Abstract
An apparatus for the provision of a block flange of a manhole aperture or the like, in particular for fluidized bed reactors for the oxychlorination of ethylene, oxygen and HCl, having a wall flange fixed in the reactor wall, is intended to provide a solution whereby all other auxiliary measures can be dispensed with and the expense associated therewith can be eliminated without the functionality of the system suffering as a result and without undesirable deposits being formed in these areas. This is achieved in that the flange surface () pointing inward and downward in the direction of gravity is of beveled design, at least in some areas.
