In the late 1800s, internal combustion gas engines were developed to burn gasses produced from blast furnaces, eliminating the need for fuel for steam boilers and increasing efficiency. Bethlehem Steel was one such company to employ this technology. [12] Huge, usually single-cylinder horizontal engines burned blast furnace gas.
Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide. The blast furnace operates as a countercurrent exchange process whereas a bloomery does not.
The engine was used to drive a 12,500 scfm fan to blow air into a blast furnace, and the design requirement was to use blast furnace exhaust gas as its fuel. The engine was modified so that all compressor discharge could be removed and fed to an external burner, from which products of combustion were returned to drive the turbine. Typically ...
News broke Wednesday that United States Steel plans to sell its two blast furnaces at Granite City Works to SunCoke Energy, Inc. If the sale goes through, it could cost the region approximately ...
Sloss Furnaces is a National Historic Landmark in Birmingham, Alabama in the United States.It operated as a pig iron-producing blast furnace from 1882 to 1971. After closing, it became one of the first industrial sites (and the only blast furnace) in the U.S. to be preserved and restored for public use.

A contract for the construction of four blast furnaces each outputting 500 tons per day, [13] totaling 22 ft × 85 ft (6.7 m × 25.9 m), was awarded to the Ritter-Conley Mfg. Co. in December 1906, which at the time had blast furnaces of the same dimensions under construction for Indiana Steel Co. at Gary. The new furnaces included modern skip ...
The original blast furnaces at Blists Hill, Madeley. In 1709, Abraham Darby I established a coke-fired blast furnace to produce cast iron. Coke's superior crushing strength allowed blast furnaces to become taller and larger. The ensuing availability of inexpensive iron was one of the factors leading to the Industrial Revolution. Before this ...
