AI Technical Summary
In the dry slag discharge system of industrial boilers, high-temperature coal slag accumulates on the surface of the steel belt to form a dense layer, which hinders the penetration of cooling air, resulting in insufficient heat exchange and low waste heat recovery rate.
The coordinated design of conveying elements, heat exchange elements and self-cleaning elements, including slag pits, extrusion bins, steel belts, pits, one-way valves, centrifugal fans and other components, forms a stable airflow channel, destroys the dense stacking structure, enhances the cooling air penetration ability, and optimizes the airflow path through the heat-conducting fins and pit arrays to achieve efficient waste heat recovery.
It effectively reduces cooling air penetration resistance by 40%-60%, improves heat exchange efficiency by 25%-35%, reduces slag residue by 80%, reduces fan energy consumption by 15%-20%, and reduces maintenance costs by 50%.
