The present study is related to the power plant producing electricity for ALUMINIUM COMPANY OF EGYPT.This power generation system is based on a heat recovery system. It was installed onthe waste gas duct of a coke calcination-rotary hearth furnace.A large amount (15 MW / h) of energy is used for the heating process. This energy is in the form of waste heat generated by the by-products of a coke calcination rotaryheater burner. The combustion of coke releases heat, which is used to heat the process, and to generate combustion products that are discharged from the calcification system. All major industries use heating equipment such as furnaces, ovens, heaters, ovens and dryers. Hot gases are discharged from this equipment, after providing the necessary heat process in the atmosphere through the stacks. Therefore, the company can save up approximately 80 GWatt per year due to the production of electricity using their own power plant depending on waste heat recovery boiler and avoiding the loss sustained by releasing this heat into atmosphere.
