 At the end of this lesson, you will be able to describe the basic thermal cycles of a combined cycle power plant, including topping and bottoming cycles. You will also be able to list advantages and disadvantages of various combined cycle configurations and define common terminology associated with combined cycle operations. • Explain the thermal cycles of combined cycle plant • Describe a combined cycle plant “topping” cycle • Describe a combined cycle plant “bottoming” cycle • List advantages of a combustion turbinewater/steam combined cycle system • Compare combined cycle plant efficiencies with the efficiencies of simple cycle plants • Describe the way that simple cycle efficiencies can be increased • Define cogeneration and IGCC • Describe the effects of combustion air cooling and supplemental HRSG firing • Explain the difference between a single shaft and multishift combined cycle configuration • Describe the use of single pressure and multi-pressure steam cycle designs
