Question 22: The superheated steam powers a steam turbine for the production of electrical power. 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 efficiency of 90%.

It is requested:

Define the Power Plant Schematic
Analyze the steam power system considering the steam generator system in the attached figure
Determine the electrical power generated and the thermal efficiency of the plant
Perform an analysis on the power generated and thermal efficiency considering a variation in the steam fractions removed for regeneration

##Data:

The steam generator uses biomass from coconut shells to produce 4.5 tons/h of superheated steam;
The feedwater returns to the condenser at a temperature of 45°C (point A);
Monitoring of the operating conditions in the steam generator indicates that the products of combustion leave the system (point B) at a temperature of 500°C;
Fuel consumption was 0.189 kg/s;
The thermal efficiency of the generator was 63.2%;
Energy losses totaled 0.3637 MW;
Temperature and pressure of superheated steam are 200°C and 0.1 Mpa, respectively.
