Each bank face had a oven door sill level platform for holding and cooling coke, above a RR track for shipping it. [4] Beehive coke ovens were batch processors. Given a hot oven, the coking cycle begins by adding coal from the top and leveling it to produce an even layer of about 60–90 centimetres (24–35 in) deep.
The coke oven is the central element of a coking plant. Horizontal ovens, which are the most commonly used (they are suitable for monitoring the various extraction stages), take the form of narrow compartments (approx. 50 cm wide), but several meters high and several meters deep. Modern compartments have a volume of up to 100 m3 (e.g. 0.5 × 6 ...
A coke oven at a smokeless fuel plant, Abercwmboi, South Wales, 1976. The industrial production of coke from coal is called coking. The coal is baked in an airless kiln, a "coke furnace" or "coking oven", at temperatures as high as 2,000 °C (3,600 °F) but usually around 1,000–1,100 °C (1,800–2,000 °F). [2]
The beehive-shaped brick ovens are approximately 8 feet (2.4 m) high and 12 feet (3.7 m) in diameter, covered with 6 inches (150 mm) of cement with a small hole on top. A protective 10 feet (3.0 m) high sandstone wall that faced the ovens was removed in the late 1940s, resulting in some erosion of the earth covering the ovens.
In 1916, U.S. Steel opened its Clairton Coke Works, a $18,000,000 by-product plant. [7] It was the first full by-product plant in the region and easily the largest in the United States with 1,500 ovens. [8] [9] The plant grew rapidly, adding hundreds more coke ovens built by Koppers.

Traditionally, construction has made use of manual labor such as tradesmen and subcontractors for tasks such as the installation of prefabricated elements. [6] In the industrialization phase, construction uses manufacturing processes and technology to perform off-site prefabrication, assembling building components off-site rather than at the point of installation.
The reconstructed building now houses the Coke Ovens Museum. [7] Along with the museum, ovens, and amphitheater, Dunlap Coke Ovens Park includes a coal mine replica with mining machinery on display, the ruins of the 1906 coal washer, a replica of the Dunlap depot, a caboose, and various park shelters. A hiking trail now follows the incline ...
