    Dec 01, 2006· When the energy consumption in this cement plant is examined by fuel types, the largest fuel types being coal with 57.66%, electricity 14.63%, and petro-coke with 27.72%, respectively, and total energy consumption is about 2.04 PJ in this plant for per year. These three fuels constitute 2.23% of the total energy is consumed in raw mill process. 4.Energy and exergy analyses of a parallel flow, four- stage,Since the cement production is an energy intensive process, the energy economics is particularly of interest in this industry. Therefore, this subject has been of much interest in the last few decades. Recently, Engin et al.
