In the late 19th century, brick beehive ovens were developed, which allowed more control over the burning process. [ 6 ] The number of beehive ovens between 1870 and 1905 skyrocketed from about 200 to almost 31,000, which produced nearly 18 million tons of coke in the Pittsburgh area alone. [ 7 ]
These were the invention of the hot blast in iron-smelting and the introduction of the beehive coke oven. The use of a blast of hot air, instead of cold air, in the smelting furnace was first introduced by Neilson in Scotland in 1828. [9] The hearth process of making coke from coal is a very lengthy process. [citation needed]
Coke has a much higher temperature point than regular coal so it was preferred for use in the mills. [3] [4] [5] Each coke oven is about 12 feet in diameter and 6 to 7 feet in height with the capacity to hold two to three tons of coal each. While still using 100 ovens, Leetonia Coal & Iron would process 250 tons of coal into coke per day.
This was traditionally done in rudimentary beehive ovens on-site at coal mines. In 1910s, the industry began to prefer by-product ovens. In 1910s, the industry began to prefer by-product ovens. These more advanced ovens capture a variety of industrially useful chemicals released by the coking process, like coal tar , ammonium sulfate and benzole .
Using beehive coke ovens for coke production was a common practice for many years. However, advances in coke production technology meant beehive coke ovens technology was outdated by the early 1900s. Despite this, beehive coke ovens continued to be built in the Ipswich coal fields well into the mid twentieth century.
The Elkins Coal and Coke Company Historic District is a historic industrial site near the crossroads village of Bretz in Preston County, West Virginia.It is the site of the last major coke manufacturing facility to use beehive ovens, and was a major industrial site in northern West Virginia in the first half of the 20th century.

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.
