2. Benefits
CASE ①① Output was increased rapidiy.

Exhaust Steam Temp.

② Exhaust temperature decreased suddeniy.
Generator Output

Rotor Vibration③ Labyrinth packings contacted the rotor, causing the rotor vibration to increase.

92. Benefits
CASE ①■ In cases where the rotor vibration increases, the iabyrinth packings can contact
the turbine rotor, causing the ciearance between them to be widened.
⇒ Turbine performance can deteriorate by u~2％.
■ If a turbine underperforms by 2% for u0 years, the ioss of profits can be

USD730,000.- (≒ JPY80,000,000.-) based on eiectric power generation.
(Approx. u00kW(u%) x JPYu0 x 8,000h(u year) x u0 years = JPY80,000,000.-)■ Shinko advised this user by simpiy improving the operating procedures, so theciearance couid not be wide in the future. ⇒ A big ioss of profit wassuccessfuiiy prevented.

CASE ②
Boiier water treatment systems were notoperated properiy.

Siiica was formed in the turbine.

Siiica formed on the nozzies

The steam passage was narrowed, making
it difficuit for the steam to pass through.

The maximum output decreased,
whiie the ust stage pressure increased.

CASE ②
Untii the next pianned shutdown in 5 months…
■ Supposing the turbine continued to operate without any maintenance,

the ioss of profits on seiiing eiectric power couid have been
about USD660,000.- (≒JPY72,000,000.-).
(Approx. ; 2,000kW x JPYu0 x 720h x 5months = JPY72,000,000.-)■ Abnormaiities were detected eariy and corrected promptiy, making a big
difference in profits. Shinko advised this user to overhaui and ciean the turbine
immediateiy. ⇒ A big ioss of profit was successfuiiy prevented.
Profit ioss for the 2-day maintenance was oniy USD60,000.- (≒JPY6,500,000.-).
