What is a Venturi tube used for in a gas burner?

A Venturi tube helps mix gas and primary air before combustion. Depending on the application, inlet tubes can be manufactured with or without a Venturi feature to achieve the desired burner performance.

How are Stealth Manufacturing's custom gas inlet tubes customized?

Stealth Manufacturing customizes inlet tubes based on each application's requirements, including material selection, tube diameter, shutter configuration, flange or non-flange design, and whether a Venturi feature is incorporated into the assembly.

What materials are available for custom gas inlet tubes?

Stealth Manufacturing produces custom gas inlet tubes using stainless steel and aluminized steel. Material selection is based on the specific performance and application requirements of the burner assembly.

What is the purpose of a shutter on a Venturi tube?

A shutter allows precise adjustment of the primary air entering the burner and typically positions the gas orifice to maintain proper concentricity. This helps achieve the desired air-to-gas mixture for the application.

What manufacturing capabilities does Stealth Manufacturing offer for custom inlet tubes?

Stealth Manufacturing supports custom inlet tube production with in-house capabilities including CNC machining, tube bending and threading, laser cutting, laser porting, stamping, turret punching, brake press forming, drilling, robotic and hand welding, and assembly with hardware insertion.

What other gas burner components does Stealth Manufacturing manufacture?

In addition to custom gas inlet tubes, Stealth Manufacturing manufactures tubular burners, seamless pan burners, gas manifolds, gas orifices, and other atmospheric gas burner components to support complete burner assemblies.

More than a fabrication shop, Stealth Manufacturing is a full-service partner for gas burner products and complete assemblies.

What is a Gas Inlet Tube (Venturi Tube)?

Gas inlet tubes channel gases into the burner assembly. They regulate gas flow by pulling in primary air and premixing the air and fuel, balancing the flow of the gas/air mixture for even, consistent combustion. Designing inlet tubes with the right features and specifications delivers long-term product reliability, combustion efficiency, and burner performance.

Why Proper Inlet Tube Design Matters in a Gas Burner Assembly

Inlet tube design is essential for the performance and efficiency of gas burner assemblies. Because they control the fluid and airflow dynamics of the assembly, these components should deliver consistent combustion and stable flame characteristics for improved thermal efficiency. Other critical factors that proper inlet tube design for burner assemblies ensures:

Reduced emissions
Reliable ignition
Proper gas velocity
Reduced flashback risk
Long-term product reliability
