What does a coke oven make?
The Coke Oven is a 3x3x3 structure built similarly to the Blast Furnace. It is used to produce Coal Coke (used as an alternative to Charcoal in the Blast Furnace) and Creosote Oil. The structure is made by placing Coke Oven Bricks in a 3x3x3 cube without the middle block.
What is a coke oven plant?
Coke is used in Blast Furnace (BF) both as a reductant and as a source of thermal energy. It involves reduction of ore to liquid metal in the blast furnace and and refining in convertor to form steel. The various stages of the steel plant is described below. A schematic diagram of Coke Oven Battery is given in Fig.
What was a coke oven used for?
The coke ovens were used to convert the coal mined in the local area into industrial coke, a relatively clean-burning fuel used in the smelting of iron ore. In a process known as “coking,” coal was shoveled into an insolated beehive-shaped and ignited.
Are coke ovens still used?
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). Otherwise the volatile byproducts are burned to heat the coking ovens. This is an older method, but is still being used for new construction.
How do coke ovens work?
After heating up the coal into coke, the coke is then unloaded from the oven by a pusher machine. During the distillation process, a large amount of gas and smoke is generated, which, after purification, creates coke oven gas, and other by-products such as ammonia, tar, sulfur, naphthalene, and benzol.
How did old coke ovens work?
A worker known as a “scraper” leveled off the coal by reaching in through the door in the front of the oven. He did that so the coke would burn evenly. “The coal was loaded, or “charged”, into an oven that was between two hot ovens, so that the newly-charged oven could light itself by spontaneous combustion.
How did the old coke ovens work?

What are the hazards of working in a coke oven?
Hazard Summary. Exposure to coke oven emissions may occur for workers in the aluminum, steel, graphite, electrical, and construction industries. Chronic (long-term) exposure to coke oven emissions in humans results in conjunctivitis, severe dermatitis, and lesions of the respiratory system and digestive system.
Who are the people exposed to coke oven emissions?
Workers at coking plants and coal-tar production plants may be exposed to coke oven emissions. Occupational exposures can also occur among workers in the aluminum, steel, graphite, electrical, and construction industries.
What kind of cancer can you get from a coke oven?
Exposure to coke oven emissions increases the risk of lung cancer and, possibly, kidney cancer.
What are the different types of coke ovens?
Coke ovens can be classified into two basic types: those from which the volatile by-products are collected for subsequent use (by-product coke ovens) and those in which no attempt is made to recover by-products, apart from using some of the released volatiles as a heat source for the coking operation (nonrecovery coke ovens).
