Rankine Cycle • Generate electricity • Drive major equipment • Vapor power cycle
Rankine cycle • Fossil fuel • Wood • Garbage • Nuclear reaction
Rankine Cycle • Water • Cheap • Available • Stable • Nontoxic • High heat capacity • High heat transfer rate
Rankine cycle • Water pump • Steam generator • Turbine • Condenser
Rankine cycle • Performance • Thermal efficiency • bwr • Steam rate • Heat rate
Rankine Cycle • Water is the working fluid in an ideal Rankine cycle. Inlet to turbine 1600 psi & 1100oF. Condenser pressure is 1 psi. Mass flow rate of steam is 1.4 x 106 lbm/h. Cooling water temperature is increased from 60 • Find the rate of heat transfer in the steam generator (kW), thermal efficiency (%), and the mass flow rate of the cooling water when it enters the condenser at 15oC & exits at 35oC.

Rankine Cycle • Inlet to the turbine is 1600 psi & 1100oF. Condenser pressure is 1 psi. Mass flow rate of steam is 1.4 x 106 lbm/h. Cooling water temperature through the condenser is increased from 60oF to 80oF. • Find the net power, Btu/h, thermal efficiency of the cycle, and mass flow rate of cooling water, lbm/h.
