Steel stack7/7/2023 ![]() In 1995, however, after a nearly 120-year history of steel production on the site, the plant closed its doors forever, leaving the region with a void that seemed impossible to fill. Navy, helping win two World Wars in the process. Source: National Museum of Industrial History, The Story Behind SteelStacksįor nearly a century, the Bethlehem Steel plant in Bethlehem served as the economic lifeblood of the community, employing tens of thousands of people while producing the steel that built our nation’s skyscrapers, bridges and even the U.S. ![]() Most of the iron was used in steelmaking, but a small percentage went to the iron and ingot mold foundries.Producing one ton of iron requires 3,366 pounds of ore, 1,676 pounds of coke and 724 pounds of limestone The furnaces each produced 2,600-3,000 tons of iron per day.The A furnace is the oldest, dating from 1915.From the west side of the "A" furnace (most westerly) to the east side of the "E" furnace it's approximately 1,100 feet - almost a quarter-mile!.The two largest furnaces are more than 230 feet tall.What many people may not realize is that these iconic structures are actually a series of five blast furnaces that were used in the iron making process at Bethlehem Steel for decades. When guests visit the SteelStacks campus, the first thing they usually notice are the towering 'stacks' after which the campus is named. Once the home plant of Bethlehem Steel, the second largest steel manufacturer in the nation, the site has been reborn through music and art, offering more than 1,000 concerts and eight different festivals annually. No attempt is made within this Standard to define the need or the methods to be used to consider these additional design considerations.SteelStacks is a ten-acre campus dedicated to arts, culture, family events, community celebrations, education and fun. In addition, the materials of construction referenced in this Standard may not be allowed for use with flammable gases under pressure per ASME B31.3 and Section VIII of the ASME BPVC materials suitable for pressure containment of flammable gases are listed in these codes. For stacks containing combustible gases under pressure such as flare stacks and flammable vents, additional design considerations must be addressed, including design for internal pressure, design for internal deflagration pressure, and compatibility with adjoining piping design that is in accordance with piping and/or vessel design codes such as ASME B31.3 and Section VIII of the ASME Boiler and Pressure Vessel Code. Although many of the topics within these guidelines may be used for all stacks, this Standard is intended to provide design guidelines for stacks containing non flammable gases such as combustion exhaust gases at low internal pressures. It outlines areas requiring maintenance and inspection following initial operation. It emphasizes the important areas regarding fabrication and construction. It gives the requirements for climbing and access based upon current Occupational Safety and Health Administration (OSHA) standards. It gives the requirements for lighting and lightning protection based upon existing building and federal codes. It gives guidelines for the selection of material, linings, and coatings. It emphasizes what consideration must be taken for wind- and seismic-induced vibrations. ![]() It outlines the consideration which must be made for both the mechanical and structural design. This Standard covers many facets of the design of steel stacks. The stack may be supported on a foundation or from another structure. It also applies to steel stacks that are guyed, or to certain aspects of tower stacks. It applies to both single-and multiple-walled steel stacks, either of which can be lined or unlined. ![]() The following Standard applies to steel stacks that is, those stacks where the primary supporting shell is made of steel. ![]()
