Premixed VIStA Burner for an Once-Through Type Boiler
관류보일러를 위한 예혼합 VIStA 버너 개발
- Published : 2008.06.25
Abstract
Vortex Inertial Staged Air (VIStA) burner for an once-through type boiler has been restored to the original premixed type to reduce nitrogen oxide (NOx) emission. The premixed version yields additional de-NOx effect by 20 ppm. The flame is formed closer to the wall at the 1st stage combustion chamber compared with the non-premixed one. The combustion characteristics are more sensitive to the air distribution for the premixed type, which necessitates proper optimization.
