Nozzle/Orifice Plate Component – Machinery and Equipment Manufacturing

Component Specifications

Definition

A nozzle/orifice plate is a critical fluid dynamics component installed in burner heads that precisely meters and controls the flow rate of fuel (gas or liquid) while creating optimal atomization patterns for efficient combustion. It features calibrated openings that convert pressure energy into velocity, ensuring proper fuel-air mixing and flame stability in industrial heating applications.

Working Principle

Operates on Bernoulli's principle and fluid dynamics - as fuel passes through the precisely engineered orifice, pressure drops while velocity increases, creating fine atomization. The geometry controls flow characteristics, spray angle, and droplet size distribution for complete combustion.

Materials

Stainless steel (AISI 304/316), Inconel, Hastelloy, Tungsten carbide, Ceramic composites for high-temperature applications; Material selection based on fuel type, temperature, and corrosion resistance requirements.

Technical Parameters

Tolerance ±0.01 mm
Spray Angle 15°-90°
Pressure Range 0.5-50 bar
Orifice Diameter 0.5-10 mm
Temperature Range -40°C to 1200°C
Flow Coefficient (Cv) 0.1-5.0

Standards

ISO 5167, DIN 1952, ASME MFC-3M

Frequently Asked Questions

What is the difference between a nozzle and an orifice plate in burner applications?

A nozzle typically includes both flow metering and atomization functions with specific spray patterns, while an orifice plate is primarily for precise flow measurement and control. In burner heads, they often combine both functions.

How often should burner nozzles be inspected and replaced?

Inspect every 3-6 months; replace every 12-24 months depending on fuel type, operating hours, and maintenance schedule. Signs of wear include irregular flame patterns and increased fuel consumption.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
