The invention relates to a method and a device for cleaning the door of a coke oven, said door comprising a sealing edge and a membrane that is attached to the door panel of the coke oven. According to said method, cleaning tools comprising jet nozzles, which are supplied with a flow medium at high pressure, are situated and displaced back and forth in the region between the sealing edge and the door panel of the coke oven, in such a way that the interior surface of the membrane and the sealing edge are cleaned. The coke oven door is cleaned directly after the coke oven chamber is opened, by at least one jet nozzle element, which is supplied with compressed air and is displaced along the sealing edges. The jet nozzles are oriented in such a way that the air hits the surface to be cleaned at an acute angle.

Selon le procédé de l'invention, des instruments de nettoyage sollicités par un fluide d'écoulement haute pression et munis de busettes de sablage sont placés et mus en un mouvement de va-et-vient dans la zone située entre l'arête d'étanchéité et la plaque de porte de four à coke, de manière à nettoyer la surface intérieure de la membrane et l'arête d'étanchéité. La porte de four à coke est nettoyée directement après l'ouverture de la chambre de carbonisation en déplaçant au moins un élément de buse de sablage sollicité par de l'air comprimé le long des arêtes d'étanchéité et en orientant les buses de sablage de sorte que l'air frappe la surface à nettoyer à angle aigu.
