Examples
A source of moving air, such as a fan or bellows, introduces additional air into the fire through the tuyere.
The major variation from the forge and fire just described is a 'back draft' where there is no fire pot, and the tuyere enters the hearth horizontally from the back wall.
The tuyere will enter the firepot at the bottom.
