As one of the important industrial countries in southern Africa, Zimbabwe has been actively promoting the recovery and development of its domestic manufacturing sector in recent years. In paper recycling and papermaking processes, steam is essential for pulping, heating, drying, and other key production steps. ZOZEN’s engineers recommended the SZL12-1.6-AII model, a widely used configuration within the SZL series. This 12t/h SZL Coal-Fired Steam Boiler has earned strong recognition in international markets and is particularly well suited for industries that require reliable long-term operation, such as paper manufacturing and recycling plants.

ZOZEN 12t/h SZL Coal-Fired Steam Boiler

One of the major advantages of the 12t/h SZL Coal-Fired Steam Boiler is its structural design. The boiler adopts a double-drum longitudinal layout with a water-tube structure, which enhances heat transfer efficiency and ensures stable steam generation. This design allows the boiler to maintain consistent performance even during extended operating periods, which is essential for the continuous processes commonly found in the paper recycling industry.

Another important feature of the 12t/h SZL Coal-Fired Steam Boiler is its combustion system. The boiler is equipped with a chain grate stoker, which is designed to ensure stable and efficient coal combustion. Working together with a compartmentalized air supply system, the chain grate enables different air distribution levels throughout the combustion stages. This allows the fuel to burn more completely, improving fuel utilization and reducing unburned residues. As a result, the 12t/h SZL Coal-Fired Steam Boiler helps the enterprise lower fuel consumption while maintaining steady steam output.

Efficiency is also a key consideration in industrial boiler operation. The 12t/h SZL Coal-Fired Steam Boiler is designed with optimized heating surface arrangements to maximize heat absorption. According to product performance data, the thermal efficiency of ZOZEN’s SZL series coal-fired boilers can exceed 81%, which is competitive among similar industrial boilers. This level of efficiency allows paper recycling enterprises to reduce operating costs while maintaining reliable production performance.

The 12t/h SZL Coal-Fired Steam Boiler also offers practical advantages for overseas projects. Since international transportation and installation conditions can vary, ZOZEN designs the boiler structure to simplify delivery and on-site assembly. Major components are prepared and tested before shipment, which helps shorten the installation period once the equipment arrives at the project site in Zimbabwe. For industrial users, this means faster commissioning and earlier production startup.

ZOZEN Boiler’s experience in overseas markets also played an important role in the success of this project. With more than three decades of manufacturing and engineering expertise, the company has delivered industrial boiler solutions to many countries. In Africa, ZOZEN has participated in projects in regions such as South Africa and Ethiopia, accumulating valuable experience in adapting boiler systems to local fuel conditions and industrial requirements. The Zimbabwean client selected the 12t/h SZL Coal-Fired Steam Boiler not only for its technical performance but also for the manufacturer’s proven international project capability.

For ZOZEN Boiler, exporting equipment means more than delivering products—it also includes technical expertise and reliable service. With internationally recognized certifications such as ASME and CE, every 12t/h SZL Coal-Fired Steam Boiler meets strict global standards.
