FIELD: power engineering.
SUBSTANCE: invention relates to power engineering. A steam turbine plant comprising a boiler steam superheater, the main steam pipeline connecting a boiler steam superheater with a turbine comprising a bypass pipeline with a reduction-cooling device installed on it, which connects the main steam pipeline with an inlet to a condenser, the steam space of which is separated by a piping system into input and output parts. In the place of connection of the main and bypass pipelines there is a separator of solid particles, at the same time on the bypass pipeline there is a separator of excessive moisture connected to the output part of the condenser by means of a drainage pipeline with a separator and a sludge accumulator.
EFFECT: stated invention eliminates the possibility of excessive moisture and scale ingress into an input part of the condenser steam space, excluding moist-steam erosion of blades of the last steps of the turbine, hydroabrasive erosion of a rod frame and the piping system of the condenser, and also wear of pump equipment and clogging up of drainages and heat exchangers of the STU by sludge, thus increasing its reliability and cost-effectiveness.
