Air Compensator (Air Compensation Regulator) DN100 / DN25 PN16

The Air Supplement Regulator (Air Supplement Device) DN100/DN25 PN16 is a key piece of equipment in blast furnace pulverized coal injection and pneumatic conveying systems. It is primarily used for dense-phase conveying of pulverized materials such as coal powder, achieving stable and efficient solid-gas mixing by regulating the supplemental air volume. Below are its core parameters and features:

Technical Parameters
Nominal Diameter: DN100 (main pipe), DN25 (supplemental air pipe)
Design Pressure: PN16 (1.6 MPa)
Applicable Medium: Pulverized coal + nitrogen/air, design temperature 100°C

Regulation Method: Precise air volume control via the air supplement regulating valve or air volume adjustment bolt
Structural Features
Dual-Sleeve Design: Central pipe conveys coal powder, outer annular pipe supplements air, with optimized jet angle for enhanced mixing.
Wear-Resistant Material: Uses metallurgically 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 an air supplement regulating seat and bolt, supporting stepless air volume adjustment.
Application Advantages
Stable Conveying: Disrupts material column formation, enabling long-distance dense-phase conveying.
Energy Saving and Environmental Protection: Reduces gas waste and minimizes pipeline wear.
Compatibility: Compatible with pulverized coal injection system components (such as coal powder filters, fluidizers, etc.).
