  • Energy balance and cogeneration for a cement plant

    Apr 01, 2002· The cement industry is an energy intensive industry consuming about 4 GJ per tonne of cement produced. A thermodynamic analysis for cogeneration using the waste heat streams is not easily available. Data from a working 1 Mt per annum plant in India is used to obtain an energy balance for the system and a Sankey diagram is drawn.(PDF) Energy Balance and Cogeneration for a Cement Plant,This paper builds up an energy balance for an operating plant and estimates the power that can be generated from the waste heat streams. The process of manufacture of cement can be divided into three basic steps, preparation of raw materials, pyroprocessing to produce clinker, and grinding and blending clinker with other prod- ucts to make cement.
