Heat cycle facility
The heat cycle facility includes: a first vaporizer that vaporizes a first liquid heating medium by combusting fuel; a first motive power generator that generates motive power by using as a drive fluid a first gas heating medium obtained at the first vaporizer; a condenser that condenses the first gas heating medium discharged from the first motive power generator by heat-exchanging the first gas heating medium for a second liquid heating medium; a circulator that pressurizes the first liquid heating medium obtained at the condenser and supplies the pressurized first liquid heating medium to the first vaporizer; a second vaporizer that produces gaseous ammonia by heat-exchanging the second liquid heating medium for liquid ammonia; and a supplier that supplies the liquid ammonia to the second vaporizer.
1. A heat cycle facility comprising:
a first vaporizer that vaporizes a first liquid heating medium by combusting fuel to obtain a first gas heating medium;
a first motive power generator that generates motive power by using as a drive fluid the first gas heating medium obtained at the first vaporizer;
a condenser that condenses the first gas heating medium discharged from the first motive power generator by heat-exchanging the first gas heating medium for a second liquid heating medium to obtain the first liquid heating medium;
