2. OXYGEN TREATMENT FOR SUPER CRITICAL POWER PLANTS
Supercritical boilers do not have a steam drum. Therefore, extremely high levels of
purity is required for feed water
Poor feed water can result into carry over of impurities which will result in turbine
blade deposits
Oxygen Treatment improves the quality of water by reducing the flow assisted
corrosion.
OXYGENATED TREATMENT
Oxygen treatment minimizes flow assisted corrosion by the production of more stable
iron oxide Hematite layers.
Oxygen gas is dosed at deaerator and Condensate polishing unit outlet through gas
cylinders in a controlled manner.
ADVANTAGES OF OXYGEN TREATMENT
Virtually no iron transport
Virtually no flow assisted corrosion.
Reduced Condensate Polisher regeneration.
Broad pH application range
