Component Specifications

Definition
A precision-engineered component designed to introduce and distribute gas into a fluidization chamber with controlled velocity and direction, creating optimal fluidization conditions for solid particles. It features specific geometry to minimize pressure drop while ensuring uniform gas distribution across the chamber cross-section.
Working Principle
The nozzle converts high-pressure gas into a controlled, high-velocity stream that enters the fluidization chamber. The geometry (typically convergent-divergent or multi-orifice design) creates turbulent mixing at the particle bed interface, initiating and maintaining fluidization by balancing gas momentum with particle weight and drag forces.
Materials
Stainless steel 316L (ASTM A240), Inconel 625 for high-temperature applications, or ceramic-lined steel for abrasive environments. Surface finish: Ra ≤ 0.8 μm. Maximum operating temperature: 800°C. Pressure rating: 10-50 bar.
Technical Parameters
  • Spray Angle 15-90 degrees
  • Gas Velocity 20-100 m/s
  • Pressure Drop 0.1-2.0 bar
  • Connection Type Flanged (ANSI/ASME B16.5) or threaded (NPT)
  • Orifice Diameter 10-100 mm
  • Flow Coefficient (Cv) 5-200
Standards
ISO 5167, DIN 1952, ASME B31.3

Frequently Asked Questions

What is the purpose of the gas inlet nozzle in a fluidization chamber?

The gas inlet nozzle controls the introduction and distribution of gas into the fluidization chamber, creating optimal conditions for solid particle fluidization through controlled velocity, direction, and distribution patterns.

How does nozzle geometry affect fluidization performance?

Nozzle geometry determines gas velocity profiles, pressure drop, and distribution uniformity. Convergent-divergent designs maximize velocity while minimizing pressure loss, while multi-orifice designs improve distribution uniformity across larger chamber cross-sections.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
