Utilization of Waste Heat Recovery in Jordan Cement Factories

Abstract

This research aims to investigate the potential of using the exhaust gases generated through the cement industry, to reduce the electricity consumption rate of the grid in the cement factory using a suggested design of thermodynamic cycle, which will lead to an improvement of the overall energy efficiency in the plant. Results showed that simple Rankine cycle came up to have the highest efficiency which is equal to 21 % and the most suitable cycle to cement factories with production capacity equal to 3500 ton/day of clinker or more where the temperature range of the cooler exhaust gases is (300-420) ˚C.
