Component Specifications

Definition
The burner head, also known as quarl, is a critical combustion chamber component in industrial burners that facilitates the mixing of fuel and oxidizer (typically air), provides flame stabilization through aerodynamic or geometric means, controls flame shape and direction, and ensures complete combustion with minimal emissions. It serves as the interface between the burner assembly and the combustion process, designed to withstand extreme thermal conditions while maintaining structural integrity.
Working Principle
The burner head operates on principles of fluid dynamics and combustion science. It creates turbulence or controlled flow patterns to mix fuel and air thoroughly, utilizes bluff bodies, swirl generators, or refractory surfaces to create recirculation zones that anchor the flame, and shapes the combustion zone to optimize heat transfer while preventing flame impingement on surrounding materials. The quarl geometry controls flame expansion and radiation characteristics.
Materials
High-temperature alloys (Inconel, Hastelloy), refractory ceramics (alumina, silicon carbide), stainless steels (310, 316), or composite materials with thermal barrier coatings. Material selection depends on operating temperature (typically 800-1600°C), fuel type, and thermal cycling conditions.
Technical Parameters

Frequently Asked Questions

What is the difference between burner head and quarl?

The burner head typically refers to the entire assembly including mixing and flame stabilization elements, while quarl specifically denotes the refractory-lined combustion chamber portion that shapes and contains the flame.

How often should burner heads be inspected?

Industrial burner heads should be inspected monthly for surface cracks, erosion, or deformation, with comprehensive maintenance every 6-12 months depending on operating hours and fuel type.

Can burner heads be used with different fuel types?

Some burner heads are designed for specific fuels, while multi-fuel models exist. Conversion requires checking compatibility of materials, orifice sizes, and mixing characteristics.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
