Abstract
A decarbonization apparatus for a coking chamber of a coke oven, which comprises a lance connected to an oxygen-containing gas pressure source, and a support for supporting and inserting the lance into the coking chamber. The lance has at least one nozzle projecting therefrom in such manner that the gas ejected therefrom flows almost parallel to the side wall of the coking chamber.
