Computational Analysis on Effect of Ambient Swirling Flow on Combustion and Flame Development in Coal Burner Flames
석탄 연소로에서 버너주위 선회유동이 연소 및 화염발달에 미치는 영향에 관한 수치적 연구
Abstract
The present study aims to investigate quantitatively the hydrodynamic effect on combustion process of pulverized coal particles in large scale combustion chamber using computational analysis, with a general purpose computational fluid dynamics code. Burner hydrodynamics include swirl and turbulence intensity from the burner. To understand the phenomena which are difficult to observe how flow has influence on the combustion process, comparative effect of combustion related coal properties and hydrodynamics is evaluated on flame formation and development in burner flames.
