Method of and apparatus for charging coal into a coke oven chamber

摘要

Coke is charged into a coke oven chamber by positioning a filling hopper over an opening in the roof of the chamber and evacuating the chamber. A filling tube is lowered from the hopper to the bottom of the chamber and coal is fed from the hopper through the filling tube into the chamber while gas is evacuated from the latter during the filling. The filling tube is raised as the chamber is filled with coal through the tube and the velocity with which the tube is raised is controlled as a function of the subatmospheric pressure generated in the chamber by the evacuation of gas therefrom. Alternatively, the subatmospheric pressure generated in the chamber is controlled as a function of the velocity with which the tube is raised.
