AI Technical Summary
When pulverized coal is injected into laterite nickel ore, excessive concentration of pulverized coal can lead to localized overheating or insufficient reduction. Existing mechanical structures are complex and inconvenient to maintain.
It adopts a dispersion injection structure and an anti-caking structure, including a dispersion hood, injection channel, powder blowing hole and anti-caking screen plate. The physical structure realizes the uniform dispersion and refinement of coal powder and prevents agglomeration. The coal powder is preheated by heating wire and the powder blowing hole is cleared by gas.
It achieves uniform injection of pulverized coal and expands the injection area, preventing local overheating or insufficient reduction, simplifying the device structure, reducing the failure rate and maintenance difficulty, and improving combustion efficiency.
