PROTECT POWER PLANTS AGAINST CORROSION WITH DEHUMIDIFICATION

Ensuring Dry Environments for Power Stations

Hydroelectric power stations stand as bastions of energy production, yet they face a relentless threat: moisture. The very substance they harness for power poses a risk to their machinery and control systems through insidious condensation.

Vital Areas Requiring Drying During Shutdown

Generator Maintenance

The heart of power generation, the generator, demands meticulous care. Ensuring the windings remain dry is paramount to staving off corrosion and facilitating swift startups. Dry air proves invaluable, complementing generator heaters for optimal functionality.

Preserving the Condenser

After flushing, the condenser enters a critical phase. Keeping it dry is imperative, facilitating the recoating process for water boxes and tube plates. This proactive measure safeguards against potential damage.

Safeguarding the Reheater

Vulnerable to corrosion, reheater tubes require special attention. Thinner than superheater tubes, they are more prone to intergranular attacks. Introducing dry air minimizes these risks, preserving the integrity of austenitic stainless steel.

Maintenance of Feed and Condensate Pipes

Internally, feed and condensate pipes harbor a hidden menace: corrosion. Oxide buildup can contaminate feed water, compromising system efficiency. By eliminating internal corrosion, power stations ensure operational reliability.

Boiler Protection

Boiler surfaces face a perilous threat: condensation. As temperatures plummet below the dew point, condensate forms, initiating a corrosive cascade. Acidic solutions corrode metal surfaces rapidly, necessitating vigilant protection measures.

Reactor Vessel Care

Within the reactor vessel lies a delicate balance. Purging CO2, combating corrosion, and drying graphite demand precision. Dry air serves as a vital tool, preparing the vessel for maintenance tasks and ensuring operational readiness.

Conclusion

In the realm of power generation, vigilance against moisture reigns supreme. Through strategic dehumidification, power plants fortify themselves against corrosion’s relentless advance, ensuring longevity and operational excellence.
