Air Replenisher (Air Replenishment Regulator) DN100 / DN25 PN16
The air supplement regulator (air supplement device) DN100/DN25 PN16 is a key equipment in blast furnace pulverized coal injection and pneumatic conveying systems, mainly used for dense-phase conveying of powder materials such as pulverized coal. It achieves stable and efficient solid-gas mixing by adjusting the air supplement volume. The following are its core parameters and features:
Technical Parameters
Nominal Diameter: DN100 (main pipe), DN25 (air supplement pipe)
Design Pressure: PN16 (1.6MPa)
Applicable Medium: Pulverized coal + nitrogen/air, design temperature 100℃
Adjustment Method: Achieve precise gas volume control via air supplement regulating valve or gas volume adjustment bolt
Structural Features
Dual-pipe Design: The central pipe conveys pulverized coal, and the outer ring pipe supplements air; the jet angle is optimized for mixing effect.
Wear-resistant Material: Adopts metallurgical composite bimetallic pipe, with inner layer of wear-resistant steel and outer layer of weldable carbon steel, ensuring long service life.
Adjustable Air Supplement Device: Equipped with air supplement regulating seat and bolts, supporting stepless adjustment of gas volume.
Application Advantages
Stable Conveying: Destroys the material column to realize long-distance dense-phase conveying.
Energy Saving and Environmental Protection: Reduces gas waste and lowers pipeline wear.
Compatibility: Compatible with components of pulverized coal injection systems (such as pulverized coal filters, fluidizers, etc.).
