Methods for decarbonizing coking ovens, and associated systems and devices

A method of decarbonizing a coke oven of coking deposits, the method comprising:

• processing a charge of coal in the coke oven, wherein the coke oven comprises a plurality of interior surfaces including a floor, a crown, and sidewalls that extend between the floor and the crown;
• removing the charge from the coke oven with a pushing ram that extends horizontally through the coke oven from a coal inlet end of the coke oven to a coke outlet end of the coke oven;
• and
• removing coking deposits from the coke oven, while removing the charge from the coke oven, by scraping at least a portion of the coking deposits with a scraper that is coupled to the pushing ram;
• the scraper including an elongated scraper body extending perpendicular to a length of the coke oven during scraping and a plurality of elongated scraper shoes coupled to the scraper body so that the scraper shoes are horizontally spaced apart from one another and extending parallel to the length of the coke oven during scraping.
