Coal charging telescope for filling coke ovens

A coal charging telescope for charging coke ovens, the coal charging telescope comprising:

• a connector device for fastening to a coal charging carriage;
• a charging telescope upper part which is suspended on pendulum elements;
• a charging telescope lower part which is suspended by way of further pendulum elements on a lifting device;
• and
• a first seal arranged between the charging telescope upper part and the connector device wherein the charging telescope lower part engages into the charging telescope upper part and is configured as a double-walled element which has an outer shell and an inner tube, wherein the connector device has a coal charging tube and a gas collecting space which adjoins the upper side of the charging telescope upper part with an outlet opening for discharging emissions, the coal charging tube extending in every functional position of the lifting device as far as into the region of the charging telescope lower part, and it being possible for emissions to be discharged through an annular space of the charging telescope lower part, which annular space is delimited by the outer shell and the inner tube, into the charging telescope upper part and from there into the gas collecting space of the connector device.
