Abstract (en)
[origin: EP1191192A1] The method of heat drawing of steam feed lines connected to steam turbine stages entails directing the heat drawn steam after its passage through the first feed line (1) through a connecting line (5) opened during heat drawing to a second feed line (2). The steam is then directed through the section of the second feed line for heat drawing against the flow of steam defined for running of the turbine, and finally diverted through the bypass line (7) of the second steam feed line. An Independent claim is included for a system for draining and heat drawing of steam feed lines connected to steam turbine stages.
