Energy balance and cogeneration for a cement plant,

01/04/2002· 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. It is found that about 35% of the input energy is being lost with the waste heatHeat balance excel sheet - detailed calculations - Page 1 of 8,02/11/2011· Heat balance excel sheet - detailed calculations.
