Оценка эффективности работы ЦНД турбины Т-250/300-23,5 Харьковской ТЭЦ-5

Abstract

It was proposed to carry out an estimation of the steam turbines flow paths efficiency for the low pressure cylinder in general and particularly for the low pressure cylinder of the T-250/300-23,5 steam turbine taking into account inherent operation conditions. Basing on such estimation it is possible to make recommendations for flow path modernization. Efficiency estimation for the each modernized variant should be developed basing on rate of the electrical energy generation. The rate can be determined by using the integrated characteristics of the turbine stages, i.e. mass flow rate, heat drop, performance factor in varying duty that were obtained as experimentally as well in calculations.
