Method for closed-loop magnetic fluid power generation by making use of latent heat of vaporization and cyclic power generation system

Abstract

The invention discloses a method for closed-loop magnetic fluid power generation by making use of latent heat of vaporization and a cyclic power generation system. A high-temperature high-pressure supercritical-state working medium is subjected to adiabatic expansion through a supersonic expansion passage, latent heat of condensation is released along with cluster type gas condensation to be further converted into fluid kinetic energy to finally obtain high-speed fluid, the high-speed fluid enters a plasma generation section to form conductive fluid which cuts magnetic induction lines to generate induced electromotive force for power generation, the fluid is condensed for recovery by a condenser after power generation, and the recovered fluid is pressurized by a high-pressure pump and heated by a heater to reach the high-temperature high-pressure supercritical state again to start a next cycle. Compared with a traditional power generation system, the cyclic power generation system has the advantages that a magnetic fluid power generation passage and a supercritical expansion passage for a steam turbine are replaced, the problem of compelled adoption of high steam discharge temperature due to blade cavitation caused by steam condensation in the steam turbine is solved, and accordingly the temperature of a cold source can be further lowered, and thermal cycling efficiency is improved.
