Abstract (en)
[origin: WO8201057A1] In a heat consumer (2), of which the supply conduit (12) is under a predetermined pressure and of which the return (13) is at a lower pressure, the steam, drawn off from the primary steam circuit in relation to the heat used by the consumer, is cooled down until condensation by drawing off heat by means of a secondary fluid and by maintaining a certain overpressure with respect to the pressure prevailing in the supply conduit (12). This overpressure is reduced to the pressure of the supply conduit (12) by means of a jet pump which allows a drive force to be obtained for the supply conduit (12) and the addition to the supply conduit heated secondary fluid obtained by the cooling of steam. In order to avoid installing an overpressure pump upstream of the jet pump while eliminating superfluous valves and connections, the condensate is accumulated to set the heat consumer temperature and the accumulation of condensate is exclusively set by adjusting the ejection nozzle (10).
