METHOD OF OPERATION OF EXTRACTION TURBINE PLANT

摘要

FIELD: heat power engineering. ^ SUBSTANCE: invention can be used at thermoelectric plants. Invention is aimed at increasing power and economy of extraction turbine plant with three-stage heating of system water at cutting off supply of peak-load boiler with turbine extraction steam and after-heating of system water in peak-load hot water boiler. According to invention, diaphragm is removed from holder of intermediate compartment in first pressure stage in direction of steam flow, blades of disk in this stage are removed and roots of blades are fitted-in instead of removed blades. ^ EFFECT: increased power and economy of extraction turbine plant. ^ 1 dwg
