CFBC Boiler: Efficient and Sustainable Energy Solutions from ZOZEN Boiler

In the evolving global energy market, industries are continuously searching for boiler systems that deliver high efficiency, low emissions, and flexible fuel adaptability. Among the many advanced combustion technologies, the CFBC boiler (Circulating Fluidized Bed Combustion boiler) has become one of the most widely adopted solutions for industrial steam and power generation.

A CFBC boiler operates on the principle of fluidized combustion, where a mixture of air and solid fuel particles circulates within the furnace at relatively low combustion temperatures. This process ensures uniform heat distribution, minimizes nitrogen oxide emissions, and allows in-furnace desulfurization for efficient sulfur control. Due to its ability to burn a wide variety of fuels, including low-grade coal, biomass, and agricultural residues, the CFBC boiler has gained popularity in industries such as chemicals, metallurgy, power generation, construction materials, and food processing.

In this competitive landscape, ZOZEN Boiler has emerged as a trusted manufacturer of advanced industrial boilers. Backed by decades of engineering expertise, ZOZEN provides CFBC boiler systems that are technically sophisticated, highly efficient, and tailored to the specific production needs of customers around the world.

SHX Series CFBC Boiler: Parameters, Technology, and Advantages

Among ZOZEN’s product range, the SHX series CFBC boiler has earned strong recognition for its advanced design and performance. This series is primarily used for medium and large-capacity steam applications, providing evaporation capacities ranging from 10 tons per hour up to more than 35 tons per hour, depending on the model and configuration. With working pressures typically reaching 1.25 to 2.5 MPa, the SHX CFBC boiler is capable of delivering reliable and high-quality steam for diverse industrial processes.

From a technical standpoint, the SHX CFBC boiler offers significant advantages over conventional combustion systems. One of the most prominent features is its low combustion temperature. Operating at 194–400°C, the boiler effectively suppresses the formation of nitrogen oxides while enabling in-situ desulfurization through the direct injection of limestone. This results in high desulfurization efficiency without requiring extensive external flue gas treatment systems, helping enterprises comply with strict emission standards.

The furnace of the SHX CFBC boiler is designed with a large combustion chamber and low flue gas velocity, which increases the residence time of fuel particles. This design ensures complete combustion, reduces carbon content in the ash, and lowers fuel consumption, bringing significant cost savings to enterprises. In addition, the boiler is equipped with a high-temperature resistant cyclone separator, developed through ZOZEN’s proprietary technology. This separator enhances the recirculation of fine particles, improving combustion efficiency and reducing erosion on furnace walls.

Another notable technical feature is the use of an advanced air preheater system. By lowering flue gas temperatures and preheating combustion air, the boiler maximizes thermal efficiency while reducing overall energy losses. This integration not only increases output but also optimizes energy utilization.

For operational flexibility, the SHX CFBC boiler is designed with an innovative air chamber system, allowing both over-bed ignition and under-bed ignition modes. This dual ignition option ensures that the boiler can adapt to various operational requirements, providing greater reliability across different production processes.

Durability is also a strong focus of the SHX CFBC boiler. Wear-resistant materials and water-cooled structures are widely applied in the furnace and cyclone separator to extend service life. Combined with automated control systems, the boiler allows for precise adjustment of load, combustion air distribution, and fuel feeding, simplifying daily operations and reducing labor costs.

CFBC Boiler Supporting Soy Peptide Production

The versatility and reliability of the CFBC boiler are well illustrated by ZOZEN’s successful project with a biotechnology company specializing in soybean deep processing. This enterprise focuses on extracting high-value components from non-GMO soybeans, including isoflavones, oligosaccharides, concentrated protein, and composite functional ingredients. In recent years, the company expanded its operations by adding a high-capacity soy peptide production line, along with modern packaging facilities and a research and development center.

For the new peptide production line, steam was identified as a critical energy source. Processes such as drying, concentration, separation, and purification all require stable and high-quality steam. Given the scale and complexity of the production line, the enterprise needed a reliable boiler system that combined high efficiency, flexible fuel adaptability, and strong environmental performance.

After thorough evaluation, the company chose ZOZEN’s SHX series CFBC boiler as the primary heat source. This decision was based on the boiler’s ability to achieve low-temperature combustion with high in-furnace desulfurization efficiency. For the customer, this meant not only compliance with environmental regulations but also long-term operational savings.

ZOZEN’s SHX CFBC boiler used in this project was equipped with a high-efficiency cyclone separator and an advanced air preheater. These technologies reduced flue gas temperature, increased furnace air inlet temperature, and improved the overall thermal efficiency of the system. In addition, the boiler’s spacious furnace design and low gas velocity extended fuel residence time, ensuring complete combustion and minimizing fuel wastage.

To further meet the specific requirements of the soybean peptide production process, ZOZEN engineers customized the boiler’s wind chamber system. This provided the customer with flexible ignition options and stable operation across varying production loads. With the SHX CFBC boiler in place, the company secured a reliable energy supply for its growing production lines, laying a solid foundation for future business expansion.
