Coal Powder Distributor

       In the vast field of industrial technology, there exists a mysterious entity known as the "New Type Pulverized Coal Distributor." Like a warrior clad in armor, it paves the way for the blast furnace pulverized coal injection system, ushering in a new era.

      This distributor, with its conical shape, stands tall like a mighty giant amidst the waves of industry. It is not merely a simple replacement for bottle-type, disc-type, or ball-type distributors but represents a comprehensive innovation and transcendence of previous equipment. Traditional disc-type and bottle-type distributors often feature horizontally arranged branch pipes. However, during the coal injection process, this design becomes an invisible ordeal. Driven by high-pressure airflow, the pulverized coal flows like a wild torrent, causing wear and tear on the equipment akin to sand grinding against a giant wheel.

       However, our new type pulverized coal distributor skillfully avoids these challenges. It recognizes the shortcomings of older products and addresses them through meticulous design and craftsmanship. This is not just a simple device but a work of art that embodies wisdom and ingenuity.

        This distributor consists of a main pipe, a conical body, and various branch pipes. The branch pipes are evenly distributed across the top of the body like stars in the sky. The conical distribution design features branch pipes arranged at an upward angle, resembling rays of starlight pointing toward the endless universe. The coal injection branch pipes encircle the upper part of the distributor body like a circle of guardians, ensuring even distribution of pulverized coal. The lower end connects to the coal transmission main pipe, while the upper branch pipes link to various coal injection guns, forming a tightly integrated coal injection system.

       It is manufactured from carbon steel structure with precise processing and astonishing geometric accuracy. The internal cavity of the conical body is simple yet cleverly designed, compact in size and lightweight, making maintenance effortless. Its most notable feature lies in the design of the internal cavity. The conical cavity design ensures that the outlet area of each branch pipe complements the inlet channel area. When the solid-gas flow enters the cavity under high pressure, it forms a powerful vortex that tightly envelops the pulverized coal and evenly distributes it to each branch pipe. This design reduces pulsation during transportation, making the injection process more stable and reliable, achieving the user's desired flow rate.

       What is even more remarkable is the distributor's astonishing precision in controlling the coal injection volume at the tuyere. Its control accuracy can reach ±3% of the large coal injection volume, providing a solid guarantee for uniform combustion in the raceway around the blast furnace hearth. The fluid velocity within the pulverized coal distributor remains consistent with the velocity in the pipeline, significantly reducing wear and extending the equipment's service life.
      This distributor abandons the traditional throat structure, thereby reducing resistance loss. It avoids issues such as throat clogging and decreased distribution accuracy caused by uneven throat wear. This pulverized coal distributor is not only suitable for various coal transportation systems under different gas-solid ratios in blast furnace injection systems but can also be flexibly applied in both dilute-phase and dense-phase transportation.
       In this revolution of industrial technology, the new type pulverized coal distributor, with its outstanding performance and exquisite design, has become a reliable assistant for blast furnace pulverized coal injection systems. It provides strong support and assurance for the coal injection ratio of blast furnaces in ironmaking plants. It is not just a piece of equipment but also a witness and driving force behind the progress of industrial civilization.
