Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
148 words
A POWER PLANT APPARATUS COMPRISING: A VAPOR GENERATOR OPERATIVE TO SUPPLY STEAM ONLY AT LOW PRESSURE; A PRESSURIZED WATER NUCLEAR REACTOR AS A HEAT SOURCE FOR SAID VAPOR GENERATOR WITH THE PRESSURIZED WATER FLOWING AS THE HEATING MEDIUM IN HEAT EXCHANGE RELATION THROUGH SAID VAPOR GENERATOR; A FEEDWATER PUMP CONNECTED TO SUPPLY WATER TO SAID VAPOR GENERATOR AT LOW PRESSURE; A STEAM COMPRESSOR RECEIVING STEAM FROM THE VAPOR GENERATOR AND OPERATIVE TO INCREASE THE PRESSURE OF THE STEAM PASSING THERETHROUGH; A SEPARATELY FIRED SUPERHEATER CONNECTED TO RECEIVE THE HIGH PRESSURE STEAM ONLY FROM THE COMPRESSOR; SAID SEPARATELY FIRED SUPERHEATER BEING FIRED WITH FOSSIL-FUEL, AND THE PRESSURE OF THE STEAM WHERE HEAT FOR SUPERHEATING IS BEING ABSORBED BEING HIGHER THAN THE PRESSURE OF THE WATER WHERE HEAT FOR EVAPORATION IS BEING ABSORBED AND A STEAM TURBINE CONNECTED TO RECEIVE HIGH PRESSURE HIGH TEMPERATURE STEAM FROM THE SEPARATELY FIRED SUPERHEATER.
