康涅狄格州东迦南的贝克利鼓风炉
地方性遗产

照片中的炉子是一阵货真价实的鼓风炉。鼓风炉利用气流来增进氧化作用

鼓风炉底面有一个形似镕炉的炉床,中间区域则称为炉膛,它是一个直立的竪井(烟囱),从炉膛向上延伸,直至炉子顶端,然后就是炉顶了。炉膛是鼓风炉最炙热的部分,熔化的铁会流到底部的炉床,而炉床表面的阀门孔,可将熔铁排出,更高处的炉渣(渣滓)孔,则是用来移除杂质的混合物。

约翰亚当贝克利(John Adam Beckley)1847年时,兴建了这座鼓风炉,用来铸造生铁 。生铁是一种未经加工的铁质,可提炼成钢或熟铁。1918年,使用了72年后,贝克利鼓风炉正式关闭。

1978年,东迦南的贝克利鼓风炉正式列入国家历史古迹管理处 。为保存这个烟囱,康涅狄格州在1946年时买下这座鼓风炉,但直到1999年才进行修复工程。炉床整个重建后,切除了其中一部分,以便让游客入内观赏;这个鼓风炉是铁常规小径上的显着景点,这条小径横跨康涅狄格州的西北地区、纽约及麻州。


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.
