Title
(EN) EXHAUST GAS ENERGY RECOVERY SYSTEM
(FR) SYSTÈME DE RÉCUPÉRATION DE L'ÉNERGIE D'UN GAZ D'ÉCHAPPEMENT
Abstract
(EN) An exhaust gas energy recovery system includes a power plant and a volumetric fluid expander. The power plant has an exhaust gas outlet for conveying an exhaust gas stream at a first pressure. The volumetric fluid expander includes a housing and an output shaft. The housing has an inlet and an outlet, and the housing inlet is in fluid communication with the exhaust gas outlet. The volumetric fluid expander generates useful work at the output shaft by expanding the exhaust gas stream to a second pressure lower than the first pressure generally without reducing the volume of the exhaust stream as the exhaust stream moves from the housing inlet to the outlet.
(FR) La présente invention concerne un système de récupération de l'énergie d'un gaz d'échappement qui comprend une centrale électrique et un détendeur de fluide volumétrique. La centrale électrique possède un orifice d'évacuation de gaz d'échappement permettant de transporter un flux de gaz d'échappement à une première pression. Le détendeur de fluide volumétrique comprend un boîtier et un arbre de sortie. Le boîtier possède un orifice d'admission et un orifice d'évacuation, et l'orifice d'admission du boîtier est en communication fluidique avec l'orifice d'évacuation du gaz d'échappement. Le détendeur de fluide volumétrique génère un travail utile au niveau de l'arbre de sortie par la détente du flux de gaz d'échappement à une seconde pression inférieure à la première pression généralement sans réduire le volume du flux d'échappement au fur et à mesure que le flux d'échappement se déplace de l'orifice d'admission du boîtier vers l'orifice d'évacuation.
