The steam locomotive exhaust system consists of those parts of a steam locomotive which together discharge exhaust steam from the cylinders in order to increase the draught through the fire. It usually consists of the blastpipe (or first stage nozzle), smokebox , and chimney , although later designs also include second and third stage nozzles.

A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel).
Increasing the velocity of steam exhaust tended to both accelerate airflow through the firebox and lift the smoke higher above the top of the chimney. By the 1830s, steam exhaust was directed through a contracted nozzle called a blastpipe, so as to achieve the desired velocity through the chimney. Pressure drop through the blastpipe nozzle was ...
