563-13 - Feedwater Heater Operation and Efficiency
Learning objectives
- Describe the normal operations of a feedwater heater
- Identify problems commonly associated with feedwater heaters and describe how they affect unit efficiency and reliability
- Discuss the following methods of evaluating feedwater heater performance: feedwater heater temperature rise, drain cooler approach (DCA), and terminal temperature difference (TTD)
Course overview
Steam is extracted from the turbine at various points after some of its energy has been used to make electrical energy. This steam is used for various purposes. Feedwater heaters use a large portion of extraction steam to heat condensate and feedwater before it returns to the boiler. This practice makes the unit more efficient and reliable.
The Feedwater Heater Operation and Efficiency training course describes operations. It also discusses problems that affect performance. This online training course covers:
- Normal feedwater heater operation
- Methods of evaluating feedwater heater performance
- Common feedwater heater problems
- Effects of poor feedwater heater performance
This course is part of the Efficiency, Reliability, and Environmentally Sensitive Operations training series.
