Abstract
Burner tubes for coke oven heating flues and method and apparatus for inserting and/or removing the same from burner nozzles. The burner tubes themselves can be inserted or removed from burner nozzles permanently installed in the sole of a heating flue and comprise thin-walled alumina elements provided with external fins adapted to engage the top edges of the burner nozzles. The apparatus for inserting and removing the tubes comprises two pivotally-connected rods, the lower of which is adapted to carry either a fixture which can insert a burner tube into a burner nozzle or a fixture which can remove a burner tube. In either case, the fixture is such that it can be engaged with, or disengaged from, a burner tube by manipulation of the uppermost pivotally-connected rod without manual contact with the tube in the heating flue itself.
