Steam Turbine Generator Erection in Gas Fired CC PlantNot at all uncommon, this project features the use of Barnhart’s Modular Lift Tower (MLT) in a Stator Frame configuration. In the course of erecting most combined cycle power plants, the erection of the steam turbine and particularly the steam turbine generator can pose unique challenges. The conventional method of erection is the use of a heavy lift crane to set these major components, but often the crane has already departed from the site following the erection of the Heat Recovery Steam Generator units. In an effort to provide our customers with an economical alternative, we developed the Modular Lift Tower.
In this application, the contractor was only required to leave out one bay of steel during the steam turbine building erection. Using the MLT stator frame with a heavy swivel the unit was easily lifted from the transporter and negotiated through the steel to its pedestal. Because the MLT mobilizes in less than eight truckloads as compared to a heavy lift crane which may require forty or more loads, it offers excellent economics.
The MLT has been used throughout the country to erect every type of steam turbine and generator. The system is also easily arranged in a configuration to allow erection of the rotating equipment from the end of the pedestal as well.
