ENERGY INTEGRATION IN SPONGE IRON PLANT USING HEAT OF WASTE GAS

Waste gas from the rotary kiln of the sponge iron plant exits at a temperature around 900 C. This gas has a lot of sensible heat and can be used for energy integration. This heat is used for heating water in a boiler. Superheated steam which is produced in the boiler is used to rotate a prime mover like a steam turbine.
