Abstract
A gas-transfer tube assembly is used to extract charging gases through an orifice in the roof of one coke oven chamber and discharge the gases into an adjacent second coke oven chamber through an orifice in the roof thereof. Each orifice has a riser with an annular water seal normally closed by a removable cover. The gas-transfer tube assembly includes downwardly-extending tubular end portions with elbow parts that are selectively connected together by a straight mid-section used to change the spacing between the downwardly-extending end portions. The gas-transfer tube assembly is supported for vertical movement on a car that runs along a monorail supported by buckstays. The car is stabilized by rollers at the top of the car to engage a rail.
