The Shandong Jinglan pulverized coal distributor is an indispensable component in the ironmaking pulverized coal injection system. It comes in various types, including the upward-angle type, bottle type, and disc type, each designed to suit specific working conditions. This equipment consists of a main pipe, a body (which can be conical, disc-shaped, bottle-shaped, etc.), and multiple branch pipes. The branch pipes are evenly distributed above the body, with the conical body's branch pipes arranged at upward angles such as 90 or 120 degrees. The number and diameter of the coal injection branch pipes are standardized, such as 8, 10, 12, 14, 16, 18, etc., and all are connected to the pulverized coal lances.
 

      The body of the pulverized coal distributor is made of carbon steel structure, featuring high-precision machining and geometric accuracy. Particularly, the conical inner cavity design is both simple and compact, with a small volume and lightweight, making maintenance more convenient. Additionally, the outlet area of the branch pipes is similar to the inlet channel area. Utilizing airflow characteristics, when the solid-gas flow enters the inner cavity under high pressure, it forms a vortex that effectively envelops the pulverized coal and evenly distributes it to each branch pipe.

      Among these, the YFPQ type upward-angle pulverized coal distributor is specifically designed for single-pipeline pulverized coal conveying systems in ironmaking coal injection. It ideally distributes pulverized coal for multi-pipe injection at the furnace front. Its outlet pipe diameters come in three specifications: 15, 20, and 25, and it offers two connection methods—flange and threaded—providing flexibility to meet different needs.

      As a key component of the blast furnace pulverized coal injection system, the pulverized coal distributor is responsible for evenly distributing pulverized coal to the blast furnace tuyeres. It comes in a wide variety of types: by shape, there are bottle type, spherical type, disc type, etc.; by branch pipe material, there are wear-resistant alloy type and wear-resistant ceramic type, among others. With the continuous increase in the blast furnace coal injection ratio, the working efficiency of the pulverized coal distributor faces severe challenges. To address this, our company has carried out technical modifications and process optimizations on the pulverized coal distributor to enhance its efficiency and stability.
      In summary, the pulverized coal distributor is an indispensable device in the blast furnace pulverized coal injection system. Its precision in design and manufacturing, along with its unique structure, reflects our pursuit of craftsmanship and efficiency. Through continuous technological innovation and process improvements, we ensure the performance and quality of the pulverized coal distributor to meet the growing demands of ironmaking plants.
