Tuyere \Tu`y[`e]re"\, n. [F.; akin to tuyau a pipe; of Teutonic origin. Cf. Tweer, Tewel.] A nozzle, mouthpiece, or fixture through which the blast is delivered to the interior of a blast furnace, or to the fire of a forge. [Corruptly written also tweer, and twier.]

Tuy[`e]re arch, the embrasure, in the wall of a blast furnace through which the tuy[`e]re enters.


n. A nozzle or similar fixture through which the blast is delivered to the interior of a blast furnace, or to the fire of a forge


n. (alternative form of tuyere English)


A tuyere or tuyère (; ) is a tube, nozzle or pipe through which air is blown into a furnace or hearth.

Air or oxygen is injected into a hearth under pressure from bellows or a blowing 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 from French 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 are often water-cooled.

Usage examples of "tuyere".

World administration is handed by the Tuyere, a rotating board of three Optimen, who rule over the millions like a dark trinity of Fates.

The Survey Globe had been moved aside and the Tuyere occupied a position on the front bench center at the end of the hall.

The hot water that cooled the tuyeres came into it, some fifty yards up--a tumultuous, almost boiling affluent, and the steam rose up from the water in silent white wisps and streaks, wrapping damply about them, an incessant succession of ghosts coming up from the black and red eddies, a white uprising that made the head swim.
