(KJ/KW-h) ENTROPY: is the measure of uncertainty or randomness. (J/K) Enthalpy : is a measure of the total energy of a thermodynamic system. (J)BASIC TERMINOLOGIES (cnt..): BASIC TERMINOLOGIES ( cnt ..) EFFICIENCY: tells how better the system is. Thermal Efficiency: Heat equivalent of mech. energy transmitted to turbine shaft/Heat of coal combustion. Overall Efficiency: Heat equivalent of electrical output/Heat of combustion of coal.RANKINE CYCLE OF SUB-CRITICAL POWER PLANT: RANKINE CYCLE OF SUB-CRITICAL POWER PLANTPowerPoint Presentation: RANKINE CYCLE OF SUPER-CRITICAL POWER PLANTPowerPoint Presentation: BRAYTON CYCLEPowerPoint Presentation: Brayton Cycle with Compressor inter-coolingPowerPoint Presentation: Brayton Cycle with Water InjectionPowerPoint Presentation: Common power cycle thermal efficiencies Simple Steam Cycle: 25%-35% Generator steam at high pressure exhaust steam from steam turbine to condenser. Simple Gas Turbine: 30%-35% Gas turbine driven generator with exhaust to atmosphere. Combined cycle: 50%-60% Gas Turbine driven generator with exhaust used to make high pressure steam, and high pressure steam used to generate additional electricity in steam turbine. Gas Turbine-Process Steam: 75%-85% Gas turbine driven generator with exhaust used to make low pressure steam for process.PowerPoint Presentation: FEW QUESTIONS How to increase efficiency in case of Rankine Cycle? Why we can’t reduce vacuum in condenser below 0.1 absolute pressure?PowerPoint Presentation: In thermodynamics, the triple point of a substance is the temperature and pressure at which three phases (for example, gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium .
