Coal Powder Distributor

Lanhao Environmental Protection produces carbon steel and stainless steel pulverized coal distributors. The following is a systematic summary of the core functions, structural types, and application points of pulverized coal distributors in blast furnace pulverized coal injection systems in steel plants:
1. Core Functions
Uniform distribution of pulverized coal
Evenly distributes the mixed flow of pulverized coal and gas transported through the main pipeline to multiple branch pipes (typically 6-35 branches), ensuring consistency in pulverized coal injection volume at each blast furnace tuyere, with a distribution accuracy of up to ±3%.
Utilizes a conical cavity design to create a vortex effect, eliminating airflow pulsation and achieving stable transportation.

2. Structural Types and Characteristics
Type‌ ‌Structural Features‌ ‌Applicable Scenarios‌
Conical Type (Elevated Angle Type)‌ Branch pipes distributed at 90° or 120° elevation angles, with a conical inner cavity forming a vortex; vertical installation height requires only 2-3m, with low resistance and minimal wear‌ Single-pipeline injection systems, suitable for both dense and dilute phase transportation‌
Disk Type‌ Conical分流 structure replaces traditional bottle/ball types, eliminating the risk of throat blockage and improving distribution uniformity‌ High pulverized coal injection ratio and long-distance transportation scenarios‌
Bottle Type‌ Wear-resistant alloy or ceramic lining, strong resistance to冲刷; prone to powder accumulation in early designs, now mostly replaced by conical/disk types‌ Specific blast furnace改造 projects‌
