China Steel Corporation Orders Coke Dry Quenching from NipponSteel

Nippon Steel Engineering Co Ltd has received an order from China Steel Corporation of Taiwan for one of the largest coke dry quenching in the world

Nippon Steel Engineering Co Ltd has received an order from China Steel Corporation of Taiwan for one of the largest coke dry quenching in the world for their Kaohsiung steel mill. This CDQ project, for the replacement of the old coke oven with a new one, features a state-of-the-art technology to meet the latest environmental requirements. In comparison with the wet quenching type with water sprinkling, CDQ improves environmental performance by reducing the generation of dust when cooling the coke, and the recovered steam can be utilized to generate electricity, which also contributes to energy saving and reduction of CO2 emissions.

The coke cooling capacity of the CDQ is the largest in the world is 260 tonnes per hour and is unique to the NSE Group, which has supplied four units in the past. Generally, the uniform cooling of coke inside the cooling chamber becomes more technically challenging as CDQ gets larger, but NSE has conducted long years of research and development via full scale prototypes and simulation analysis for ensuring a uniform flow of cooling gas and coke in order to achieve unique technology that provides stable operation while maintaining cooling efficiency at large scales.

With this order, the NSE Group has received orders for a total of 140 CDQ units over the world, including Japan, China, South Korea, and India.

Looking ahead, NSE will continue to greatly contribute to the protection of the environment and development of the iron and steel industry all over the world as the top supplier of environmental and energy-saving technologies.
