Through energy audits, including kiln system performance testing and calculation of mass and heat balances, specific opportunities for improving energy efficiency and lowering CO 2 emissions can be identified. A cement manufacturing energy audit should at a minimum address the energy use and recommend potential actions, such as:
Source of waste heat in cement kiln system. In general 54% of the fuel energy consumption is required for the chemical reaction of the kiln fed to produce clinker. About 16% of the fuel energy consumption is consumed for drying of the raw materials in the raw mill.
Raw materials to the kiln consist of calcium carbonate (CaCO 3), silica (SiO 2), shale (Al 2O 3) and iron oxide (Fe 2O 3) feeds. These compounds are very fine powder and mixed with cement to form [4]. 3. Energy Balance For the balance of power in the rotary kiln, the average temperature of the walls was used in this model. The
