Abstract: An apparatus for controlling drive or operation of a quenching car and/or a bucket car for a coke oven and a method therefor, capable of effectively accomplishing the automatic control of the operation of the quenching car/bucket car. A quenching car/bucket car is adapted to travel on a track due to traction by a wire rope through a winch structure, to thereby reduce the load of the quenching car/bucket car applied to the track surface to prevent positional variations on the track surface. This results in the relative positional relationship of the track surface to a quenching tower, a coke wharf/CDQ and the like being ensured.

Abstract: A deaerator for particulates capable of increasing the bulk density of the particles to reduce the volume of the particulates. In the deaerator, a perforated cylindrical section (1a) of a cylindrical body (1) includes a filter (13) formed of a sintered material. A screw conveyor (4) arranged in the cylindrical body has a screw pitch (4a, 4b) which is small and which gradually reduces the region on the downstream side of the perforated cylindrical section. The filter may be formed by sintering a fine metal fibre, a metal powder or a ceramic powder.
