High-Efficiency Fluidized Bed Boilers from ZOZEN Boiler: Reliable, Clean, and Adaptable Energy Solutions

In modern industrial production, energy efficiency and environmental protection have become critical factors influencing enterprise competitiveness. Among various types of industrial boilers, fluidized bed boilers have gained remarkable attention due to their ability to achieve efficient combustion, low emissions, and wide fuel adaptability. Compared with traditional grate or pulverized coal boilers, fluidized bed boilers feature excellent fuel flexibility and stable combustion across different load ranges. They can utilize various low-grade solid fuels such as coal, biomass, and industrial waste, while maintaining efficient heat transfer and reduced pollutant formation.

Among the global manufacturers specializing in advanced industrial boilers, ZOZEN Boiler stands out for its engineering expertise and extensive application experience in fluidized bed technology. The company’s SHX series fluidized bed boilers have been widely used in various industries requiring reliable steam supply and environmentally compliant operation.

Technical Strength of ZOZEN SHX Series Fluidized Bed Boilers

The SHX series fluidized bed boilers developed by ZOZEN represent the company’s continuous pursuit of innovation, reliability, and clean combustion technology. These boilers adopt a circulating fluidized bed design, which operates under low-temperature combustion conditions. The furnace structure ensures that the fuel particles remain suspended and fully mixed with air, forming a uniform and stable combustion zone. This not only improves the burnout rate of solid fuels but also effectively suppresses the generation of nitrogen oxides, meeting stringent environmental standards.

One of the core advantages of ZOZEN’s SHX series fluidized bed boilers lies in their in-furnace desulfurization capability. By injecting limestone or other desulfurizing agents directly into the furnace, sulfur dioxide is captured during combustion, achieving a high desulfurization rate without requiring a separate external treatment system. This design simplifies the overall process and reduces operating costs while ensuring stable emission performance over long-term operation.

The boiler also features a high-temperature cyclone separator that enables efficient particle separation and recirculation. With a separation efficiency of 98% or higher, the system ensures that unburned particles are returned to the furnace for complete combustion. This enhances fuel utilization and minimizes unburned carbon in fly ash. The inner walls and critical wear-prone areas of the separator are lined with abrasion-resistant materials, significantly extending the boiler’s service life even under high-load and continuous operation.

In terms of structural design, the SHX fluidized bed boiler incorporates a large-volume furnace and low gas velocity configuration. This combination allows the fuel particles to stay longer within the furnace, ensuring complete combustion and higher thermal efficiency. The convection heating surfaces are equipped with multiple gas-baffling plates, effectively extending the flue gas path to enhance dust collection and improve heat exchange performance. Additionally, the inclusion of serpentine-tube economizers and air preheaters further enhances energy recovery, helping the boiler achieve an overall thermal efficiency of about 88% under standard operating conditions.

ZOZEN’s fluidized bed boilers are also known for their high degree of automation and intelligent operation. Advanced control systems with real-time monitoring functions help operators precisely regulate air distribution, fuel feeding, and pressure stability, ensuring optimal combustion conditions at all times. The entire system can adapt to variations in fuel quality, load demand, and operating altitude, providing flexibility and reliability across different industrial applications.

SHX Fluidized Bed Boiler Serving a Silicon Chemical Enterprise

A prominent silicon chemical enterprise recently partnered with ZOZEN Boiler to upgrade its energy system and improve both production efficiency and environmental performance. The company’s production processes—such as drying and heat treatment—require a stable and controllable heat source, making the choice of a high-performance industrial boiler critical.

As market demand for the company’s products continued to grow and national environmental regulations became more stringent, the enterprise decided to replace its outdated boilers with a more advanced and cleaner alternative. After a comprehensive assessment of production requirements, fuel characteristics, and environmental compliance targets, ZOZEN proposed a customized SHX series circulating fluidized bed steam boiler as the ideal solution.

The system operates under low-temperature combustion conditions, which inherently reduces nitrogen oxide formation. At the same time, limestone is injected during combustion to achieve direct in-furnace desulfurization, providing a simple and cost-effective method for meeting emission limits. The high-temperature cyclone separator ensures efficient separation of fine particles, allowing unburned fuel to be recirculated into the furnace for complete combustion. The robust and wear-resistant separator design guarantees consistent operation even under long-term, high-intensity industrial use.

The boiler’s large furnace volume, low gas velocity, and optimized air distribution ensure prolonged fuel residence time and uniform temperature profiles, both of which are essential for stable heat delivery during drying and processing. The convection section, equipped with multiple baffle plates, enhances dust collection and improves heat transfer efficiency. In addition, the serpentine economizer and air preheater recover residual heat from the exhaust gas, raising the feed water temperature and reducing fuel consumption. Field measurements during commissioning indicated that the overall thermal efficiency exceeded 88%, meeting both the energy performance and environmental expectations of the project.
