute of Chemical Engineers Environ Prog, 38: 672–679, 2019

In this research, we assessed the influence of an ultrafine 2CaO·SiO2 powder on the hydration properties of a reactive powder concrete system. The ultrafine powder was manufactured through chemical combustion method. The morphology of ultrafine powder and the development of hydration products in the cement paste prepared with ultrafine powder were investigated by scanning electron microscopy (SEM), mineralogical composition were determined by X-ray diffraction, while the heat release characteristics up to the age of 3 days were investigated by calorimetry. Moreover, the properties of cementitious system in fresh and hardened state (setting time, drying shrinkage, and compressive strength) with 5% ordinary Portland cement replaced by ultrafine powder were evaluated. From SEM micrographs, the particle size of ultrafine powder was found to be up to several hundred nanometers. The hydration product started formulating at the age of 3 days due to slow reacting nature of belitic 2CaO·SiO2. The initial and final setting times were prolonged and no significant difference in drying shrinkage was observed when 5% ordinary Portland cement was replaced by ultrafine powder. Moreover, in comparison to control reactive powder concrete, the reactive powder concrete containing ultrafine powder showed improvement in compressive strength at and above 7 days of testing. Based on above, it can be concluded that the manufactured ultrafine 2CaO·SiO2 powder has the potential to improve the performance of a reactive powder cementitious system.
