METHOD FOR OPERATION OF THERMAL POWER STATION Russian patent published in 2007 - IPC F01K17/02 

FIELD: heat power engineering, applicable at thermal power station.

SUBSTANCE: the thermal power station has an extraction turbine, type T, steam is abstracted from its first three bleed-offs to the high-pressure regenerative heaters, and from the last four ones - to the low-pressure regenerative heaters, in which the turbine condensate past the turbine condenser and the feed water are successively heated, and steam from the controlled heating seventh and sixth extractions of the turbine, type T, is abstracted for heating of network water in the lower and upper network heaters respectively, the network water past the network pumps of the second stage is heated in the peak network heater, in which the steam of the third extraction of the turbine, type T, server as the heating medium.

EFFECT: enhanced economical efficiency and reliability of the thermal power station due to provision of a high-efficiency heating of network water in the peak network heater and possibility of rejection of the less economically efficient peak hot-water boilers by using a stable heat source independent of the process steam extraction.
