Updated Jan 21, 2021

 Upon completing this lesson, you will be able to describe the basic components of a steam turbine and explain its purpose in relation to a combined cycle power plant. In addition, you will be able to identify common turbine auxiliaries and describe basic steam turbine operations. • Describe the energy conversions that take place between the HRSG and steam turbine • Recall the steam flow path through a high, intermediate, and low-pressure turbine • Identify the purpose of the following steam turbine valves: – Main steam stop valves – Turbine governor and control valves – Reheat and intercept valves • Identify the difference between full arc admission and partial arc admission
