When Is Steam Jet Air Ejector Maintenance Required?
- Water issuing from after condenser vent
- Turbine fire in the plants operating history
- Last internal inspection of air ejector >7 years
- Numerous leaks identified on air ejector during in-leakage inspection
Dimensionally Incorrect Steam Nozzles Will Result in One or All the Following:
- Poor vacuum with minimal sources of air leakage identified.
- No shock wave or cold region identifiable on the ejector diffusers
- Surging or stalling sounds coming from the ejector stages.
- Station required to operate both sets of ejectors to maintain vacuum.
What is Included in Steam Jet Air Ejector Maintenance from AES?
- Air ejectors are disassembled and inspected to identify internal degradation.
- Repairs are made and internals cleaned and restored to manufacture’s specification.
- Condensers are inspected on both shell and tube side to determine required maintenance.
- Drains are disassembled and inspected along with rebuild/replacement of drain traps.
- A detailed report w/ pictures documenting all maintenance.
Typical Findings:
- Loose steam nozzle resulting in erosion of steam chest
- Plugged air ejector drains
- Plugged air ejector nozzles
- Worn air ejector nozzles
- Incorrect/improper gasket installation
Expected Performance Results Post Maintenance:
- Air removal system is capable of operating with single stage of 1st and 2nd stage ejectors
- Condensate will be within the capacity of the condenser drain system eliminating moisture in the air ejector vent
- Steam will no longer emit from the air ejector vent
- Hogger operation will be limited to startup operation only
- Vacuum will be restored to design levels that will support generation schedule
