Nippon Steel Engineering and NEDO (New Energy & Industrial Technology Development Organization) successfully finished construction of Coke Dry Quenching (CDQ) equipment at Tata Steel’s iron works in India and the opening ceremony was held at the site on Monday. Indian steel industry including Tata Steel, Ministry of Steel and Ministry of Finance jointly participated in the project.
Indian steel industry required Japanese high technology for energy saving when Indian energy demand is expanding along rapid economic growth. They can utilize exhaust heat from coke production process by CDQ. Nippon Steel Engineering plans to confirm performances of CDQ for energy saving and to appeal CDQ against Indian steel industry and other countries. The project was to install CDQ in the coke plant of Tata steel’s Jamshedpur iron works during fiscal 2006-2011. The iron works shifted to dry method which cools red burning coke by inactive circulating gas from conventional wet method using water. Then exhausted heat can be utilized as steam inside the plant. CDQ can reuse 84% of exhausted heat, which equals to heavy oil saving at 50,000 tonnes per year and contributes to less CO2 emission at about 137,000 tonnes per year.
