Abstract

La chaudière comporte au moins un premier échangeur de chaleur (10) dont l'entrée est reliée à une conduite d'alimentation en eau (18) et dont la sortie est reliée, à travers une première vanne de réglage (30) à une turbine à vapeur, soit directement, soit à travers un second échangeur de chaleur (12). Pendant la phase de démarrage la vanne de réglage (30) est fermée et aussi longtemps que le fluide à la sortie du premier échangeur (10) est un mélange d'eau et de vapeur, on transforme, par condensation, toute la vapeur en eau et on n'ouvre la vanne de réglage (30) que lorsque le fluide à la sortie du premier évaporateur est de la vapeur pure.
