METHOD FOR OPERATION OF DUAL-PURPOSE TURBINE PLANT

摘要

A method for operation of dual-purpose turbine plant includes passing system water through system heater, connection pipeline with slide and part of bypass pipeline, control of temperature of system water in direct main by means of rotary diaphragms of first stages of low pressure section. Control of steam flow rate through system heater of lower stage is carried out at modes of change of temperature of external air. At that control of steam flow rate to system heater of the lower stage is carried out by closing rotary diaphragms of the first stages of low pressure section till obtaining maximal increase of turbine plant power.
