3 Terms and definitions
GB/T 5578-2007 defined and the following terms and definitions apply to this document. For ease of use, the following list is repeated
GB/T 5578-2007 some of the terms and definitions.
3.1
Mixed-pressure turbines
Different pressure steam into the steam turbine work of the same turbine.
Note. Most of the combined cycle turbines are turbocharged turbines, usually with double-pressure combined cycle turbines and multi-pressure combined cycle turbines. Double pressure means more than
The heat boiler will produce two different pressure steam into the same steam turbine work. Three pressure type refers to the waste heat boiler will produce three different pressure steam into the same
First steam turbine work. Multi-press and so on.
[GB/T 5578-2007, Definition 3.1.5]
3.2
NCB Turbine "NCB" turbine
According to the needs of users can be pure condensate (abbreviated as "N"), extraction (abbreviated as "C") or back pressure (abbreviation "B"), etc.
Turbine with operating mode switchover.
