Objective:
- Understand the operating constraints of steam turbines.
- Determine the causes of performance losses.
- Identify operating anomalies and maintenance consequences.
Target group:
- This course is aimed at operators, foremen, technicians or engineers in operations, maintenance or process departments.
- Prerequisites: Introduction to rotating machines or equivalent experience.
- 8 to 10 people maximum per session.
Contents :
09:00 - 10:30
OPERATION
- Performance: steam characteristics, steam flow, power, efficiency.
- Influence of parameters: steam inlet temperature and pressure, exhaust pressure, rotation speed.
- Operating limits: steam temperature, exhaust pressure.
o Material creep at intake
o Exhaust condensation
o Maximum continuous speed and overspeed
10:30 - 10:45
Break
10:45 - 12:15
OPERATION
- Steam turbine start-up
o Operating constraints, casing and rotor reheating, rotor turning,
o Checking safety systems and alarms
- Operating point and operating limits:
o Regulation: steam flow technology and control
o Operating range, critical speeds, overspeed
o Lubrication: oil circuit
- Protection and safety
o Steam system: inlet and outlet
o Overspeed protection devices: mechanical, electronic
o Radial vibration and axial displacement: principle, safety logic, acceptable limits
o Lubrication circuit
12:15 - 13:15
Lunch
13:15 - 15:15
MALFUNCTION ANALYSIS
- Causes of efficiency losses :
o Steam quality: low enthalpy, soluble and insoluble deposits
o Abnormal pressure drops, clogged suction filter
o Condensation on last stages
- Behavioral anomalies :
o Abnormal rotor vibration
o Abnormal heating of bearings
o Abnormal axial displacement of rotor
15:15 - 15:45
Break
15:45 - 17:00
MAINTENANCE ELEMENTS
- Rotor inspection: non-destructive, dimensional and geometric checks
- Dynamic rotor balancing
- Periodic validation of safety devices
Implementation / working method :
Interactive, one-day, face-to-face course. Powerpoint support will be shared at the start of the course in both paper and digital formats.
A questionnaire will be sent to trainees prior to the course in order to adapt the course content to participants' expectations as far as possible.
A course evaluation questionnaire will be distributed to participants at the end of the course.
