Steam turbines

in combined cycle power plants. Siemens has a wide portfolio of cost competitive, high performance, operationally flexible and easily constructable steam turbines for combined cyclepower plants.
Introduction

Efficiency levels of more than 60 percent

In combined cycle power plants (CCPP) a gas turbine generator generates electricity while the waste heat from the gas turbine is used to produce steam to generate additional electricity via a steam turbine. Siemens has a wide portfolio of cost competitive, high performance, operationally flexible and easily constructable steam turbines to meet the diverse needs of customers. The exhaust heat of the gas turbine is utilized to generate steam by passing it through a heat recovery steam generator (HRSG), so it can be used to drive the steam turbine. This combination of two power generation cycles enhances the efficiency of the plant. Combined cycle power plants equipped with the latest Siemens technology achieve unprecedented efficiency levels of more than 60 percent. The high fuel utilization factor of the plant contributes to low lifecycle costs.

Installation of the steam turbine package

After the steam turbine leaves the manufacturing site a challenging journey starts to the customer’s site. However, the most interesting question is:  What happens at the construction site after the turbine package has been delivered? What happens in a certain time frame? What are the single steps of installation? Learn more in our video.
