GB/T 754-2007

This standard specifies the terminology and definitions of steam turbines for power generation, the series of new steam parameters, and the allowable fluctuation range of steam inlet parameters during operation, etc. This standard applies to fixed-type steam turbines (condensing type) or combined heat and power (back-pressure type, extraction back-pressure type, extraction condensing type) used for power generation with a rated power range of 0.75MW to 1000MW or more, and a new steam pressure range of 1.28MPa to 31MPa or higher. This standard does not apply to nuclear power steam turbines and steam-gas combined cycle steam turbines.
