Definitions

  • the present invention relates generally to power plants and more particularly to power plants that use combustion turbines that are powered by hydrocarbon gases, such as natural gas or propane.
  • Vaporization is conventionally done by burning some of the fuel or by warming the liquid against some other heat source.
  • Air pressure is affected by altitude, weather-induced changes in barometric pressure, and pressure losses associated with the air flow through inlet ducts, filters, etc.

Abstract

L'invention concerne un combustible à base d'hydrocarbure liquide pour un groupe moteur, vaporisé contre un fluide d'échange thermique, refroidissant ainsi le fluide. Un circuit (32) de recirculation permet au fluide refroidi d'être redirigé en arrière pour être à nouveau refroidi lorsque désiré. Le fluide refroidi est utilisé pour refroidir l'air d'entrée d'une turbine (16) à combustion. Une partie du fluide refroidi est périodiquement dirigée vers le fond d'un réservoir stratifié (12), d'où le fluide peut être retiré lorsque le besoin ou la valeur de refroidissement de l'air d'entrée est plus élevé. Le fluide est réchauffé tandis qu'il refroidit l'air d'entrée, et peut être utilisé pour vaporiser du combustible supplémentaire, ou redirigé vers la partie supérieure du réservoir stratifié (12).
