Use Of Metal Bellows Noncontacting Seal And Guidelines For Steam Applications.
MetadataShow full item record
Steam turbines are used throughout the process industries and provide a reliable means of driving pumps, compressors; and other rotating equipment. Carbon rings are currently the most common way . of seali g these turbines. Although simple in design, the sealmg capability of these devices is very low. This results in high steam losses, lower efficiency, and decreased equipment reliability. This paper discusses the design and testing of a new noncontacting seal for operation in steam turbines. This seal was desi ned to improve turbine efficiency �and equipment reliability. Details from three field applications are discussed. Guidelines for installation and operation of steam turbine seals are also discussed, based on experience in the laboratory and field applications.
