Reliable flame stability starts at the burner core. Flameholders play a critical role in maintaining consistent ignition, stable combustion, and proper flame shape inside asphalt plant burners. Motion Engineering stocks a range of flameholder assemblies designed for specific burner models used throughout the aggregate drying industry.

These components are built to withstand high temperatures, variable fuel conditions, and continuous operation in demanding plant environments.

How Flameholders Support Stable Combustion

A flameholder helps anchor and stabilize the flame at the burner face. Creating controlled turbulence and recirculation of hot gases, it allows the burner to maintain a steady flame across a wide operating range. When flameholders wear or become damaged, plants often experience flame instability, ignition issues, or reduced combustion efficiency.

Replacing a worn flameholder restores proper burner performance and helps protect surrounding burner components from uneven heat exposure.

Designed for Open-Fired, Multi-Fuel Burner Applications

These flameholder assemblies are commonly associated with Hauck StarJet and similar open-fired multi-fuel burners, where flame stabilization and wide turndown capability are required. When reviewing burner parts diagrams, these flameholders frequently appear as serviceable components within those burner assemblies.

Because flameholders are model-specific, correct part selection is important to ensure proper fit, flame shape, and burner performance.

Signs It’s Time to Replace a Flameholder

Running with worn or damaged flameholders can lead to:

  • Flame instability or flame-out conditions
  • Poor combustion efficiency
  • Uneven heat distribution inside the drum
  • Increased stress on other burner components
  • Unplanned shutdowns during production

Installing the correct flameholder assembly helps restore stable combustion and supports consistent burner operation across changing production rates.
