The fluidized bed roaster (commonly called boiling furnace) utilizes solid fluidization technology for efficient roasting of sulfide ores and similar materials. The furnace features a steel shell construction with insulation and refractory brick lining.
- Wind chamber with air inlet pipe at base
- Air distribution plate
- Refractory concrete furnace bed with wind caps
- Conical upper section to minimize particle blowout
- Feeding ports, slag outlets, gas exhausts
- Top-mounted explosion-proof ports
Hot air injection through wind cap orifices creates fluidized material movement (similar to boiling water), enabling efficient roasting. Sulfide ore reactions generate heat, sulfur dioxide gas (for sulfuric acid production), and usable metallurgical slag.
- Straight-tube furnace: Primarily for nonferrous metal concentrates with lower roasting intensity
- Upper expansion furnace: Handles block ores and flotation concentrates with higher roasting intensity
- High roasting intensity capable of processing low-grade ores
- Low residual sulfur in slag with high SO₂ concentration in output gas
- Efficient heat recovery for medium-pressure steam generation
- Uniform bed temperature distribution
- Simple, low-maintenance design without moving parts
- High automation with minimal operating costs
- Reduced environmental impact during operation
Requires dust control for furnace gas and significant blower power consumption.
Widely implemented in sulfuric acid production and nonferrous metal smelting for processing pyrite and flotation concentrates.
