A tuyere is a tube or pipe through which air is blown into a furnace or hearth.
Additional recommended knowledge
Air (or oxygen) is injected into a hearth under pressure from bellows or a blast engine or other devices. This causes the fire to be hotter in front of the blast than it would otherwise have been, enabling metals to be smelted or melted or made hot enough to be worked in a forge. This applies to any process where a blast is delivered under pressure to make a fire hotter.
The term (like many technical terms relating to ironmaking) was introduced to England with the new technology of the blast furnace and finery forge in around 1500, and was sometimes anglicised as tu-iron.
Following the introduction of hot blast, tuyeres were often water cooled.
