Pulverized Coal Distributor Hebei

        Generally, pulverized coal distributors are classified by shape into bottle type, ball type, disc type, cone type (inclined type), curved branch pipe type, etc., and by branch pipe material into wear-resistant alloy type, wear-resistant ceramic type, etc. With the gradual increase of coal injection ratio in blast furnaces of major ironworks, the working capacity of coal injection distributors has been severely challenged. To address this challenge, our company has timely carried out technological transformation and process improvement on the coal injection distributor to ensure it always maintains a leading position in the industry.
Xiangye pulverized coal distributor is an indispensable key equipment in the ironmaking coal injection system. Its types include inclined type, bottle type and disc type pulverized coal distributor, each suitable for specific working conditions.
I. YFPQ Type Inclined Pulverized Coal Distributor
This distributor is specially designed for the single-pipe pulverized coal conveying system of ironmaking coal injection, and can realize uniform distribution of pulverized coal injected from multiple pipes in front of the furnace. Its outlet pipe diameter can be selected from 6 to 35 pipes, with three specifications of 15, 20 and 25, and supports two connection methods: flange and threaded connection, providing a reliable guarantee for the smooth conveying of pulverized coal.

II. PFPQ Type Bottle Pulverized Coal Distributor
Although this bottle-type pulverized coal distributor has no specific description, its stable performance and high-efficiency working mode can be imagined, and it will definitely play an important role under specific working conditions.

III. PSFPQ Type Disc Pulverized Coal Distributor

Product Description and Structural Features: The PSFPQ disc-type pulverized coal distributor is a key equipment in the blast furnace coal injection system that dominates the average distribution and conveying of pulverized coal. This distributor newly developed by our company not only draws on the advantages of various types of distributors in the past, but also combines with foreign advanced technology. It adopts a conical design, which has actually replaced the old-style bottle-type, disc-type and ball-type distributors. The branch pipes of traditional bottle-type and disc-type distributors are mostly horizontally distributed, but in the coal injection system, the pulverized coal conveyed by air flow with a certain pressure will cause large wear to the equipment. Moreover, previous distributors had various problems, such as some having a throat structure leading to large resistance, some unreasonable inner cavity structure causing pulsation when pulverized coal passes through, resulting in unstable coal injection volume, and some uneven distribution, severe equipment wear, etc.

Our new pulverized coal distributor recognizes the seriousness of these problems and is designed to solve them. The product consists of a main pipe, a main body (including cone type, disc type, bottle type) and each branch pipe, and the branch pipes are evenly distributed above the main body. Among them, the cone type is designed with each branch pipe distributed at an elevation angle (such as 90 degrees or 120 degrees), and the coal injection branch pipes (such as 8, 10, 12 pipes, etc.) are evenly distributed around the upper part of the distributor main body. The lower end of the distributor is connected to one end of the coal conveying main pipe, and the upper branch pipes are connected to each pulverized coal lance.

      This product is made of carbon steel structural parts, with precise processing and high geometric accuracy. The inner cavity of the cone has a simple structure, small volume, light weight and convenient maintenance. Its inner cavity is ingeniously designed, and the sum of the outlet areas of each branch pipe is close to the area of the inlet channel. When the supplemented high-pressure solid-gas flow enters the inner cavity, a strong vortex will be formed, tightly wrapping the pulverized coal and evenly distributing it to each branch pipe. Such a design makes the conveying process have small pulsation, stable and reliable injection, and can fully meet the ideal flow requirements of users. More importantly, when pulverized coal flows through the distributor, there is no swirl or pulsation, ensuring the accuracy and stability of coal injection.

      Under the precise control of our distributor, the control accuracy of coal injection volume at each tuyere can reach ±3% of the large coal injection volume, which fully ensures the uniform combustion of the raceway around the blast furnace hearth. The flow rate of fluid in the pulverized coal distributor is consistent with the flow rate in the pipeline, so it has small wear and long service life. In addition, this coal injection distributor has no throat structure, with small resistance loss, avoiding the phenomenon of throat blockage and the problem of reduced distribution accuracy caused by uneven throat wear.
It is worth mentioning that our pulverized coal distributor has wide applicability. It is not only suitable for pulverized coal conveying systems under various gas-solid ratios in blast furnace coal injection systems, but also can be used for dilute phase and dense phase conveying. As a special equipment for blast furnace coal injection system, the pulverized coal distributor is a special-shaped structural part equipment, with complex manufacturing process and high process requirements. However, by virtue of advanced technology and fine processing technology, we ensure the quality and performance of the product.
      In conclusion, our pulverized coal distributor provides reliable guarantee for the blast furnace coal injection system with its excellent performance and stable performance, and is an indispensable key equipment in the ironmaking industry.
