Влияние начальных параметров на характеристики проточных частей турбин, работающих на низкокипящих рабочих телах

Abstract

A comparative analysis of supercritical and subcritical steam turbine cycles with low-boiling actuating medium has been done. The effect of initial steam parameters at the turbine inlet on the metering, geometric and power characteristics of the turbine was demonstrated using different actuating media. Steam turbine cycles of this type using the mix (multicomponent) medium or single-component actuating medium that define the amount of capital expenditures and have an impact on the further operation of heat flow diagram have also been compared. Computation studies of the flow system of turbines using different actuating media were carried out taking into consideration the thermodynamic properties and peculiarities of low-boiling actuating media in question.
