SMS group supports SAIL IISCO in achieving sustainability objectives with advanced Paul Wurth coke dry quenching systems

• Two 130-ton-per-hour, single-chamber coke dry quenching (CDQ) units will facilitate IISCO Burnpur’s steel production expansion to 4.8 million tons of coke per year
• Paul Wurth cokemaking technologies are set to enhance coke quality, production reliability, and operational safety
• Improved sustainability through energy recovery and reduced emissions

SMS group, together with its consortium partner MCK Kutty Engineers Pvt. Ltd., has signed a contract with IISCO Steel Plant (SAIL) in Burnpur, West Bengal, India, for the supply of two coke dry quenching (CDQ) units. Each CDQ has the capacity to process 130 tons of coke per hour for the new stamp charge coke oven batteries no. 13 and 14, which form an essential part of the plant’s crude steel expansion to 4.8 million tons per year.

The project will be delivered on a discrete turnkey basis, including design, engineering, supply, installation, commissioning, electrics and automation, digitalization, and related services.

These two units will be the largest single-chamber CDQs in any of the integrated steel plants SAIL operates. By leveraging the benefits of Paul Wurth cokemaking technologies, the systems will deliver high coke quality, stable cooling performance, and reliable, continuous operation—ensuring consistent, moisture-free metallurgical coke for downstream blast furnace processes.

In addition to operational reliability, the CDQs provide significant environmental benefits, including efficient heat recovery and lower emissions compared to conventional wet quenching. This supports SAIL’s broader sustainability objectives and enhances the plant’s overall energy performance.

SMS fosters a strong partnership with IISCO Burnpur, including an ongoing project for a 6.25-meter-tall Paul Wurth Stamp charge coke oven battery and machinery, awarded in 2025. Under the new CDQ contract, SMS will supply all major technological components—while MCK Kutty Engineers Pvt. Ltd. will support the on-site execution by providing erection activities.

This contract represents a significant step forward for SAIL’s modernization program and solidifies the long-term collaboration between SMS and IISCO Burnpur.

Bernhard Steenken, CSO, APAC & MEA, SMS group, said: “We are honored that SMS group, together with MCK Kutty, has been selected to deliver these advanced CDQ units to IISCO Burnpur. Our Paul Wurth technologies will support improved coke quality, higher energy recovery, and reliable, stable operation. As Sail’s partners, we are proud to support its expansion and sustainability goals.”
