Fluidized Bed Roasting Furnace Overview

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, including specialized high alumina bricks for superior heat resistance.

Structure and Operation

Structure: Comprises a wind chamber with air inlet pipe at base, air distribution plate, refractory concrete furnace bed with wind caps, and conical upper section to minimize particle blowout. Includes feeding ports, slag outlets, gas exhausts, and top-mounted explosion-proof ports.

Principle: 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.

Furnace Types

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

Performance Characteristics

Advantages:

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

Limitations: Requires dust control for furnace gas and significant blower power consumption.

Industrial Applications

Widely implemented in sulfuric acid production and nonferrous metal smelting for processing pyrite and flotation concentrates.
