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 ...
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.
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 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 ...
Clairton Coke Works is a coking factory in Clairton, Pennsylvania (10 miles south of Pittsburgh) on the Monongahela River. Owned by U.S. Steel , it is the largest coking operation in North America or possibly the world.

The kiln body is made from a porous ceramic material lined with a coating that absorbs microwave energy. The microwave kiln is placed inside a microwave oven and heated to the desired temperature. The heating process is much less controlled than most modern electric kilns, as there is no built-in temperature monitoring.
