563-10 - Turbine Efficiency
Learning objectives
- Explain the two methods of calculating turbine efficiency
- Describe how each of the following affects turbine efficiency: chemical deposits and internal erosion, internal and external seal leakage, variations in steam temperatures and pressure, back pressure, attemperation spray flow, and extraction steam flow
- Explain how control valves can be the source of a loss that is typically attributed to the turbine
Course overview
The turbine is one of the most important components in a power plant unit. A reduction in turbine efficiency or integrity can directly affect the unit's production costs, capacity, or safety. Understanding which conditions can increase or decrease turbine efficiency or reliability is vital to keeping the turbine efficient, reliable, and safe.
The Turbine Efficiency training course describes how parameters, components, and problems can affect efficiency. It explains how to calculate turbine efficiency. This online course discusses:
- Turbine efficiency analysis
- Chemical deposits erosion
- Seal leakage
- Steam attributes
- Attemperation
- Steam flow
Turbine Efficiency is part of the Efficiency, Reliability, and Environmentally Sensitive Operations training series.
