The document discusses gas and steam turbine combined cycle power plants. It explains that a gas turbine produces waste heat that is used to generate steam in a heat recovery steam generator, and the steam then powers a steam turbine. The document provides details on the components of combined cycle power plants, including the gas turbine, HRSG, and steam turbine. It also discusses the materials, types, cycles, emissions controls, and economics of combined cycle power plants.
