Fig. 10a shows the power generated or consumed by the
turbines and compressors of the plant at different degree of
supplementary firing. It is observed that at f ¼ 0, the GT produces
58.4 MW power, while 21.5 MW is generated by the steam turbine.
The MC and AC require 21.2 MW and 8.05 MW, respectively, at this
operating condition. As f is increased, the power generated by the
steam turbine increases, and that by the GT correspondingly
decreases. The power consumed by the MC and AC also decreases at
higher f
