METEO 300 Lecture Notes - Lecture 30: Steam Turbine, Rankine Cycle, Thermal Efficiency
Document Summary
Me 300 - lecture 30 - cycles: steam power plant. Review of the rankine cycle (steam power plant) Determine the maximum possible thermal efficiency for an industrial steam power plant operating with a high pressure of 1 mpa and a low pressure of 5 kpa. The power plant operates on a rankine cycle with the steam entering the turbine as a saturated vapor and water entering the pump as a saturated liquid. http://direns. mines- paristech. fr/sites/thopt/en/res. State 1: = 0 and 1 = = 5 kpa. 1 = = 137. 5 kj/kg and 1 = = 0. 4762 kjkg k. State 2: 2 =1 = 0. 4762 kjkg k and 2 = = 1 mpa. State 3: = 1 and 3 = = 1 mpa. State 4: 4 = = 5 kpa and 4 =3 = 6. 5850 kjkg k. Mixture, = 0. 7715 4 = 2007. 1 kj/kg. Compressors, turbines, and pumps are isentropic in this case since we want to determine the maximum possible thermal efficiency.
