康乃狄克州東迦南的貝克利鼓風爐
地方性遺產
照片中的爐子是一陣貨真價實的鼓風爐。鼓風爐利用氣流來增進氧化作用。
鼓風爐底面有一個形似鎔爐的爐床，中間區域則稱為爐膛，它是一個直立的豎井(煙囪)，從爐膛向上延伸，直至爐子頂端，然後就是爐頂了。爐膛是鼓風爐最炙熱的部分，熔化的鐵會流到底部的爐床，而爐床表面的閥門孔，可將熔鐵排出，更高處的爐渣(渣滓)孔，則是用來移除雜質的混合物。
約翰亞當貝克利(John
Adam Beckley)於1847年時，興建了這座鼓風爐，用來鑄造生鐵
。生鐵是一種未經加工的鐵質，可提煉成鋼或熟鐵。1918年，使用了72年後，貝克利鼓風爐正式關閉。
1978年，東迦南的貝克利鼓風爐正式列入國家歷史古蹟管理處
。為保存這個煙囪，康乃狄克州在1946年時買下這座鼓風爐，但直到1999年才進行修復工程。爐床整個重建後，切除了其中一部分，以便讓遊客入內觀賞；這個鼓風爐是鐵傳統小徑上的顯著景點，這條小徑橫跨康乃狄克州的西北地區、紐約及麻州。
The furnace in the picture is a blast, literally. A blast furnace increases combustion with a blast of air.
Blast furnaces contain a hearth at the bottom that is shaped like a melting pot; a middle zone, called a bosh, a vertical shaft (the stack) that extends from the bosh to the top of the furnace; and the furnace top. The bosh is the hottest part of the furnace. Molten iron gathers in the hearth, which has a tap hole to draw off the molten iron and, higher up, a slag (residue) hole to remove the mixture of impurities.
John Adam Beckley built this furnace in 1847 for the production of pig iron, a crude kind of iron that is refined to produce steel or wrought iron. In 1918, after 72 years of operation, the Beckley Furnace closed.
In 1978, the Beckley Blast Furnace in East Canaan, Connecticut, was put on the National Register of Historic Places. Connecticut bought the furnace in 1946 with the intent of preserving the stack but didn't restore it until 1999. The hearth has been completely rebuilt with a cutaway section for visitor viewing. The blast furnace is a significant attraction on the Iron Heritage Trail in Northwestern Connecticut, New York, and Massachusetts.
