Combined Cycle Steam and Feedwater Operating Principles
Learning objectives
- Describe the system flow path of a basic single-pressure cycle
- Describe the function of the following components of a HRSG:
- Economizer
- Evaporator
- Superheater
- Explain the concept of a pinch point
- Describe the system flow path of a dual-pressure (HP and LP) cycle
- Describe the system flow path of a triple-pressure (HP, IP, and LP) cycle
- Explain the purpose of a pegging steam line
- Describe the system flow path of a triple-pressure cycle with reheat
- Explain the operation of a HRSG feedwater pump
- Describe the function of a steam attemperator
Course overview
When you complete this lesson, you will be able to describe the feedwater and steam flowpaths in a typical combined cycle power plant. You will also be able to explain the HRSG design principles governing plant operation.
