A steam power plant of 110 MW capacity is equipped with regenerative as well as reheat arrangement. The steam is supplied at 80 bar and 55°C of superheat. The steam is extracted at 7 bar for feed heating and remaining steam is reheated to 350°C, and then expanded to 0.4 bar in the L.P. stage. Assume indirect type of feed heaters. Determine : (i) The ratio of steam bled to steam generated, (ii) The boiler generating capacity in tonnes of steam/hour, and (iii) Thermal efficiency of the cycle. Assume no losses and ideal processes of expansion.

2. A steam power plant of 110 MW capacity is equipped with
regenerative as well as reheat arrangement. The steam is supplied at 80
bar and 55°C of superheat. The steam is extracted at 7 bar for feed
heating and remaining steam is reheated to 350°C, and then expanded to
0.4 bar in the L.P. stage. Assume indirect type of feed heaters.
Determine : (i) The ratio of steam bled to steam generated, (ii) The
boiler generating capacity in tonnes of steam/hour, and (iii) Thermal
efficiency of the cycle. Assume no losses and ideal processes of
expansion.
