### Superheated steam powers a steam turbine for the production of electrical energy. The steam expands in the turbine and at an intermediate expansion pressure (0.1 Mpa) a fraction is extracted for a regeneration process in a surface regenerator. The turbine has an isentropic efficiency of 90%Design the simplified power plant schematicAnalyze it on the basis of the attached figureDetermine the power generated and the thermal efficiency of the plant### Dados in the attached images • Steam flow rate: 4.5 tons/h = 1.25 kg/s• Fuel flow rate: 0.189 kg/s• Boiler thermal efficiency: 63.2%Energy losses: 0.3637 MW• Turbine efficiency: 90%Superheated steam at turbine inlet:200°C, 0.1 MPaFeedwater temperature at condenser exit:45°C FUELSUPERHEATED VAPORCOMBUSTION AIR↑C
