Abstract: A device for measuring a shape of a wall portion of a coke oven is provided. The device includes a box having a main part defining at least one opening and a closing system movable with respect to the main part between an open position and a closed position, an internal protective screen located within the box and defining at least one scanning window, the scanning window being narrower than the opening along a transverse direction (T) of the box and at least one 3D laser scanner located in the box for scanning the wall portion through the scanning window and through the opening when the closing system is in the open position.

Abstract: The present invention provides a coking plant. The coking plant includes a series of coke ovens, each oven including a coking chamber provided with side unloading doors. The chamber communicates with a riser provided with a coking-gas discharge pipe. The discharge pipes of each oven lead into a collecting cylinder, which is in turn connected to a coking gas treatment circuit. At least one discharge pipe of one of the ovens further includes a device for spraying pressurized liquid onto the wall of the discharge pipe. The liquid flows counter-current with respect to the direction of the flow of the gases exiting the chamber. The present invention also provides a method for controlling such a plant.

Abstract: An endoscopic probe includes an inspection head attached to the end of a longitudinally flexible supporting line which connects it to an operating unit provided with means for moistening the line. The supporting line (2) is rigid under axial torsion, whilst the inspection head (1) is movable in axial rotation and is formed by a demountable assemblage of two parts: a permanent part (11), attached to the end of the supporting line by means of a rotary joint (10) and housing a miniaturized photography device (26), and an interchangeable part (12), fastened rigidly to said permanent part in the extension of the latter with the aid of a demountable joint (44) and comprising a parietal (lateral or axial) orifice provided with a wide angle ocular lens (23) followed by an optical line (25) for conveying the light energy picked up by said lens toward the photography device (26).
