Engineered for extreme reliability, industrial efficiency, and environmental compliance.
Wet Flue Gas Desulfurization (WFGD) represents the standard for sulfur dioxide ($SO_2$) removal. Oxidation fans provide crucial continuous airflow to turn calcium sulfite into reusable gypsum ($CaSO_4 \cdot 2H_2O$), ensuring environmental compliance.
Flue gas systems expose blowers to highly acidic, damp, and abrasive environments. ZCBC leverages corrosion-resistant coatings, customized duplex stainless steel, and advanced labyrinth-carbon ring seal technologies to maximize uptime.
With multi-stage centrifugal and high-speed direct-drive options, ZCBC blowers lower parasitic load. We configure energy-optimized aeration designs that drastically decrease standard operating costs (OPEX) in coal and petrochemical plants.
In modern industrial flue gas treatment, wet limestone-gypsum desulfurization remains the dominant process. The system absorbs sulfur dioxide ($SO_2$) using a slurry mixture of limestone and water. However, the resulting calcium sulfite ($CaSO_3$) is highly unstable and cannot be easily filtered or utilized. This is where Desulfurization & Oxidation Fans act as the central circulatory system. By forcing high-volume, continuous oxygen streams through the absorber tower, they convert the calcium sulfite into calcium sulfate dehydrate—commonly known as industrial-grade gypsum.
This conversion process requires massive volumes of air delivered reliably against variable hydrostatic pressures. Any interruption in this oxidation airflow immediately leads to scale buildup inside the tower, chemical imbalance, and eventual shutdown of the entire flue gas system. Consequently, selecting an elite desulfurization & oxidation fan manufacturer is not merely an equipment purchase, but a key operating safeguard for large-scale power generators, chemical works, and metallurgical smelters.
Over 50 years of manufacturing excellence, integrating research, manufacturing, and global logistics.
Shandong Zhangqiu Blower Co., Ltd. (formerly known as Shandong Zhangqiu Blower Works) represents over 50 years of expertise in blower design, engineering, and manufacturing technology. Emphasizing a robust international footprint, ZCBC established two Sino-Japanese Joint-ventures and one USA branch, becoming the first enterprise in China's blower industry to establish overseas branches. Today, ZCBC stands as the leading enterprise in the regional industry, with our signature Roots Blower market share consistently occupying the top position in China's blower industry.
Our overall development strategy—"Develop main business, pioneer new fields and innovate, cooperate to be a great company"—is driven by our core working concept: "Do the best". We have evolved into a modern industrial group that integrates design, manufacturing, and sales of high-performance Roots Blowers, Centrifugal Blowers, Industrial Fans, Heavy-duty Industrial Pumps, Pneumatic Conveying Systems, Electrical Control Equipment, MVR Evaporation systems, Concentration and Crystallization plants, alongside comprehensive wastewater treatment products and services.
In 2005, ZCBC relocated to a newly built, high-standard modern industrial park spanning 430,000 m². This expansive facility provides the physical and logistical infrastructure needed to partner with global engineering houses and complete massive infrastructure projects. On July 7th, 2011, the company achieved a critical milestone by listing on the Shenzhen Stock Exchange (Stock Code: 002598).
By 2020, our parent company realized an operating income of 1.5 billion yuan with profits of 150 million yuan. Today, Zhang Drum owns 20 holding companies and operates four advanced manufacturing bases across Jiangsu Wuxi, Guangdong Dongguan, Hunan Chenzhou, and Gansu Jinchang, supported by dedicated R&D centers in Beijing, Shanghai, Shijiazhuang, and Wuxi.
Understanding the macro shift from basic desulfurization to zero-leakage, high-efficiency, smart flue gas treatment systems.
Globally, environmental regulators are tightening sulfur oxide emission limits. Power and chemical plants must optimize their flue gas desulfurization (FGD) systems to run near 99% efficiency. This requires oxidation fans that can dynamically adapt their output via variable frequency drives (VFD) to match real-time flue gas volumes and sulfur concentrations, eliminating energy wastage.
For smaller wet desulfurization systems (absorber slurry height under 5 meters), Roots blowers remain the standard due to their displacement characteristics. However, large utility-scale FGD plants require heavy-duty Centrifugal and High-Speed Turbo Blowers. The industry is rapidly adopting Permanent Magnet Synchronous Motor (PMSM) direct-drive blowers and Magnetic Suspension Centrifugal blowers, which reduce energy consumption by up to 30% compared to traditional gear-driven options.
Flue gas environments are highly corrosive, with high concentrations of chlorides and sulfurous acids. The industry is moving away from basic cast-iron components toward advanced materials. Modern impellers are manufactured from titanium, duplex stainless steel (such as 2205 or 2507), or treated with specialized anti-wear thermal spraying. This prevents chemical attack and particle abrasion, ensuring the blowers maintain aerodynamic profile integrity over long operating cycles.
Leading environmental engineering groups now specify complete packages. ZCBC provides complete engineering designs, integrating the air blowers with downstream slurry pumps, ceramic desulfurization pumps, and pneumatic gypsum conveying systems. By sourcing the entire fluid path from a single qualified supplier, operators ensure optimized system curves, unified control interfaces, and simplified maintenance routines.
