Aluminized Steel Burner

Product Overview

Our custom aluminized steel burners are engineered for OEM gas-fired heating systems, including residential boilers, commercial water heaters, and heavy-duty cooking equipment. Fabricated from hot-dip aluminized carbon steel, these burners withstand continuous operating temperatures up to 450 degrees C while resisting the acidic condensates and sulfur compounds produced during natural gas and propane combustion.

We supply custom-built tubular, stamped, and ribbon burners manufactured strictly to customer CAD specifications, matching exact heat release rates, manifold pressures, and combustion chamber geometries.

Key Features

Optimal Thermal Efficiency

Precision-punched burner ports ensure uniform flame distribution and stable primary and secondary aeration.

Corrosion Resistance

The silicon-aluminum alloy coating forms a dense metallurgical barrier against flue gas condensate.

Structural Rigidity

Die-formed channels and reinforced seams prevent thermal warping during rapid ignition cycles.

Low Emissions Profile

Laser-controlled port geometries minimize CO and NOx formation, supporting clean combustion.

Manufacturing Process

Blanking & Coil Slitting: High-precision blanking ensures raw material flatness and edge cleanliness.

Multi-Station Stamping: Progressive dies shape the burner halves, venturi tubes, and mounting brackets in a single setup.

Port Piercing: High-speed CNC punching creates burr-free flame ports with tight pitch tolerances.

Seaming & Welding: Automated TIG or resistance seam welding ensures a gas-tight internal chamber under operational pressure.

Forming Calibration: Hydraulic straightening ensures zero angular distortion prior to final assembly.

FAQ

Q: What is the maximum operating temperature for aluminized steel burners?

A: Aluminized steel burners maintain structural integrity and oxidation resistance up to 450 degrees C (842 degrees F). Beyond this threshold, the iron-aluminum alloy layer degrades rapidly, accelerating substrate oxidation. For applications exceeding 500 degrees C, we recommend switching to stainless steel grades (such as 430 or 304).

Q: How do you prevent burrs during the burner port punching process?

A: We utilize custom, high-tolerance tungsten carbide progressive dies maintained through regular optical tool inspection. Punching clearance is strictly controlled relative to the material thickness (0.8 mm to 2.0 mm) to ensure clean, burr-free interior ports, eliminating flame distortion and premature carbon buildup.

Q: What is the typical lead time for custom tooling and prototype samples?

A: Standard custom prototype development takes 15 to 20 business days from final drawing approval and tooling kick-off. Mass production lead time typically ranges from 30 to 45 days, depending on order volume and material availability.

Q: Can these burners run on both Natural Gas (NG) and Liquefied Petroleum Gas (LPG)?

A: Yes. However, because NG and LPG have different Wobbe indices and stoichiometric air-fuel ratios, the total port area and venturi air-entrainment design must be optimized for your specific gas type during the engineering phase.

Q: What kind of quality documentation is provided with each shipment?

A: We supply a full Material Test Report (MTR) covering steel chemical composition and coating weight (ASTM A463 standards), along with dimensional inspection reports and 100% pressure leak test certificates per lot.

Q: How do you protect the burners from corrosion during international ocean freight?

A: Burners are treated with a light, anti-corrosive protective film (if required), packed in custom-molded moisture-barrier packaging or heavy-duty corrugated cartons with VCI (Volatile Corrosion Inhibitor) film, and secured on fumigation-free wooden pallets.
