2016 AIChE Spring Meeting – April 11-14, 2016 – Houston, TX

## Project Background

- Existing burners: conventional raw gas burner
- Average yearly NOx level: 244 ppmv [500 mg/Nm3]
- Heater roof tubes are 16.4 ft above furnace floor 
    - Existing burners were impinging on roof tubes causing hot spots and tube coking
- Poor combustion air distribution to burners

## GLSF Round Flame Minimum Emissions Burner

Chosen for its ability to achieve ultra-low NOx emissions while maintaining compact flame shapes and high flame stability on all fuels

## Conclusions

- Multi-Burner combustion testing was performed in Zeeco’s Testing Facility to accurately simulate on site conditions
- Burners were delivered to site and installed with Zeeco’s supervision
- On site burner performance testing was conducted and proved that the burners were meeting all required performance goals
- Further heater operation improvements can be performed to improve the burner performance even further
