STEAM TURBINE WARMING METHOD

摘要

FIELD: power industry. ^ SUBSTANCE: steam turbine includes partial high pressure turbine and partial intermediate and/or low pressure turbines. Method differs by the fact that to partial high pressure turbine after cold start-up there supplied is steam with relatively high conductivity while partial intermediate turbine and partial low pressure turbine remain closed. As soon as conductivity decreases below certain value, steam is also supplied to partial intermediate pressure turbine and to partial low pressure turbine. ^ EFFECT: reducing the start-up time of units of steam turbine plant in cold state. ^ 2 dwg
