Abstract

Abstract An evaporating apparatus comprising a high temperature side evaporator and a low temperature side evaporator connected in series in a flowing direction of a heat source, a first and second pipe line for directing fluid being evaporated therethrough, and an ejector having a suction inlet and a discharge outlet of drive steam and an induction port of steam being sucked, wherein the first pipe line is linked through the high temperature side evaporator to the suction inlet of the ejector, and the second pipe line is branched from the first pipe line at the upstream side of the hot temperature side evaporator, and linked through the low temperature side evaporator to the induction port of the ejector.
