- •
Reactive flow experiments at various loads with deep air staging were conducted.
- •
The NOx emission decreases to some extent with a decreasing boiler load.
- •
After retrofit excellent boiler performance is achieved at various loads.
- •
NOx content decrease with significant reduction proportion compared with before.
- •
Numerical calculation results are consistent with the industrial experiment results.
