The project “Research and Application of High-Efficiency, Energy-Saving Waste Heat Recovery Technology for Raw Coke Oven Gas in the Rising Pipe,” jointly completed by Jiangsu Longye Energy-Saving Technology Co., Ltd., MCC Coking Refractories (Dalian) Engineering Technology Co., Ltd., Fujian Sangang Minguang Co., Ltd., and Wuhan University of Science and Technology, By the China Iron and Steel Association and the Chinese Society for Metals 、 The Metallurgical Science and Technology Award Review Committee conducted a rigorous evaluation and conferred the award “ 2022 First Prize in Metallurgical Science and Technology, awarded by the China Iron and Steel Association and the Chinese Society for Metals. ”。 The technological achievements of this research have made a significant contribution to energy conservation and emission reduction in the coking industry, holding great significance not only for the coking sector but also for the broader steel industry.

The Metallurgical Science and Technology Award is China Iron and Steel Association 、 Chinese Society for Metals The award, established as the highest science and technology prize in China’s metallurgical industry, recognizes innovative achievements that have made significant contributions to the sector, advanced related disciplines, and earned widespread recognition from peers both at home and abroad.

Since 2010, under the leadership of Chairman Meng Xiaodong, Jiangsu Longye Energy‑Saving Technology Co., Ltd. has undertaken a joint research effort to address the challenges of efficiently, stably, and reliably recovering waste heat from coke oven riser pipes operating under harsh conditions—high temperature, corrosive environments, and cyclic temperature fluctuations. The project team conducted fundamental research, optimization, analysis, and comparative studies on operating conditions, materials, and structural design, successfully overcoming key technical hurdles and developing core technologies that resolve issues such as pipe leakage, tar deposition, and dry‑burning. As a result, the company independently developed an advanced, energy‑efficient waste‑heat recovery technology for coke oven riser pipe raw gas, enabling the successful industrialization, large‑scale deployment, and commercial application of complete waste‑heat recovery systems. This has ensured the safe, environmentally friendly, long‑life, and highly efficient operation of riser equipment and associated systems. Jiangsu Longye Energy‑Saving Technology Co., Ltd. holds 38 authorized patents, including 11 invention patents; in 2018, it participated in drafting the industry standard “Technical Specification for Sensible Heat Recovery and Utilization of Raw Gas in Coke Oven Riser Pipes”; in 2019, it was awarded the First Prize for Metallurgical Science and Technology Progress by Shandong Province; and in 2020, its coke oven riser pipe waste‑heat recovery system featuring nano‑self‑cleaning coated heat exchangers was certified by the China Metallurgical Society as being at an “internationally leading” level.

The waste heat recovery technology for raw coke oven gas in the rising pipe represents a coking‑process solution that aligns with the national “dual carbon” strategic framework; it is a concrete measure for reducing carbon emissions and fully and accurately implementing the new development philosophy; it points to the direction and holds significant potential for coking enterprises to conserve energy, build green coking operations, and achieve energy savings and emission reductions; moreover, it is one of the primary pathways for lowering energy consumption and enhancing efficiency, with broad prospects for widespread adoption and application.
