Standards for Energy Consumption in the Cement Industry in Iran
Iranian Fuel Conservation Company (IFCO) along with the Power Ministry in Iran has set energy consumption standards for different industries. For the cement industry, the standard is set for the Ordinary Portland Cement (OPC) with the fineness of 2800 cm2/g. The standard specifies the electricity and fuel intensity for different types of cement production processes, as following:
