It travels along the coke-oven battery on the machine side and operates opening of the door of the coking chamber, its cleaning and its subsequent closing.
It further discharges the coke from the coking chamber, cleans the door and the door frame, levels the coal in the chamber and carries out other activities associated with the operation of the coke-oven battery and coking chamber.
The machine usually is of “single-spot positioning” design being able to carry out all the operations associated with operation of the coking chamber from one machine position.
Coke guiding car
It travels along the coke-oven battery on the coke side. Its main task is to transfer the hot coke from the coking chamber to the quenching car. This activity is ensured by a movement of pushing rod from the pushing machine and guiding cage on the coke guiding car moved to the lining of the coking chamber which bridges over the distance between the chamber and the quenching car. The devices of the guiding car open the coking chamber door, clean the door and the door frame and after pushing the coke out and return of the guiding cage to the initial position they close the coking chamber. Apart from other auxiliary operations the activity of the coke guiding car is also focused on the removal of hot air mass with the coke dust originating during coke discharge and fall into the quenching car over the hood, pipeline and transfer system to the dedusting station where the air mass is cleaned.
Location of rails of the car and hence its dimensions and shape respects the technical and environmental protection requirements, space possibilities, customer requirements etc. The coke guiding car usually works with single-spot positioning on the axis of the operated coking chamber.
It travels on the rails situated on the roof of the coke-oven battery, transfers coal from the coal tower, removes the lids of the charging openings, fills the coking chamber and replaces the lids of the charging openings. Other auxiliary operations and activities are carried out by the charging car within the technological cycle - operating (opening, closing) and cleaning the ascension pipes and hydro-injection valves.
According to the way of removal of the raw gas there are the coke-oven batteries with two collecting mains and two rows of ascension pipes or with one collecting main and one row of ascension pipes or with one collecting main and one row of ascension pipes and one row of mini-ascension pipes for transferring charging gases to other chamber already charged earlier. This transfer is carried out by the transferring pipe of charging gases which controls the lids of mini-ascension pipes and provides for transfer of part of the charging gases from the chamber being charged. Charging cars are of single-spot positioning design.
