DeNora Anode Ventralizer™
The purpose of an impressed current anode in a groundbed is to electronically conduct current to the coke column. In order for this to work, it is critical that the anode be surrounded by well compacted carbonaceous backfill.
In the installation of LIDA® tubular anodes, a common practice is to “tape” the anodes to the vent pipe — feeding a single assembly down the hole. However, this can result in the anode being too close to the vent pipe to allow the backfill to fill around the entire anode surface during pumping operations. To make matters worse, the non-conductive vent pipe can serve to shield portions of the anode in contact with it, resulting in uneven current discharge of the anode.
To attach the LIDA® tubular anodes to the vent pipe, yet allow sufficient spacing between the node and vent pipe, engineers at De Nora have developed the
The Ventralizer’s™ dual function is to centralize the anode in the hole, and at the same time, provide 1″ of separation between the anode and the vent pipe.
