Pulverized Coal Distributor (Steel Plant, Power Plant) DN125/DN40-6
Other Products
The pulverized coal distributor (DN125/DN40-6) is a key equipment in blast furnace coal injection systems of steel mills and coal milling systems of power plant boilers. It is mainly used to evenly distribute pulverized coal to multiple injection branch pipes to ensure combustion stability. Below are its core parameters and features:
Technical Parameters
Nominal Diameter: DN125 (main pipe), DN40-6 (branch pipe)
Applicable Medium: Dry pulverized coal, operating temperature ≤80℃, pressure 1.6MPa
Distribution Accuracy: Error of coal injection volume per tuyere ≤±3%
Structural Design
Body Type: Cone type, disc type, bottle type are optional. The cone-type branch pipes adopt elevation angle distribution (90° or 120°) to optimize airflow.
Wear-Resistant Material: The inner wall is coated with wear-resistant alloy, ceramic or stainless steel to extend service life
Installation Method: Connect vertically to the main pulverized coal pipe, with a height of only 2~3m, which is convenient for layout on the tuyere platform
Application Advantages
Even Distribution: Reduces eddy current through the conical inner cavity structure, avoids coal accumulation, and ensures consistency of multi-pipe injection
Energy Saving and Environmental Protection: Reduces the risk of combustion deviation caused by uneven distribution, and reduces energy consumption and pollution
Compatibility: Adaptable to single-pipe coal injection systems, with customizable number of branch pipes (6~35 pipes)
Typical Scenarios
Steel Mills: Used in blast furnace coal injection systems to ensure uniform combustion in the furnace hearth
Power Plants: Distributes pulverized coal to boiler burners in direct-fired coal milling systems to prevent flame deviation
