2 x 770 MW units in New Mexico will be run with FGD Wet Stacks. This video shows how Hamon Custodis installs PennguardTM linings on the brick flues to stop condensate from permeating through the brick.

2 x 770 MW coal fired Power Station
Four Corners Power Station is owned by Arizona Public Service. The two 770 MW units are equipped with wet limestone FGD systems. The scrubbed flue gas exit temperature will be lowered to 48ºC. With such low temperature FGD operation acidic flue gases will penetrate through brick liners. The owner found that the PennguardTM Block Lining System is an effective system to seal the brick from these acidic condensates.
A positive barrier
This is the outside surface of the Four Corners Unit 4 and 5 brick liners where you can see the acid coming through the brick joints. A lightweight, impermeable PennguardTM lining will completely stop the permeation of acidic condensate through the brick.
Flexible and adaptable
By their nature, most brick flues have irregularities such as bulges, offsets between bricks and narrow cracks. Thanks to the limited size of the PennguardTM Blocks and the flexibility of its adhesive, a PennguardTM lining will readily adapt to most of these irregularities.
No anchors, no supports
A PennguardTM lining is lightweight and fully bonded to the brick substrate by its adhesive. It does not require any anchors or supports that could lead condensate into the lining and create weak spots as a result of corrosion.
