HTS Krom Schroder Direct Fired Burners – Annular Excess Air
Need help selecting your product?
The Honeywell Eclipse Annular Excess Air (AEA) burner is designed for applications requiring precise control of combustion and low NOx performance across a wide operating range. Its annular design allows for high excess-air operation, providing uniform heat distribution, improved temperature control, and reduced emissions for process heating, furnaces, and ovens.
Features & Benefits
- Capable of operating with up to 300% excess air for extremely lean combustion.
- Produces uniform heat distribution and excellent temperature control.
- Low NOx and CO emissions through optimized air/fuel mixing design.
- Wide turndown ratio for flexible process control.
- High-velocity flame ensures efficient heat transfer and stability.
- Compact design suitable for retrofit or new installations.
- Compatible with natural gas, propane, and mixed gases.
