ОСТАНОВОЧНЫЕ РЕЖИМЫ ПАРОВЫХ ТУРБИН С РАСХОЛАЖИВАНИЕМ В БЛОКЕ С КОТЛОМ

Abstract

Considerable duration of natural cooling of steam turbines extends the time of their idling for repair, reduces the installed capacity utilization factor, makes necessary a larger capacity margin in energy systems. The above factors suggest the necessity of introducing various technologies for accelerated withdrawal of steam turbines for scheduled maintenance and emergency repair. Results are stated of a study on shutdown conditions of an off-unit steam turbine with cooldown as a single unit comprising a boiler.
