Nowadays, Coke Dry Quenching (CDQ) plant has been regarded as essential facility as a counter-measure against environmental problems like global warming by CO2 and air pollution. CDQ has widely spread especially in Asia. Because one large CDQ (single-chamber CDQ) is more efficient than multiple small CDQ (multi-chamber CDQ) and this fact generates much benefit for the users, currently, almost all users choose single-chamber CDQ. In order to cope with a tendency of recent enlargement of coke ovens, expansion of single-chamber CDQ capacity was necessary. NIPPON STEEL & SUMIKIN ENGINEERING CO., LTD. (NSENGI) has the best single-chamber CDQ solutions. Since 1976, NSENGI has constructed the first CDQ plant with 56t/h capacity in Yawata Works of NIPPON STEEL & SUMITOMO METAL CORPORATION; NSENGI has not only left a lot of construction achievements but also expanded this technology to other countries, especially in other Asia countries. In addition, through the long-years development of CDQ technologies, we have established numerous original technologies. Now, NSENGI has developed world’s largest 280t/h capacity single-chamber CDQ and is one and only supplier which can supply CDQ with various capacity from 56t/h to 280t/h, which is most suitable for each customer. In addition, “Stable operation” is very important factor to single-chamber CDQ.
