Secondary combustion
The swirl boosts efficiency
The secondary combustion chamber (burnout chamber) is located above the main combustion zone of the grate. A construction at the inlet allows injection of secondary combustion air or recirculated flue gas. The tangential arrangement of nozzles produces a swirling flow in the chamber, promoting uniform mixing and uniform combustion-gas temperature.
Your advantages:
- Better burnout of combustion gases and fly ash
- Lower CO emissions
- Optimized inlet flow to SNCR denitrification
