Xiaoyi’s first dry quenching project—the Pengfei Coking Plant’s dry quenching facility—is poised to enter operation, marking the beginning of a new chapter in Pengfei’s pursuit of high‑quality, green development and injecting fresh momentum into Xiaoyi’s environmental protection efforts.

On August 5, the No. 1 dry quenching furnace of the Pengfei Dry Quenching Project entered the warm-air drying phase, and at 16:18 on August 10, it was successfully ignited for furnace drying, marking the project’s entry into the final countdown to commercial operation.

The blazing furnace has kindled the passion of all staff at the command center of the coking dry‑quenching project, while also marking a new starting point on Pengfei’s journey toward green and environmentally friendly operations.

As a key project of the Group, the dry quenching project at Pengfei Coking Plant has been closely watched by the Group since its commencement on June 20, 2019.

Following the project’s launch, the Dry Quenching Coking Project Command Center formulated a detailed construction schedule, meticulously accounting for every stage, adverse weather conditions, and potential delays associated with each coke oven overhaul. Both hardware and software components were advanced in parallel, with each phase seamlessly linked to the next, ensuring a tightly coordinated and highly organized execution.

In the face of this spring’s sudden outbreak, they swiftly adjusted their plans and schedule milestones, adopting a reverse‑engineering approach to work backward—securing days within weeks, weeks within months—and pressing ahead with an unwavering “five‑days‑plus‑two” and “day‑and‑night” work ethic to achieve the goal of commissioning the red coke by August 20.

The central electrical control room for the dry quenching system is the core unit ensuring the normal operation of the entire dry quenching process. At present, the large display screens, the system platform, and the production‑preparation personnel are all in place, and individual equipment commissioning is underway. Soon, remote operation of the dry quenching furnace, boiler, dust‑removal system, and other components will be enabled.

The successful ignition of No. 1 CDQ furnace marks the official transition of the project from the warm-air drying phase to the gas‑firing phase. Once the pre‑storage section of the CDQ furnace is heated from its current temperature of 150°C to approximately 800°C—close to the normal operating temperature for dry quenching—the loading of red coke can commence, and the plant will gradually enter regular dry‑quenching operations.
