EXPERIENCE THE
FURNACE TECHNOLOGY TRUSTED WORLDWIDE
BSP Thermal Systems, Inc. leads the industry in designing and manufacturing high-performance multiple hearth furnace systems. With over 100 years of engineering excellence, we deliver powerful, cost-effective thermal solutions for carbon activation, metal recovery, incineration, ore roasting, and more.
Our multiple hearth furnaces are built for precision and process flexibility. Designed with a vertical, cylindrical steel shell lined with refractory material, each furnace houses multiple hearths stacked one above the other. A central rotating shaft with radial arms moves the material through the system, allowing for controlled exposure to heat and gases at each stage.
This multi-zone approach enables tailored temperature control, enhanced heat transfer, and efficient material movement — all while maintaining low operating and maintenance costs. With customizable features such as gas flow direction, burner placement, and shaft speed control, BSP furnaces adapt to a wide range of materials and process requirements.
Key Advantages of BSP Multiple Hearth Furnace Systems:
- Modular, customizable hearth configurations
- Low NOx burner options and heat recovery systems
- Energy-efficient with countercurrent gas/material flow
- High throughput with a small footprint
