The tuyere, which is fitted to a wooden conduit of square section that runs along the back of the masonry, is placed in the axis of the cadinhes and enters the masonry at a few centimeters from the bottom in such away that its nozzle comes just flush with the surface of the refractory lining.

Air is forced through this hole, called a "tuyere" (Figure 48) by means of. From Wordnik.com. [Oxy-Acetylene Welding and Cutting Electric, Forge and Thermit Welding together with related methods and materials used in metal working and the oxygen process for removal of carbon] Reference
Limbo yielded "sherds of the Early Iron Working (EIW) tradition, several tonnes of slag, and tuyere fragments.". From Wordnik.com. [Societies, Religion, and History: Central East Tanzanians and the World They Created, c. 200 BCE to 1800 CE] Reference
The air necessary for the combustion is sucked through the interior of the nozzle, H, which is in front of the tuyere. From Wordnik.com. [Scientific American Supplement, No. 623, December 10, 1887] Reference
It will be seen that the current of steam can be regulated by moving the tuyere, D, from or toward the eduction orifice. From Wordnik.com. [Scientific American Supplement, No. 623, December 10, 1887] Reference
The harder the air is driven into the fire above the tuyere the more oxygen is furnished and the hotter the fire becomes. From Wordnik.com.

A section of the bellows forms the portion to the right of Fig. 1, showing tuyere forming the connection between bellows and furnace. From Wordnik.com. [Scientific American Supplement, No. 561, October 2, 1886] Reference
This arrangement prevents the tuyere from getting befouled by scoriæ during the operation of the furnace and thus interfering with the wind. From Wordnik.com. [Scientific American Supplement, No. 430, March 29, 1884] Reference
Two such bellows are placed side by side, a thin bamboo tube attached to each, and both entering the one tuyere; and so by jumping on each bellows alternately, the workman keeps up a continuous blast. From Wordnik.com. [Scientific American Supplement, No. 561, October 2, 1886] Reference
At the back part there is a small aperture for the introduction of the tuyere, and which permits, besides, of the nozzle of the latter being easily got at so as to see whether the blast is working properly. From Wordnik.com. [Scientific American Supplement, No. 430, March 29, 1884] Reference
The bloom forms gradually beneath the nozzle of the tuyere, in the center of the bed of sand and charcoal, and is surrounded on every side with an exceedingly pasty mass, formed of silicates of iron and manganese (Fig. 7). From Wordnik.com. [Scientific American Supplement, No. 430, March 29, 1884] Reference
This tuyere is usually made of the same material as the furnace -- namely, of a sandy soil; worked by hand into the required form and sun-dried; but sometimes no other tuyere is employed than a lump of moist clay with a hole in it, into which the bamboo pipes communicating with the bellows are inserted. From Wordnik.com. [Scientific American Supplement, No. 561, October 2, 1886] Reference
There are two apertures at the base of the furnace; one in front, about 1 ft. in height, and rather less in width than the internal diameter of the furnace, through which, when the smelting of one charge is finished, the resulting mass of spongy iron is extracted, and which during the smelting is well plastered up, the small conical tuyere being inserted at the bottom.

The invention of the tubular air-vessels and the water-tuyere belongs, we believe, to Mr. John Condie, sometime manager of the Blair Iron Works. From Wordnik.com. [Industrial Biography]
Great care should be exercised properly to design them so that a minimum amount of the cold tuyere will be in contact with the interior of the furnace, and all interior portions possible should be covered by the bricks. From Wordnik.com. [The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel] Reference
Water-cooled, tuyere openings, as mentioned above, which support brick side-walls of the furnace, have proved successful for coal furnaces used for forging machine and drop-hammer heating, since they permit a great amount of work to be handled through their openings without wearing away as would a brick arch. From Wordnik.com. [The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel] Reference
The furnace once lighted and started may be kept running day and night continuously for days, months, or years, if desired; but if it becomes necessary to stop at any time, the tuyere pipes may be removed and the holes all stopped with clay, so as to entirely shut off the supply of air, and it will then hold in fire for many days, and will be in readiness to start again at any time the pipes are replaced and the blast turned on.
