Изобретение относится к области теплоэнергетики, в частности к паровым турбинам, и может быть использовано для ускоренного их расхолаживания при выводе в ремонт, а также при консервации оборудования в случае длительных остановок. Цель изобретения: сокращение времени расхолаживания и уменьшение коррозии основного оборудования в периоды краткосрочных и длительных остановок турбин. Способ заключается в подаче сжатого воздуха с разнотемпературными потоками из вихревой трубы в цилиндр высокого давления, на концевые уплотнения ротора и систему обогрева фланцевых соединений цилиндра турбины. Новым в способе является то, что сжатый воздух перед подачей в вихревую трубу охлаждают холодным потоком воздуха, подаваемым на охлаждение фланцевых соединений, из которых отработанный воздух направляют в эжектор.The invention relates to the field of power engineering, in particular to steam turbines, and can be used to accelerate their cooling down when taking them out for repair, as well as during equipment conservation in case of long shutdowns. The purpose of the invention: reducing the time of cooling and reducing corrosion of the main equipment during periods of short-term and long-term shutdowns of turbines. The method consists in supplying compressed air with different temperature flows from a vortex tube to a high pressure cylinder, to the end seals of the rotor and the heating system of the flange joints of the turbine cylinder. New in the method is that the compressed air before being fed into the vortex tube is cooled by a cold stream of air supplied to cool the flange joints, from which the exhaust air is sent to the ejector.
