Abstract

The present technology is generally directed to methods of decarbonizing coking ovens, and associated systems and devices. In some embodiments, a method of operating and decarbonizing a coking oven can include inserting a charge of coal into the coking oven and heating the coal. The method can further include removing at least a portion of the charge, leaving behind coking deposits in the coking oven. At least a portion of the deposits can be continuously removed from the coking oven. For example, in some embodiments, at least a portion of the deposits can be removed each time a new charge of coal is inserted in the coking oven.
