A-cycle B-heat source (fuel, nuclear etc) C-cooling water D-electrical generator 4 Vapor power systems Pump Boiler Turbine Condenser ? ? ¢ ¢ generator - Water reservoir 5 Rankine cycle -Several fundamentals to analyze real power plant systems 1. Conservation of mass 2. Conservation of energy 3. 2 nd law of thermodynamics 4. Property values Let’s introduce Rankine cycle which models Part A of slide 3 and slide 4 6 Rankine cycle Principle work and Heat transfer for each component -Positive work/heat transfer in the direction of arrows -stray heat transfer neglected -KE and PE ignored -steady state Turbine High P and high T through Turbine And generate W 0 = ? ? − ¡ ? + ݉ (?...
