Dec 01, 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..
Industrial energy consumption lies between 30% and 70% of the total energy consumed in selected countries. cement production is one of the most energy intensive industries all around the world. this paper deals with an energy audit analysis in a cement plant different strategies are offered to reduce energy losses..
Methods this study follows the principles outlined by the international organization for standardization (iso : and iso :) to conduct lca of the cement industry in myanmar.
Reducing energy demand in all areas must be com-bined with the search for the optimal operating point that is consistent with productivity and quality targets. variable speed drives – an electrical energy saver in the cement manufacturing process large fans draw air through the kiln, precalciner, mills and filters to an ex-haust.
