Calculation of the Choked Back Pressure for Steam Turbines with Air Cooled Condensers ()
Abstract
The choked back pressure characteristic of the steam
turbine unit with air cooled condenser is very different with the unit with wet
cooling technology, and the understanding of the choked back pressure
performance change with operation load is important to guide the economic
operation of the unit. One simplified Variable Operation Condition Analysis
Method was put forward for calculation of the unit output-turbine back pressure
characteristics. Based on this method, the choked back pressure for each
operation load can be determined. An example was given for a super-critical,
regenerative single-shaft, 2-casing with 2-exhaust steam turbine generation
unit with air cooled condenser. The calculation result was provided and
compared with the result of the unit with wet cooling technology.
