SZL Series Coal-Fired Chain Grate Boilers

High-Efficiency SZL Series Coal-Fired Chain Grate Boilers for Industrial Applications

The SZL series represents a new generation of high-performance, shop-assembled water tube chain grate boilers, engineered for versatility and reliability. Designed as a double-drum, longitudinal-type boiler, this series excels in utilizing a wide array of solid fuels, including bituminous coal, anthracite, and smokeless coal, making it a flexible solution for various industrial energy needs. The core design consists of an upper and lower drum arranged longitudinally, with a dense assembly of water-cooled membrane walls forming the furnace. The convection tube bank, situated between the drums, ensures efficient heat exchange, maximizing thermal output.

Key Features and Advantages

• High Thermal Efficiency: With a sophisticated furnace design and optimized heat transfer surfaces, the SZL series achieves an impressive thermal efficiency of up to 87.7%, significantly reducing fuel consumption and operational costs.
• Compact and Modular Design: These boilers feature a compact structure that simplifies transportation and installation. The modular design minimizes on-site construction work, reducing initial investment and project timelines.
• Mechanized Operation: Equipped with a high-quality chain grate stoker, the boiler automates the processes of coal feeding and slag removal. The electrical control system allows for stepless speed regulation of the grate, ensuring optimal combustion under varying loads.
• Rapid Response and Stable Output: The water-tube design facilitates quick start-up, rapid pressure raising, and a stable supply of high-quality steam or hot water, making it ideal for industries with fluctuating energy demands.
• Enhanced Safety and Reliability: The system is integrated with comprehensive safety features, including limit parameter alarms and interlock protection, to ensure safe and reliable operation around the clock.
