Abstract

La présente invention concerne un système d'alimentation en combustible destiné à vaporiser un combustible mixte apporté à un système de production d'énergie. Le système d'alimentation en combustible comprend : un condenseur permettant de condenser une vapeur acheminée à partir d'une turbine du système de production d'énergie; un réservoir de stockage dans lequel le combustible mixte est liquéfié et stocké; un vaporisateur permettant de vaporiser le combustible mixte acheminé à partir du réservoir de stockage; et une première conduite passant à travers le condenseur et le vaporisateur. De l'eau d'échange de chaleur est acheminée à travers la première conduite, l'eau d'échange de chaleur est chauffée dans le condenseur, le vaporisateur vaporise le combustible mixte à l'aide de l'eau d'échange de chaleur chauffée dans le condenseur, et le combustible mixte vaporisé dans le vaporisateur est apporté au système de production d'énergie.
