On October 30, the company’s 800,000-ton heat recovery coke oven project, equipped with a Coke Dry Quenching (CDQ) system, was successfully completed and put into operation. This marks another major step forward for the company in the fields of energy conservation, environmental protection, and intelligent manufacturing. The successful commissioning of the system not only further improves the company’s coking process chain but also injects new momentum into the development of a green and efficient production system.

The CDQ system adopts an inert gas circulation cooling process, in which hot coke is cooled in a fully enclosed environment instead of by traditional wet quenching. This represents a green leap from “heat dissipation” to “heat recovery.” The process effectively eliminates dust and wastewater emissions while efficiently converting high-temperature sensible heat into usable steam energy. Through this, a closed “coke cooling–energy recovery–steam generation” cycle is formed, achieving genuine waste-heat power generation and energy recycling.

The system is designed with a processing capacity of 100 tons per hour and is equipped with a natural circulation CDQ boiler. According to design estimates, it can recover approximately 120 million kWh of electricity annually, equivalent to saving about 40,000 tons of standard coal and reducing carbon dioxide emissions by over 100,000 tons each year—providing strong support for the company’s progress toward its carbon reduction goals.

The successful commissioning of the CDQ system demonstrates the company’s steady progress on the path toward intelligent manufacturing and green development. Looking ahead, the company will continue to drive innovation, enhance energy efficiency, and contribute to the sustainable development of Malaysia’s steel industry.
