Let's assume that we generate electrical energy by means of a turbine generator. Before the steam enters a reversible adiabatic turbine, it must be raised to 10.000 kPa pressure and 450 ºC. As the steam leaves the turbine, its pressure drops to 150 kPa and a temperature of 100 C. The flow of steam in the turbine is 57 kg / s. In the meantime, your ambient temperature was measured as 25 ºC and pressure as 100 kPa. Considering these conditions, how much exergy does the steam have when entering and leaving the turbine? How much power does the turbine generate? How much power can be produced from this turbine and what is the second-law efficiency of this turbine? Calculate.
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.
