[Technical Background]

Flue gas recirculation fans serve as core equipment for efficient operation and environmental compliance in power, metallurgical, chemical, and other industrial sectors. Their impellers are chronically subjected to harsh conditions of high temperature, heavy dust, and intense scouring, leading to frequent wear issues that severely shorten equipment service life and increase operation and maintenance costs. After in-depth research on the wear problems of flue gas recirculation fans, Beijing Titan-Shield Technology, combined with its proprietary [Metal-Ceramic Composite Precision Manufacturing Technology], has thoroughly resolved the wear challenges of flue gas recirculation fans through the dovetail ceramic inlay process.

[Titan-Shield Technical Advantages]

1. Ultra-Wear-Resistant Material Substrate: High-purity silicon carbide ceramic material is employed, with a Mohs hardness of 9, far exceeding that of traditional metal materials. It effectively resists high-velocity scouring and cutting by hard dust particles in flue gas, fundamentally preventing wear escalation and significantly extending equipment service life.

2. Excellent Environmental Adaptability: It offers outstanding high-temperature resistance, capable of stable long-term operation in flue gas environments exceeding 400°C. At the same time, it possesses excellent corrosion resistance, adapting to complex flue gas compositions across multiple industries, preventing material oxidation and deformation, and ensuring operational stability.

3. Robust Composite Process: Titan-Shield's proprietary ceramic composite forming process achieves high-strength bonding between the wear-resistant ceramic layer and the fan impeller substrate, effectively eliminating the risks of ceramic layer detachment and cracking commonly associated with traditional spray or hardfacing processes, thereby enhancing product reliability and service life.

4. Full-Process Quality Control: A comprehensive quality control system is established from raw material selection, precise ceramic layer forming, to rigorous finished product inspection, ensuring that dimensional accuracy and wear resistance of every product meet industry standards and customer operating requirements.

[Applicable Scenarios]

Titan-Shield's [Metal-Ceramic Composite Precision Manufacturing Technology] is widely adaptable to flue gas recirculation fans of various power ratings across scenarios including coal-fired units in the power industry, smelting flue gas treatment in metallurgy, and exhaust gas recirculation in chemicals. Customized anti-wear solutions are available based on different fan models and operating parameters.

[Practical Application Results]

In the flue gas recirculation fan impeller project of China Energy Investment Group, this ceramic anti-wear product was successfully implemented. After commissioning, continuous monitoring by the power plant's equipment department showed that as of December 24, 2025, the impeller equipped with Titan-Shield's [Metal-Ceramic Composite Precision Manufacturing Technology] inlay process had been operating stably for over 800 days. Fan vibration remained within normal range throughout, with no visible wear marks on the impeller surface. The replacement cycle, traditionally 1–2 years for conventional impellers, has been extended to more than 3 years, significantly reducing spare parts procurement and shutdown maintenance costs, ensuring continuous and stable power generation, and earning high recognition from the owner.
