Project Background
Kaifeng Xinli Boiler Equipment Co., Ltd. is a state-designated manufacturer of small-to-medium-sized boilers and a leading domestic R&D hub for external circulation fluidized bed (CFB) boilers. Leveraging cutting-edge technical collaboration with the Chinese Academy of Sciences, its core product portfolio encompasses a wide range of boiler systems, including high-efficiency energy-saving CFB boilers, conventional oil- and gas-fired boilers, and new-energy biomass boilers. For such advanced thermal equipment, high-efficiency, stable industrial boiler blowers serve as the vital “heart” that ensures complete fuel combustion and optimal system thermal efficiency.
Application Scenarios and Challenges
Modern industrial boilers operate under extremely complex and variable conditions. From conventional coal-fired/chain-grate boilers to biomass and waste-to-energy boilers subject to stringent emission standards, different combustion media impose vastly different requirements on forced draft and flue gas exhaust systems. In particular, for high-load waste incineration and biomass power generation projects, the associated induced draft fans and exhaust fans must withstand long-term exposure to high-temperature corrosion, heavy dust accumulation, and rapidly fluctuating ductwork resistance. Any degradation in aerodynamic performance or mechanical failure can directly lead to forced load reduction or even critical boiler shutdowns.
Yutong’s Solutions and Core Strengths
With unparalleled expertise in thermal ventilation, Yutong Blower has become a core strategic supplier for this national-level boiler manufacturing base. To date, we have delivered over 3,500 industrial fans catering to various boiler types, with the largest supported boiler capacity exceeding 400 t/h.
Throughout our long-term partnership, we have demonstrated exceptional capabilities in supporting heavy-duty boiler systems:
Precision Aerodynamic Matching Across the Full Spectrum of Boiler Types
Rather than offering “one-size-fits-all” standard components, Yutong precisely customizes forced draft (FD) and induced draft (ID) fan combinations tailored to specific processes—including CFB, chain-grate, biomass, and waste incineration technologies. Through optimization using proprietary fluid dynamics models, we ensure the fan output curve aligns perfectly with the boiler’s combustion and flue gas exhaust requirements, delivering exceptional system-wide energy efficiency.
Heavy-duty, heat-resistant design with ash and corrosion resistance
To withstand the harsh operating conditions—characterized by high concentrations of abrasive fly ash and high-temperature acidic gases in the flue gas—we have upgraded our core CFB (Circulating Fluidized Bed) boiler fans. Enhancements include specially thickened, wear-resistant impellers and premium water-cooled bearing housings, significantly boosting erosion resistance and extending maintenance-free service intervals in extreme exhaust environments.
Value Delivered to the Customer
A track record of over 3,500 delivered units serves as the ultimate testament to the exceptional reliability of Yutong fans. With rock-solid engineering quality, outstanding cost-performance, and extensive experience supporting a full range of thermal energy equipment, Yutong consistently provides robust, reliable propulsion for the client’s advanced boiler systems. We not only help enhance the combustion thermal efficiency and environmental compliance of the client’s equipment packages but also—through consistently dependable, long-term performance—support the success of high-quality Chinese boiler equipment in both domestic and international markets.
