HEATING SYSTEM FOR WATER CIRCUIT OF THERMAL POWER PLANT Russian patent published in 2015 - IPC F01K13/00 

FIELD: power industry.

SUBSTANCE: invention relates to power industry. A heating system for a water circuit of a thermal power plant, which includes a water sampling system from a condenser, the first set of heat exchangers, which includes at least one heat exchanger, a water inlet that is mentioned as an inlet for water taken for heating, which is fed by the first fraction of a sampled flow of water supplied from the sampling system, and at least one inlet for steam intended for heating of sampled water, and the second set of heat exchangers, which includes one heat exchanger mounted in series relative to the sample water inlet of the first set of heat exchangers, and one inlet for steam intended for heating of the sampled water. Additionally, the heating system includes a condensate cooler. Besides, the invention presents a thermal power plant containing a heating system according to the invention.

EFFECT: invention allows optimising an energy balance and at the same time ensuring maximum safety level for a turbine, minimum service level and a possibility of providing the best chemical quality of feed water.
