WebCh 10. Rankine Cycle. A steam power plant operates on an ideal reheat-regenerative Rankine cycle with one open feedwater heater, one closed feedwater heater, and one reheater. The fractions of stream extracted from turbines and the thermal efficiency of the cycle are to be determined. All the components in the cycle operate at steady state. WebIf now the temperature of the feed water be raised to 200 degrees Fehr., we shall require from the boiler furnace for each lb. of water evaporated 1,1992 — (200 — 32) = 1,081.2 thermal units, which equals a gain of 1,171.2 — 1,031.2 x 100, 1,171.2 equals 11 per cent.
