6 FAQs about [Steam turbine generator wind chamber air duct]

Does a combined-cycle power plant have a duct burner?

Most combined-cycle power plants in the United States have duct burners that help them make additional use of combustion turbine exhaust gases.

How does a steam turbine affect the efficiency of a power plant?

However, the dominant contributor to the overall power plant efficiency is the steam turbine itself. The thermodynamic and aerody-namic performance of the steam turbine is pri-marily determined by steam path components, including the valves, inlet, nozzles, buckets, steam leakage control devices and the exhaust.
