What does tuyere mean?
A tuyere is the opening or nozzle through which a blast furnace receives its forced air supply. In a blast furnace, iron ore, coke, and limestone are heated while a powerful stream of air enters through one or more tuyères, raising the temperature and accelerating combustion. The term is consequently associated with ironmaking, foundry work, and the high-temperature machinery of industrial metallurgy. Outside that context, it is rarely used; when the technical contrast matters, writers distinguish a tuyere from a general nozzle or pipe by identifying its role in directing the furnace blast. Its standard English plural is tuyères, although the accent may be omitted in typeset text. Though specialized, the word describes a vivid and important function: it names the confined opening through which immense volumes of air enter a furnace, making it useful vocabulary for discussions of steelmaking, combustion, and industrial history.
nounA tuyere is an opening or nozzle in a blast furnace through which air is forced under pressure to promote combustion.
- An opening or nozzle in a blast furnace through which the air blast enters.
"The blast enters the furnace through a tuyere and raises the temperature of the molten iron."
"Air is forced through the tuyere and into the furnace."
"The cast-iron tuyere plate must withstand extreme heat and continual exposure to the blast."
The standard plural retains the accent, though tuyeres is also common in English text without it.
"Several tuyères introduce the air blast into the furnace."
A tuyere is a furnace's air inlet—the narrow opening where a powerful blast feeds the fire.

Etymology of tuyere
The English word was borrowed in the 19th century from French tuyère, a term associated with tuyau, meaning a pipe or nozzle. The French word ultimately traces to Latin roots meaning pipe, placing tuyere in the wider family of European words that includes English tube, tub, and tubular. Its development from a general term for a pipe to a specifically metallurgical term reflects the specialized role it came to play in blast furnaces.
How tuyere is actually used
A specialized metallurgical term, chiefly associated with blast furnaces and ironmaking. In broader industrial usage, it can refer to a nozzle or passage that directs a blast, but the blast-furnace sense is dominant.
