Investigation of Waste Heat Recovery in Cement Industry: A Case Study

N. A. Madlool, R. Saidur, and N. A. Rahim

Abstract—In recent years, there has been an increasing interest in waste heat recovery in the cement industry. The aim of this work is to determine the waste heat recovery by utilizing the waste exit gases from the pre-heater and grate cooler to generate electricity, furthermore estimation of cost saving. The results based on the operational data which is collected from Al-Muthanna Cement Plant. The net power output of 834.12 kJ/kg was estimated. A 6.673 ×103 MWh/yr electricity generation were achieved. The cost saving was estimated of 467,110.00 USD/yr in addition to 20 months was expected as the simple payback period.

Index Terms—Energy saving, cost saving, pre-heater, cement industry.
