Jansons was contracted to replace the acid resistant gunite lining in the Unit #4 Stack at Con Edison’s East River Generating Station.
Limited outage constraints necessitated ’round-the-clock’ work, seven days a week. The roof mounted stack required workers to remove debris from the access opening at the roof elevation and then lower material to grade elevation for disposal. Several project highlights included:
Tear-out of approximately 4,000 CF of existing gunite lining and reinforcing steel and mesh
Sandblasting of all exposed interior steel surfaces to a SSPC-6, commercial blast finish
The installation of a 2½” thick gunite lining; including a over 20,000 refractory anchors and 425,000 lbs. of calcium aluminate cement
Platform repairs, grating replacement, testport installation and other miscellaneous repairs
