Project Background

Henan Xinlianxin Fertilizer Co., Ltd. is a chemical giant and the first in China to achieve dual listing in domestic and overseas markets. Its comprehensive production capacity ranks among the top four in the national fertilizer industry (boasting a massive annual capacity of millions of tons across products such as synthetic ammonia, urea, and compound fertilizers), and it hosts a state-level postdoctoral R&D base. For such a massive, continuous-operation chemical enterprise, highly stable, corrosion-resistant, and durable chemical processing blower systems are critical to ensuring safe production and environmental compliance.

Application Scenarios and Challenges

Following the Ministry of Environmental Protection’s new regulations on atmospheric pollutant emissions, the Xinlianxin Group launched a major technical upgrade project for boiler flue gas emissions—an initiative included in the national central budget investment plan. The waste gas conditions within the fertilizer plant’s production systems are extremely complex, often containing a mixture of corrosive chemicals and dust. This demands that the associated boiler induced-draft (ID) fans and flue gas exhaust fans possess exceptional corrosion resistance and the ability to operate continuously without failure. Any degradation in aerodynamic performance or mechanical failure could directly lead to critical emission violations and incur heavy environmental penalties.

Yutong’s Solution and Core Strengths

As a long-standing strategic supplier to the Xinlianxin Group, Yutong Blower had previously successfully delivered fan equipment for several of the group’s large-scale projects in Changji and Kuqa, Xinjiang. Based on the flawless operational track record of the existing equipment and a foundation of long-term mutual trust—and following a rigorous comparison of technical upgrade proposals—the client once again firmly selected Yutong as the core fan supplier for this major national-level environmental protection project. We custom-engineered and delivered multiple sets of heavy-duty centrifugal fans—featuring the classic 4-68 series—demonstrating our exceptional capabilities in technical upgrade projects:

Advanced Corrosion Resistance and Stable Airflow

Addressing the complex characteristics of chemical fertilizer boiler exhaust, Yutong selected specialized materials and optimized casing anti-corrosion processes. This ensures the equipment maintains superior mechanical strength and stable static pressure output while continuously handling corrosive flue gases.

High-Efficiency Aerodynamic Upgrades

Aligned with the project’s core goal of a “circular economy focused on energy conservation,” Yutong’s fluid dynamics team recalculated and aerodynamically upgraded the ductwork. Our custom fans not only perfectly met the airflow requirements of stringent new standards but also significantly reduced overall system energy consumption through excellent aerodynamic efficiency, achieving genuine cost savings and performance optimization.

Value Delivered to the Customer

By providing mature, cost-effective, and highly reliable ventilation equipment, Yutong Blower successfully supported the flue gas environmental upgrades for multiple production lines at Xinlianxin Group’s No. 1, No. 2, and No. 4 branches. We effectively helped the enterprise drastically reduce pollutant emissions, comprehensively enhancing both environmental and economic benefits. Yutong Blower has once again proven through real-world results that we are a trusted, long-term partner for top-tier global chemical and fertilizer enterprises seeking high-quality ventilation solutions.
