Abstract
A method of charging a coke oven with coal includes the steps of charging coal in a coke oven chamber, whereby a heap of coal forms in the chamber; and leveling the heap of coal, where the leveling step includes: introducing a blasting end of a blasting pipe into the heap of coal, the blasting pipe being in communication with a pressurized gas storage vessel configured to release gas blasts; releasing at least one gas blast through the blasting end in the heap of coal in order to cause a leveling thereof; removing the blasting pipe from the chamber.
Claims12
Coke oven comprising:
- at least one coke oven chamber having a roof;
- and
- a device for leveling a heap of coal, said device comprising:
- a storage vessel having an outlet, said storage vessel being filled with a volume of pressurized gas and configured to instantly release said volume of pressurized gas through said outlet to create gas blasts;
- a blasting pipe in fluid communication with said outlet, said blasting pipe having a connection port and a blasting end, said connection port being axially remote from said blasting end and being connected with said storage vessel;
- at least one blasting opening at said blasting end of said blasting pipe through which a blast of compressed gas is released into a heap of coal, an impact force of the blast causing collapsing and leveling of the heap;
- and
- a manipulator configured for moving said blasting pipe, through said roof, between a rest position and a working position, in which said blasting end of said blasting pipe is positioned in a heap of coal.
