Energy balance and cogeneration for a cement plant

2002-4-1  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.

Energy auditing in cement industry: A case study

2021-8-11  Industrial energy consumption lies between 30% and 70% of total energy consumed in selected countries [1-8]. A notable amount of energy is used in the cement industry. Therefore, considerable attention is needed for the reduction of energy and energy-related environmental emissions, locally or globally [9-13]. It is reported that this industry consumes about 15% of total energy

MATERIAL AND ENERGY BALANCE knowledgeplatform.in

2017-3-15  Material and energy balances are very important in an industry. Material balances are fundamental to the control of processing, particularly in the control of yields of the products. The first material balances are determined in the exploratory stages of a new process, improved during pilot plant experiments when the process is being planned and tested, checked out when the plant is commissioned and then refined and maintained as a control instrument as production continues. When any changes occur in the process, the material balances
