Abstract

A correlation between an air inflow velocity and $NO_x$ emission is investigated numerically. The area of a swirl premixed burner is controlled geometrically to increase or decrease an air inflow velocity. When an air velocity increases, mixedness at the burner exit is improved and NO emission at the liner exit is reduced. Although the area of an air slit is the same, NO emission shows discrepancy due to difference of air slit shapes.
