Opis:
The paper deals with new construction of low pressure cylinder (LPC) for condensing steam turbines. The flow path of these cylinders is formed on the base of new two-tier stages. As opposed to well known Baumann’s stages newer two-tier stages is a combination of two independent stages with own blades set. Such construction allows to decrease the number of LPC in the existing turbines or to ensure their operation with very high vacuum in the condenser or increases in 1.5 times power capacity of new turbines without increasing of the last stage blade length and LPC number.

Opis:
This paper presents effective ways to increase the carrying and reliability of thrust bearings. Technical solutions implemented by TRIZ Ltd have been considered. In comparative characteristics of the bearing took into account such factors as: capacity, peripheral speed at the average radius, speed at the periphery, specific pressure, specific lubricant consumption. Comprehensive analysis of the working conditions of bearing was aimed to protect against electroerosion.

Opis:
The results of the gas-dynamic calculation of the low-pressure cylinder flow part of the K-220-44 type steam turbine intended for operation at nuclear power plants are presented. The ways of the flow part improvement were determined. Some of those ways include the use of innovative approaches that were not previously used in steam turbines. The design of the new flow part was carried out on the basis of a comprehensive methodology implemented in the IPMFlow software package. The methodology includes gas-dynamic calculations of various levels of complexity, as well as methods for analytical construction of the spatial shape of the blade tracts based on a limited number of parameterized values. The real thermodynamic properties of water and steam were taken into account in 3D calculations of turbulent flows. At the final step, end-to-end 3D calculations of the lowpressure cylinder that consists of 5 stages were performed. The technology of parallel computing was applied in those calculations. It is shown that due to the application of innovative solutions, a significant increase in efficiency can be achieved in the developed low-pressure cylinder.
