Abstract

Cette invention concerne un procédé de fonctionnement en charge partielle consistant à réguler l'apport de fluide diluant, de fluide combustible et de fluide oxydant dans des cycles thermodynamiques au moyen de diluant pour augmenter la température d'entrée turbine (TIT) et le rendement thermique d'un fonctionnement en charge partielle à des valeurs supérieures à celles obtenues lors du fonctionnement en charge partielle (dans l'état antérieure de la technique) des cycles de Brayton, des cycles de Brayton voilés ou des cycles fonctionnant avec une faible amenée de vapeur ou avec une amenée de vapeur maximale. Le procédé de fonctionnement en charge partielle peut permettre de réguler la température d'entrée turbine (TIT) au niveau de la conception par régulation de l'un et des deux éléments parmi lesquels un liquide et/ou de l'eau provenant d'un fluide gazeux dans une plage comprise entre une charge totale et une charge inférieure à 45%. Ce mode de réalisation permet à la fois de réduire les charges de fonctionnement et d'obtenir des rendements plus élevés, ainsi que des coûts d'exploitation réduits grâce à l'utilisation de l'eau, de la vapeur et/ou du CO2 en tant que diluants, par rapport à un simple fonctionnement par cycles.
