Effective Solutions for Equipment Preservation
Preserving power generation equipment is essential to maintaining operational efficiency, reducing maintenance costs, and preventing corrosion-related damage. Excess moisture leads to degradation of critical components, increasing repair costs and reducing equipment lifespan.
Protecting Power Generation Equipment from Corrosion
During long idle periods, equipment in thermal and nuclear power plants is highly susceptible to corrosion, requiring effective humidity control to maintain its integrity.
DT Group Dehumidifiers Are Used for Preserving:
- Turbines, Boilers, Steam & Gas Circuits
- Generators & Condensers
- Ash & Slag Removal Systems
- Electric Filters & Feeding Electric Pumps
- Substations, Switchgears & Transformers
- Cabinets, Block Boards & Reserve Containers
Why Is Humidity Control Essential?
Uncontrolled humidity accelerates metal corrosion, leading to costly repairs and reduced efficiency.
- At 60-100% relative humidity, steel corrodes 100-2000 times faster than at 30-40% relative humidity.
- For boiler steels, corrosion increases significantly above 60% humidity, reducing metal thickness by 0.057 mm per year.
Maintaining low humidity levels ensures cost-effective operation and long-term equipment preservation.
Limitations of Traditional Preservation Methods
Common preservation techniques, such as chemical inhibitors, nitrogen purging, steam pressurization, and vacuum drying, have significant drawbacks:
- High Costs: Expensive chemicals, complex handling, and waste disposal.
- Environmental Concerns: Chemical use poses ecological risks.
- Energy-Intensive: Ventilation, heating, and air treatment require substantial power.
- Limited Maintenance Access: Repairs cannot be conducted during preservation.
Due to these limitations, desiccant drying technology is a superior alternative for power plant preservation.
