Scranton in Lackawanna County, Pennsylvania — The American Northeast (Mid-Atlantic)
Supplying the Blast
A strong steady blast of air was essential for the furnace to operate properly. The air was carried into the furnace by three pipes called tuyeres (pronounced twee AIRS), which passed through the archways in the rear and on the sides of each furnace, just above the hearth. Due to the intense heat, tuyere pipes were usually made of cast iron and encased in a water cooled jacket.
Initially, the power necessary to operate the blast machinery was generated by an overshot whaterwheel located on Roaring Brook. Built in 1841 by Thomas P. Harper, the wheel turned a connection shaft, which caused two reciprocating blowing tubs to raise and fall, thus forcing air into the furnaces.
