Nippon Steel Engineering has completed construction of one coke dry quenching plant with maximum coke throughput of 80 tonnes per hour at JFE Steel’s East Japan Works in Chiba in Japan and has handed over the plant to JFE which has been started up and is now under operation. The Plant is designed to be environmentally friendly by minimizing dust emissions during coke conveying and cooling process to make it suitable for an urban steelworks. The plant cools red hot coke of approximately 1,000 degree Celsius, which is carbonized in a coke oven using inert gas within the cooling chamber and recovers sensible heat of red hot coke as steam in the waste heat recovery boiler where previously the sensible heat was diffused. Electricity generated by CDQ is environmentally friendly and clean energy. In comparison with conventional wet quenching plants, it is superior in three ways1. Less dust generation when cooling coke2. Less CO2 emissions through power generation by steam3. Higher quality coke suitable for use in blast furnaces. Although the project was implemented under various restrictions due to the COVID-19 pandemic, Nippon Steel Engineering avoided progress delays by revising our supply chain and establishing a remote manufacturing management system, which ended-up in achieving a smooth startup of the CDQ plant ahead of schedule. Nippon Steel operates CDQ businesses not only in Japan but also internationally, such as in China, South Korea, Taiwan, Vietnam & India etc. The completion of this construction brings the total number of CDQ delivered by our group to 154 plants. All of the CDQ supplied have achieved high rates of operation and highly efficient power generation, being complimented from customers in Japan and international markets for their technical advantages and reliability which is backed by extensive track records as aforesaid, and project management capabilities that enable us to ensure the startup of plants on schedule.
