Q: Please define turndown ratio and tell what the advantages are for a higher turn down.
Rajeev Bansal, Delhi
A: Turndown ratio is the ratio of maximum fuel input rate to minimum fuel rate of a variable input burner. Traditionally burners on firetube boilers operate in the 4:1 turndown ratio range depending on fuel and size.
Advantages of high turndown burners include:
- Reduction of standby losses
- Limiting thermal cycling
- Saves wear and tear of burner components
Disadvantages include:
- Initial cost and complexity
- Requires more maintenance
- Limitations of Boiler/burner system
The limitations include fuel/air mixing requirements, material temperature issues, flame shape characteristics, flow control limitations and pressure vessel limitations.
