Abstract: The filling carriage for coke oven, comprises a filling container for coal, a filling telescope (3) for filling of coal in a furnace chamber (1) and a suction system (2) for exhaust of residue emission liberated between a telescope lower part (4) and a filling-hole frame (5). The filling carriage is processed on a cover of the oven chamber arranged in battery-wise manner. The telescope lower part of the filling telescope is lowered on the filling-hole frame of a filling hole of the furnace chamber under formation of gas-tight density connection for the filling-hole frame. The filling carriage for coke oven, comprises a filling container for coal, a filling telescope (3) for filling of coal in a furnace chamber (1) and a suction system (2) for exhaust of residue emission liberated between a telescope lower part (4) and a filling-hole frame (5). The filling carriage is processed on a cover of the oven chamber arranged in battery-wise manner. The telescope lower part of the filling telescope is lowered on the filling-hole frame of a filling hole of the furnace chamber under formation of gas-tight density connection for the filling-hole frame. The suction system has suction hood surrounding the telescope lower part of the filling telescope. The suction hood is lowered on the filling-hole frame and includes a circular suction chamber with the telescope part after lowering on the filling-hole frame. A cover tube is intended as suction hood arranged coaxially to the telescope lower part. The telescope lower part is arranged partly inside of the cover tube. The circular suction chamber is formed between the telescope lower part and the cover tube. A sealing surface for gas-tight lowering of the cover tube on the filling-hole frame is intended at an end of the cover tube facing towards the furnace chamber. The cover pipe together with the telescope lower part in the direction is lowered on the filling-hole frame and raised from the filling-hole frame. The cover tube and the telescope lower part are kinematically coupled. A corrugated tube compensator is intended for the compensation of length- and angle changes between the filling telescope and the cover tube. The compensator is connected with its upper end to the telescope lower part and its lower end to the cover tube. The suction system has a suction line for the connection at a suction device and/or a filter device. The suction line has a first line section arranged parallel to the filling telescope and to the cover tube. The first line section is connected to suction nozzles. The first line section has a stationary upper tube-piece arranged at the filling carriage and a telescope-like lower tube piece insertable and extendable in the upper tube piece. A further compensator is arranged between the suction nozzle and the lower tube-piece of the first line section. A common holder is intended for the telescope lower part and the lower tube piece. The telescope lower part and the tube piece are movably led in the holder in vertical direction. The cover tube has a suction opening in the connection area for the suction nozzle. The cover tube has an intake opening for an ambient air lying oppositely to the suction opening. The suction opening has a height of 70 mm, and width of 200 mm and is formed in groove-shaped manner.
