Product Introduction


Lost Wax Casting Burner Parts are high-precision components designed for complex geometries and extreme operating conditions in industrial combustion systems. Manufactured from heat-resistant alloys such as 310S (UNS S31000), Incoloy 800H (UNS N08810), or nickel-based superalloys via investment casting, these parts—including nozzles, flame holders, and mixing chambers—feature intricate internal channels and thin-wall structures unattainable by traditional machining.


Subjected to rigorous NDT (non-destructive testing) and heat treatment, the parts meet ASTM A351 and ASME BPVC Section III standards, ensuring reliability in temperatures up to 1,400°C (2,552°F) and pressures up to 50 bar (725 PSI).


Product Advantage


The honeycomb structure helps maintain flame stability and prevents quenching or fluctuations. It requires the use of high-temperature and corrosion-resistant materials, as well as precise dimensional accuracy in the manufacturing process.

Complex Geometry Capability: Lost wax casting enables features like multi-louver nozzles, helical flow channels, and porous flame stabilizers, optimizing fuel-air mixing for reduced emissions and improved combustion efficiency.

High-Temperature Performance: Incoloy 800H parts resist carburization and oxidation in cyclic thermal environments, while 310S offers cost-effective performance in continuous high-temperature applications (≤ 1,200°C/2,192°F).

Precision Surface Finish: As-cast surfaces (Ra ≤ 3.2μm) require minimal post-machining, with optional electroplating or thermal spraying for enhanced wear resistance in particle-laden gases (≤ 100μm diameter).

Material Optimization: Custom alloy formulations (e.g., increased tungsten for creep resistance) are available for specialized applications, with trace element analysis ensuring compliance with nuclear and aerospace purity standards.


Product Uses


It ensures even fuel distribution, improves air-fuel mixing efficiency, enhances combustion, stabilizes the flame, and reduces noise.


Product Application


The burner component, made of high-temperature corrosion-resistant materials, is durable and suitable for harsh environments. These components are widely used in industrial burners, household appliances, and emission control systems to improve combustion efficiency and reduce pollutant emissions.

Power Generation Turbines: Used in gas turbine combustors for aircraft and industrial power plants, with Inconel 718 parts enduring high-frequency thermal cycling and centrifugal forces.

Steel & Glass Manufacturing: Deployed in reheating furnaces and glass melting tanks, where 310S nozzles resist scaling from iron oxide and molten glass splatter.

Waste-to-Energy Plants: Integral to municipal waste incinerators, with flame holders made from corrosion-resistant alloys that withstand chlorine-induced pitting and ash abrasion.

Aerospace Auxiliary Power Units (APUs): Forms lightweight, high-strength components for compact burners, meeting FAA flammability requirements and operating in low-pressure, high-altitude environments.


FAQ


Q: What is the minimum wall thickness achievable with lost wax casting?

A: Standard processes achieve 1-2mm; advanced techniques allow down to 0.5mm for intricate cooling channels in aerospace burners.

Q: Can these parts be repaired after thermal fatigue?

A: Minor cracks can be repaired via laser welding and re-heat treatment; major damage requires replacement, with modular designs enabling quick part swapping.

Q: How are casting defects like porosity addressed?

A: 100% radiographic inspection and vacuum impregnation of minor voids ensure structural integrity, with critical parts undergoing helium leak testing for gas-tightness.
