Numerical Study on Condensing Flow in Low Pressure Cylinder of a 300MW Steam Turbine
Volume 7: Turbomachinery, Parts A, B, and C, 2010The flow in low pressure (LP) cylinder of steam turbine is the well-known non-equilibrium condensing flow. If the LP cylinder is designed based on the equilibrium condensation theory, the flow parameters in the actual non-equilibrium condensing flow are different from the design condition, which will bring to additional ‘off-design’ losses besides the ...

Shaft seals with an easily removable cylinder holder for low-pressure steam turbines
Thermal Engineering, 2015The article is devoted to the problems that occur at the operation of LPC shaft seals (SS) of turbines, particularly, their bearings. The problems arising from the deterioration of oil-protecting rings of SS and bearings and also the consequences in which they can result are considered. The existing SS housing construction types are considered.

Prospects of using two-tier low-pressure cylinders in steam-turbine power units
Thermal Engineering, 2009Possible ways for increasing the throughput capacity of the low-pressure cylinders of the condensing steam turbines are discussed. It is shown that the use of two-tier low-pressure cylinders allows the flowrate of steam through them to be increased by 65–70% without the need of increasing the length of last-stage blades.
