THERMAL POWER STATION Russian patent published in 2006 - IPC F01K17/02 

FIELD: heat power engineering.

SUBSTANCE: proposed thermal power station employs type T extraction turbine with seven steam extractions included into regeneration system. Three regenerative high-pressure heaters are connected to first three steam extractions, and four low-pressure regenerative heaters are connected to last four steam extractions. Station contains condenser, upper and lower system heaters connected by heating medium line to sixth and seventh steam extractions, respectively, plant for heating blast air with steam-water heater of system water for air heaters of steam generator connected by heating medium line to steam pipe of fifth steam extraction of type T turbine with heating steam extractions.

EFFECT: improved economy and reliability of thermal power station owing to use of stable low-grade heat source for heating medium in steam-water heater of system water for air heaters of steam generator.
