Title (EN) SYSTEM FOR RECOVERING WASTE HEAT
(FR) SYSTÈME DE RÉCUPÉRATION DE CHALEUR RÉSIDUELLE
Abstract:
(EN) A waste heat recovery system (10) includes a heat generation system (18) including at least two separate heat sources having different temperatures. A rankine cycle system (12) is coupled to the at least two separate heat sources (16, 44) and configured to circulate a working fluid. The rankine cycle system is coupled to at least one heat source and another heat source among the at least two separate heat sources. The rankine cycle system is configured to remove heat from the at least one heat source to partially vaporize or preheat the working fluid; and remove heat from the other heat source to vaporize or superheat the working fluid.
(FR) La présente invention concerne un système de récupération de chaleur résiduelle comportant un système de génération de chaleur comprenant au moins deux sources de chaleur distinctes ayant des températures différentes. Un système à cycle à de Rankine est couplé à au moins une source de chaleur et une autre source de chaleur parmi lesdites deux sources de chaleur distinctes. Le système à cycle de Rankine est configuré pour éliminer la chaleur depuis ladite une source de chaleur pour évaporer ou préchauffer partiellement le fluide de travail; et pour éliminer la chaleur depuis l'autre source de chaleur pour évaporer ou surchauffer le fluide de travail.
