Retrofit Installation Of A Boiler Feed Pump Hydraulic Coupling.
MetadataShow full item record
The application of main turbine-generator shaft drive for boiler feed pumps is generally accepted as a method to increase unit efficiency. The use of shaft drive eliminates the power requirement of an auxiliary motor or turbine drives. The addition of variable speed to this shaft drive provides economic advantages at lower unit loads. During the installation of any equipment, it is necessary to pay particular attention to all facets of the design. It is especially important when dealing with an operating facility for which many design details are not readily available. A case history of a utility's experience in installing variable speed hydraulic couplings for main boiler feed pump drive service is presented.
