Mod motor for incoming<br />

combustion air<br />

UEL = Upper Explosive Limit<br />

LEL = Lower Explosive Limit<br />

Soot buildup<br />

Increased CO<br />

Decreased CO2<br />

Stack Temperature drop<br />

RICH flame<br />

LEAN flame<br />

Increased O2<br />

Decreased CO2<br />

Stack Temperature drop<br />

Turbulent Flame<br />

Laminar Flame<br />

To increase heat output, fuel velocity is<br />

increased. If sufficient combustion air is not<br />

provided, the flame will extinguish itself.<br />

The increase of both fuel and air velocity<br />

creates a turbulent flame.<br />
