Introduction to Pulverized Coal Distributor

       Poetic Version of Product Description
       A structural marvel, it serves as the bridge that evenly distributes pulverized coal to the blast furnace tuyeres in the coal injection system. Our company's newly developed coal distributor incorporates the essence of previous designs while integrating advanced foreign technology.
This distributor features a conical design, surpassing older bottle, disc, and spherical types. Traditional bottle and disc branch pipes often have horizontal layouts, whereas coal injection systems rely on airflow pressure for transportation, inevitably causing equipment wear. Previous distributors either had throat structures with high resistance, unreasonable internal cavity designs leading to significant pulsation during coal flow, unstable injection volumes, uneven distribution, or severe equipment wear.

       This product is the perfect solution to the aforementioned issues. It consists of a main pipe, conical body, and multiple branch pipes uniformly arranged at angles (such as 90 or 120 degrees) atop the cone, showcasing exquisite craftsmanship. The coal injection branch pipes (e.g., 8, 10, 12) are evenly distributed around the body, connecting the coal supply main pipe to the coal injection guns.

      Crafted from carbon steel with precision manufacturing and high geometric accuracy, its conical internal cavity is both simple and ingenious—compact, lightweight, and easy to maintain. The unique internal design ensures that the outlet area of each branch pipe matches the inlet channel area. When high-pressure solid-gas flow enters the cavity, it forms a powerful vortex that envelops the coal particles, silently distributing them to every branch. This design minimizes pulsation, ensures stable and reliable injection, achieves ideal flow rates, and prevents swirling or pulsation during coal transit.

       This distributor achieves remarkable precision in controlling coal injection volume at tuyeres, with errors within ±3% even under high injection rates. Such design promotes uniform combustion in the raceway around the blast furnace hearth. The coal flow velocity within the distributor matches that in the pipelines, reducing wear and extending lifespan. Notably, it eliminates traditional throat structures, significantly cutting resistance losses and avoiding throat clogging or precision degradation due to uneven wear.

  
       This coal distributor, poetic and picturesque, is suitable for pulverized coal transportation under various gas-solid ratios in blast furnace injection systems, adeptly handling both dilute and dense phase demands. It is not only a technological achievement but also an artistic embodiment.
