2ry air
3ry air

 Pulverized coal is separated to dense layer and thin zone by swirler.
 Outer flame is composed of dense PC while flame center is lean.
 Combustion air, 2ry and 3ry air are fed to outer flame, which makes burner flame
stable.
 3ry air is fed swirling, which uniforms combustion air distribution.
