Combined cycle power plants need a constant supply of water to produce steam in a heat recovery steam generator, or HRSG. The feedwater pumps supply water to the HSRG where it produces steam sufficient for driving a turbine generator.

A typical HRSG consists of three pressure modules, each of which can produce a different steam pressure. These steam pressures correspond to the low pressure, intermediate pressure, and high pressure stage of the steam turbine.

The Combined Cycle Steam and Feedwater Operating Principles training course describes the feedwater and steam flow paths in a typical combined cycle plant. It also explains the HSRG design principles that govern plant operations. This online training course covers:

• HRSG steam production
• Common HRSG designs
• HRSG feedwater systems

This course is part of the Combined Cycle Power Plant Operations series.
