Specifications
- NO emission
- {'zh': '270', 'en': '270'} ppmvd
- NO emission
- {'zh': '378', 'en': '378'} ppmvd
Advantages
Zero CO emission
No CO is detected in the combustion products under optimized air-staging conditions in both premixed and non-premixed modes.
Low NO emission
NO emission is as low as 270 ppmvd (at 6% O2) in premixed mode and 378 ppmvd (at 6% O2) in non-premixed mode.
Works in both modes
The axial air-staging strategy achieves zero CO and low NO emissions in both premixed and non-premixed combustion modes.
Applications
- Hydrogen-Ammonia Combustion：Provides a low-NOx combustion organization scheme for hydrogen-ammonia fuels, replacing traditional high-emission combustion methods.
- Low-NOx Burner：Can be directly used as design parameters for low-NOx burners to achieve zero CO and low NO emissions.
- Industrial Boiler：Provides air-staging parameters for ammonia co-firing in industrial boilers to reduce NOx and eliminate CO.
- Gas Turbine Combustor：Guides axial-staging design of gas turbine combustors to achieve low NOx and zero CO emissions.
