Title
(EN) TURBINE WASHING FOR CHARGED INTERNAL COMBUSTION ENGINES
(FR) NETTOYAGE DE TURBINE POUR MOTEURS À COMBUSTION INTERNE SURALIMENTÉS
Abstract
(EN) Restricting exhaust gas treatment devices from contacting a washing medium supplied by a washing system may reduce affecting the exhaust gas treatment devices. A washing system (50) may comprise a washing device (52) configured to supply a washing medium to a turbine (TH ) during an ON mode of the washing system (50) and a fluid flow control system (38). The fluid flow control system (38) may be configured, during an OFF mode of the washing system (50), to direct exhaust gas through the at least one exhaust gas treatment device (41), and during the ON mode of the washing system (50), to restrict a mixture of exhaust gas and washing medium exiting the turbine ( TH ) from being directed through the at least one exhaust gas treatment device (41).
(FR) Le fait de limiter le contact entre des dispositifs de traitement des gaz d'échappement et un agent de lavage fourni par un système de lavage permet de réduire la perturbation des dispositifs de traitement des gaz d'échappement. Un système de lavage (50) peut comprendre un dispositif de lavage (52) conçu pour fournir un agent de lavage à une turbine (TH) pendant un mode MARCHE (ON) du système de lavage (50) et un système de commande d'écoulement de fluide (38). Le système de commande d'écoulement de fluide (38) peut être conçu, pendant un mode ARRET (OFF) du système de lavage (50), pour guider les gaz d'échappement à travers le(s) dispositif(s) de traitement des gaz d'échappement (41) et, pendant le mode MARCHE (ON) du système de lavage (50), pour limiter le guidage d'un mélange de gaz d'échappement et d'agent de lavage sortant de la turbine (TH) à travers le(s) dispositif(s) de traitement des gaz d'échappement (41).
