Title (EN) COMPRESSED-AIR ENERGY-STORAGE SYSTEM
(FR) SYSTÈME DE STOCKAGE D'ÉNERGIE À AIR COMPRIMÉ
Abstract:
(EN) A compressed-air energy- storage system is disclosed, comprising: a variable- nozzle expander (115, 115 A) configured to receive an airflow at a first pressure and partially expand said airflow at a second pressure, said second pressure being lower than said first pressure, expansion of said airflow in said variable-nozzle expander producing useful mechanical power; a heat generator component (125) configured to receive a fuel and a partially expanded airflow from the variable-nozzle expander (115, 115 A); a turbine (131) configured to receive combustion gas from the heat generator component (125) and expand the combustion gas producing useful mechanical power.
(FR) La présente invention se rapporte à un système de stockage d'énergie à air comprimé qui comprend : un dispositif de dilatation à buse variable (115, 115A) configuré pour recevoir un flux d'air à une première pression et pour dilater partiellement ledit flux d'air à une seconde pression, ladite seconde pression étant inférieure à ladite première pression, la dilatation dudit flux d'air dans ledit dispositif de dilatation à buse variable produisant une puissance mécanique utile ; un composant générateur de chaleur (125) configuré pour recevoir un combustible et un flux d'air partiellement dilaté provenant du dispositif de dilatation à buse variable (115, 115A) ; une turbine (131) configurée pour recevoir un gaz de combustion provenant du composant générateur de chaleur (125) et pour dilater le gaz de combustion afin de produire une puissance mécanique utile.
