FIELD: power engineering.
SUBSTANCE: invention relates to power generating plants on base of steam screw machine. Proposed plant contains steam screw machine whose output shaft is coupled with loading device, and two-position steam selector connected with automatic control and protection system by means of operating mechanism and provided with input and standard output communicating with steam input in steam screw machine. Steam selector is provided additionally with emergency output and servo cylinder with piston installed for travel and fitted on rod on ends of which standard output valve and emergency output valve are secured. Diameter of piston is greater than diameter of emergency output valve. Operating mechanism of steam selector is furnished with bypass branch pipe connected with its servo cylinder, input branch pipe connected with its input and output branch pipe communicating with atmosphere.
EFFECT: provision of complete protection of power generating plant in emergency.
