Refining the calculation procedure for estimating the influence of flashing steam in steam turbine heaters on the increase of rotor rotation frequency during rejection of electric load

Abstract

A refined procedure for estimating the effect the flashing of condensate in a steam turbine's regen-erative and delivery-water heaters on the increase of rotor rotation frequency during rejection of electric load is presented. The results of calculations carried out according to the proposed procedure as applied to the delivery-water and regenerative heaters of a T-110/120-12.8 turbine are given. © Pleiades Publishing, Inc., 2012.
