1 Vapor Power System Sistem Pembangkit Tenaga Uap

2 Komponen Utama sim

3 Model thermodinamika Siklus uap pembangkit tenaga uap bekerja berdasarkan siklus ideal thermodinamika : siklus Rankine

4 Siklus Rankine

5 Kerja dan heat transfer

6 Performance parameter Thermal efficiency Bwr, back work ratio

7 Contoh soal Steam is the working fluid in an ideal Rankine cycle. Saturated vapor enters the turbine at 8.0 MPa and saturated liquid exits the condenser at a pressure of MPa. The net power output of the cycle is 100 MW. Determine for the cycle (a)The thermal efficiency, (b)the back work ratio, (c)the mass flow rate of the steam, in kg/h, (d)the rate of heat transfer,, into the working fluid as it passes through the boiler, in MW, (e)the rate of heat transfer, from the condensing steam as itpasses through the condenser, in MW, (f)the mass flow rate of the condenser cooling water, in kg/ h, if cooling water entersthe condenser at 15C and exits at 35C.
