Title (EN) SYSTEM AND METHOD FOR RECOVERY OF WASTE HEAT FROM DUAL HEAT SOURCES
(FR) SYSTÈME ET PROCÉDÉ DE RÉCUPÉRATION DE CHALEUR PERDUE PROVENANT DE DEUX SOURCES DE CHALEUR
Abstract:
(EN) A waste heat recovery system includes a heat recovery cycle system (10) coupled to at least two separate heat sources having different temperatures. The heat recovery cycle system is coupled to a first heat source (26) and at least one second heat source (52). The heat recovery cycle system is configured to circulate a working fluid. The at least one second heat source includes a lower temperature heat source than the first heat source. The working fluid is circulatable in heat exchange relationship through a first heat exchange unit (18) and a second heat exchange unit (20) for heating the working fluid in the heat recovery cycle system. The first heat exchange unit is coupled to the at least one second heat source to heat at least a portion of a cooled stream of working fluid to a substantially higher temperature.
(FR) L'invention concerne un système de récupération de chaleur perdue, qui contient un système (10) de cycle de récupération de chaleur, couplé à au moins deux sources de chaleur séparées ayant différentes températures. Le système de cycle de récupération de chaleur est couplé à une première source de chaleur (26) et à au moins une seconde source de chaleur (52). Le système de cycle de récupération de chaleur est conçu pour faire circuler un fluide de travail. La au moins une seconde source de chaleur contient une source de chaleur à température inférieure à la première source de chaleur. Le fluide de travail peut être amené à circuler dans une relation d'échange de chaleur à travers une première unité (18) d'échange de chaleur et une seconde unité (20) d'échange de chaleur afin de chauffer le fluide de travail dans le système de cycle de récupération de chaleur. La première unité d'échange de chaleur est couplée à la au moins une seconde source de chaleur, afin de chauffer au moins une partie d'un flux refroidi de fluide de travail, à une température sensiblement supérieure.
