Definition of tuyère in US English:



  • A nozzle through which air is forced into a smelter, furnace, or forge.

    • ‘The tuyère was just a hollow tube made of clay, but I sent it to the British Museum and they analysed it and said it was part of a Bronze Age furnace, the mouth of the bellows.’
    • ‘This ensures that the laden fluid is evenly distributed around the casing and therefore enters the tuyeres from all directions.’
    • ‘Artifacts discovered here included potsherds, some tuyeres, a clay smoking-pipe, oval-shaped pieces of chalk, shells of a variety of saltwater shellfish, and mammalian bones.’
    • ‘For making steel castings a modification known as a Tropenas converter is used, in which the air impinges on the surface of the metal from side tuyeres instead of from the bottom.’
    • ‘In particular, tuyeres in the furnace became blocked with slag.’


Late 18th century: French, from tuyau ‘pipe’.
