Course Objective:

• Explain steam turbine thermodynamics and energy conversion.
• Differentiate impulse vs. reaction turbines.
• Describe back pressure, condensing, extraction, and induction turbines.
• Explain lubrication, seal steam, and condensate/vacuum systems.
• Identify major components and their functions (casing, rotor, blades, shaft, bearings, seals, valves).
• Perform safe startup and shutdown procedures.
• Explain efficiency's effect on cost, energy, and profitability.
• Troubleshoot common turbine faults.
• Execute a complete overhaul (disassembly, inspection, reassembly).
• Apply reliability strategies (run-length surveys, turnarounds, preventive vs. predictive maintenance).
• Select and specify turbines based on materials, application, and lifecycle cost.
