HMW-1 Regenerative steam power plant shown in figure below employs two feed heaters which are optimally placed such that cycle has the maximum thermal efficiency. The mass of steam generated is 16 kg/s. The feed water leaves each heater as saturated liquid at corresponding bleed pressure. Neglect the pumps work and find: a. Cycle thermal efficiency. b. Specific steam consumption. c. Mechanical efficiency of the turbine-generator gearing unit. Draw the equivalent (T-s) diagram considering an ideal cycle. 70 bar 450°C Gearing unit Generator 15 MW Turbine Super heater Boiler Condenser 0.07 bar Open heater Closed heater Pump Pump Throttling Valve
