Efficient Power Plant Operation

Efficient Unit Startup Explain how efficiency losses can be minimized during a unit startup. Identify key tasks associated with an efficient boiler startup and an efficient turbine startup. Describe the basic guidelines for an efficient unit shutdown. Reduced Power Operation Explain why unit heat rate is higher during reduced power operation. Explain why deviations in parameter values during reduced power operation cause greater increases in unit heat rate. Handling Changes in Weather Conditions Describe how high humidity rain and snow and changes in air and circulating water temperatures affect efficiency and heat rate. Describe how efficiency losses can be minimized during rain and snow. Describe how efficiency losses can be minimized when air and cooling water temperatures change.
