Bases of газодинамики are expounded at the flow of environment through the channels of turbine grates, structural features of condensation and introduction of a heating system turbines of ТЭС and АЭС, and also their ancillaries. Bases of exploitation of turbine equipment in obedience to ПТЭ, maintenance of working turbine and ancillaries, starting and stop of steam-turbine, are considered. Requirements over are brought to organization repair maintenances of turbines and ancillaries. The features of exploitation and repair of turbines of АЭС are reflected.For the students of establishments of higher education on specialities the "Паротурбинные options of the nuclear power electric stations", "Planning and exploitation of the nuclear power electric stations", "Thermal electric stations", "Automation and management by теплоэнергетическими processes".It can be useful studying power colleges.
