2026 National Metallurgical Energy and Environmental Production Technology Conference ▲
The 2026 National Metallurgical Energy and Environmental Production Technology Conference and Steel Industry Green Energy-Saving Low-Carbon Technology Exchange Meeting, hosted by the Chinese Society for Metals, recently opened in Yuncheng, Shanxi Province.
2026 National Metallurgical Energy and Environmental Production Technology Conference ▲
Under the theme of "Innovation for Pollution Reduction, Energy Conservation, and Carbon Reduction; Intelligent Collaboration for Green Economy and Cost Reduction," the conference brought together leading industry experts including Academician Jiang Tao and Academician Zhu Rong to discuss cutting-edge technologies and practical pathways for the green and low-carbon transformation of the steel industry.
As one of the co-organizers, Ningbo Taiji Environmental Protection Equipment Co., Ltd. showcased two core technologies. Zhang Jiancan, Technical Director, delivered a plenary presentation titled "DS Combustion Purification Heat Recovery System — Multi-Pollutant Co-Treatment Technology and Equipment for CO, VOCs, and NOx in Industrial Furnace Flue Gas." Liu Changsheng, Chief Engineer, delivered a parallel-session presentation titled "Steel Slag Desulfurization and Comprehensive Utilization of By-Products." Both presentations comprehensively demonstrated Taiji Environmental Protection's deep expertise and innovative capabilities in industrial flue gas treatment and solid waste recycling.

Plenary Presentation: DS Combustion Purification Heat Recovery System — One System for Co-Treatment of CO, VOCs, and NOx
The presentation systematically introduced the company's independently developed DS Combustion Purification Heat Recovery System across dimensions including technical background, process design, technical characteristics, and engineering practice. The system innovatively integrates simultaneous removal of CO, VOCs, and NOx with heat recovery, achieving emission levels far superior to national standards while generating substantial economic benefits for clients. The shared project cases demonstrated outstanding application results and received widespread attention and high praise from attending leaders, experts, and scholars, reflecting Taiji Environmental Protection's strong capabilities in green and low-carbon metallurgical sintering technologies.
To date, the DS Combustion Purification Heat Recovery System has been deployed in 17 units, of which 1 is under construction and 16 are in normal operation. The system saves 124.78 million Nm³ of natural gas annually and reduces carbon emissions by 74,360 tonnes. At an industrial natural gas price of RMB 3.4 per m³, it saves clients RMB 424 million annually, delivering significant economic and social benefits.
Parallel Session: Steel Slag Desulfurization and By-Product Utilization — Treating Waste with Waste, Building a Regional Circular Economy Model
Liu Changsheng, Chief Engineer of Taiji Environmental Protection, delivering the report ▲
During the conference, Liu Changsheng, Chief Engineer of Taiji Environmental Protection, delivered a presentation titled "Regional Circular Economy — Steel Slag Desulfurization and Comprehensive Utilization of By-Products." The presentation systematically covered the technical principles, economic analysis, regional circular economy model, and engineering applications of steel slag desulfurization and by-product comprehensive utilization. This technology uses steel slag as a desulfurization absorbent to replace limestone, significantly reducing desulfurization costs while achieving coordinated solid waste disposal and carbon reduction. The desulfurization by-products can be widely used in building materials production and saline-alkali land ecological restoration, truly achieving "treating waste with waste to enable resource reuse."
Taiji Environmental Protection's exhibition booth drew large crowds. The technical team patiently addressed every technical detail and provided professional advice tailored to specific application scenarios, making the booth one of the highlights of the conference. Taiji Environmental Protection remains driven by technological innovation, committed to providing enterprise clients with system solutions that achieve both cost reduction and green low-carbon development. Moving forward, the company will continue to collaborate with partners across sectors, empowering green and low-carbon development in more industrial fields through technological innovation.
