Heating system for a thermal electric power station water circuit

摘要

A heating system for a thermal electric power station water circuit includes an extraction system for extracting water from a condenser and a first set of heaters including a first water inlet fed with a first fraction of a flow coming from the extraction system, and a input for heating the extracted water. A second set of heaters includes a heater arranged in series with the extracted-water inlet of the first set, and a steam input for heating the extracted water. A condensate cooler includes a first water inlet fed by a condensate outlet of the second set of heaters, a second water inlet fed with a complementary fraction of the extracted-water flow, a first outlet for cooled condensate to be reinjected into the condenser, and a second outlet for heated water so that water leaving the first set of heaters is mixable with water from the second outlet.

主权项

1. A heating system for a thermal electric power station water circuit, comprising:
an extraction system for extracting water from a condenser; a first set of heaters comprising:
at least one heater,a first water inlet providing an extracted-water-for-heating inlet fed with a first fraction of a flow of extracted water coming from the extraction system, andat least one steam input for heating the extracted water; a second set of heaters comprising:
at least one heater arranged in series with respect to the extracted-water inlet of the first set of heaters, andat least one steam input for heating the extracted water; a condensate cooler comprising:
a first water inlet providing a condensate inlet fed by a condensate outlet of the second set of heaters,a second water inlet fed with a complementary fraction of the extracted-water flow coming from the extraction system, said second water inlet bypassing the first set of heaters,a first outlet for cooled condensate that is configured to be reinjected into the condenser, and,a second outlet for heated water so that a flow of water leaving the first set of heaters is mixable with a flow of water derived from the second outlet of the condensate cooler; and a regulator ‘R’ positioned upstream of the second water inlet of the condensate cooler for regulating the extracted water flow coming from the extraction system so as to allow adjustment of the complementary fraction of the extracted water flow fed to the condensate cooler.
