Abstract: Modern thermal power plants based on classical thermodynamic power cycles suffer from an upper bound efficiency restriction imposed by the Carnot principle. This disclosure teaches how to break away from the classical thermodynamics paradigm in configuring a thermal power plant so that its efficiency will not be restricted by the Carnot principle. The power generation system described herein makes a path for the next generation of low-to-moderate temperature thermal power plants to run at significantly higher efficiencies powered by renewable energy. This disclosure also reveals novel high-performance power schemes with integrated fuel cell technology, driven by a variety of fuels such as hydrogen, ammonia, syngas, methane and natural gas, leading toward low-to-zero emission power generation for the future.
Abstract: A heat-driven refrigeration/heat-pump system includes at least one vapor expansion stage and at least one vapor compression stage, a condenser, and an evaporator, while the power consumption of the compression stages is fully supplied by the power output of the expansion stages. In the system, a vapor absorber/generator unit is adopted, such that at least one expansion stage is fed by the vapor from the generator, and at least one power stage; compression or expansion, delivers its output stream to the absorber instead of to the condenser. In the new arrangement the expansion stages produce surplus power, facilitating a supplementary refrigeration loop between the evaporator and the condenser to which there is no direct expense of heat from the generator, thereby improving the overall performance of the system.
