Please find the highest thermal efficiency possible, while remaining within the boundaries. What is required: -Power produced must be at least 60 Mega Watts -Thermal efficiency must be greater than 36% -Back-work ratio must be smaller than 48% Assume: -air is the working fluid -specific heats vary with temperature (use table A-17) -Compressor inlet is at 1atm and 300k -the combustion process is isobaric and is modeled as a heat exchanger -Turbine exhaust is the same pressure as compressor inlet Compressor specifics: -Max volume flow rate (m^3/h) = 600,000 -Max outlet pressure (atm) = 12 -Isentropic efficiency = 90% Combustion chamber and gas tubine specifics (Note these come as a set) -Max pressure = 16.7 atm -Max temp = 1500 (celcius) -Turbine isentropic efficiency = 92% -Max heat rate = 230MW
Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
Please find the highest thermal efficiency possible, while remaining within the boundaries.
What is required:
-Power produced must be at least 60 Mega Watts
-Thermal efficiency must be greater than 36%
-Back-work ratio must be smaller than 48%
Assume:
-air is the working fluid
-specific heats vary with temperature (use table A-17)
-Compressor inlet is at 1atm and 300k
-the combustion process is isobaric and is modeled as a heat exchanger
-Turbine exhaust is the same pressure as compressor inlet
Compressor specifics:
-Max volume flow rate (m^3/h) = 600,000
-Max outlet pressure (atm) = 12
-Isentropic efficiency = 90%
Combustion chamber and gas tubine specifics (Note these come as a set)
-Max pressure = 16.7 atm
-Max temp = 1500 (celcius)
-Turbine isentropic efficiency = 92%
-Max heat rate = 230MW
