 TURBINE EMERGENCY STOPPED CONDITIONS 

Today we discussed about the emergency stoppage of steam turbine . at which conditions or emergency occurred during steam turbine operation we should immediately stop the turbine. after many research I discussed some point or we can say turbine emergency I found or faced and listening about them I discussed with you at below remembered these point may be changed according to turbine design and capacity :-

When the following occasions happened, the emergency stop shall be made:

(1) When T/G set emerges heavy vibration, or when any shaft vibration exceed 0.05mm:

(2) The turbine rotation speed increased to 3330r/min, and the emergency governor does not act accordingly, after tripping the speed does not decreased;

(3) When water impact emerges;

(4) When the turbine inside emerges metal impact sound, and continued to be expand or shaft seal get sparkles;

(5) When any shaft temperature exceed 105℃;

(6) When oil system gets on fire and can not stamp out quickly;

(7) The oil tank hydro-static level decreased to lowest point;

(8) The main oil pump failure or other fault, the lube-oil pressure decreased to 0.08Mpa and the meter can not control over it which continue to decrease;

(9) Shaft position move exceed rated data, however the protective device does not work;

(10) When rear cylinder membrane security valve works;

(11) Main steam pipe explode;

(12) When the following incident happens, the generator has to tripping from the system:

  1. Generator inside get smoke and fire;
  2. generator vibrate heavily;
  3. equipment accidentally failure and threatened the workers’ life.
