2023-10-07

Recently, the Jiangsu Provincial Department of Science and Technology issued a public notice regarding the proposed establishment of new provincial engineering technology research centers and academician workstations for 2023. Jiangsu Longye Energy-Saving Technology Co., Ltd. was recognized as the “Jiangsu Provincial Engineering Technology Research Center for Ultra-High-Temperature Flue Gas Waste Heat Recovery Equipment.” This designation underscores Jiangsu Longye’s robust technological innovation and R&D capabilities in the field of coking‑related energy conservation and environmental protection.

The Jiangsu Provincial Engineering Technology Research Center serves as a key platform that places enterprises at its core, is market‑driven, and fosters deep integration among industry, academia, and research. It is an important mechanism for advancing the development of enterprise R&D institutions and enhancing their independent innovation capabilities. Its objectives are to help enterprises overcome critical, common technological bottlenecks that constrain industrial development, facilitate the commercialization of research outcomes and the dissemination of technologies, and promote technological progress and industrial growth across relevant sectors.

Since 2010, under the leadership of Chairman Meng Xiaodong, our company’s project team has tackled the challenge of efficiently, stably, and reliably recovering waste heat from coke oven riser gas—particularly in conditions characterized by high temperatures, corrosive environments, and cyclical temperature fluctuations. Through collaborative research, the team conducted fundamental studies, optimization, analysis, and comparative evaluations of operating conditions, materials, and structural designs, achieving breakthroughs in core technologies. These advances resolved longstanding technical issues such as riser leakage, tar deposition, and dry‑burning. As a result, we independently developed an advanced, energy‑efficient waste‑heat recovery technology for coke oven riser gas, enabling the successful industrialization, large‑scale deployment, and commercial application of a complete waste‑heat recovery system. This solution effectively addresses the three major challenges of this technology—carbon buildup, tar adhesion, and leakage—ensuring the safe, environmentally friendly, long‑life, and highly efficient operation of riser equipment and systems, while delivering significant energy savings, emission reductions, and strong economic benefits.

“Jiangsu Provincial Engineering Research Center for Ultra-High-Temperature Flue Gas Waste Heat Recovery Equipment” is Jiangsu Longye Following Jiangsu Province High-Tech Enterprise 、 Changzhou City Enterprise Technology Center and several other research and innovation initiatives Another significant qualification approved for construction after the platform’s establishment. The company will seize this opportunity to press ahead with renewed vigor, steadfastly implement its innovation-driven development strategy, further strengthen its capabilities in tackling key core technologies, and refine its industry–university–research collaboration mechanisms, thereby making an even greater contribution to the robust growth of the industry.

The Fifth Congress of the Zhonglou District Science and Technology Association was held, and Meng Xiaodong, Chairman of Jiangsu Longye, was successfully elected Vice Chairman of the Zhonglou District Science and Technology Association.
