In a cogeneration plant, 10° kg/h of steam at 80 bar, 480 °C expands in the h.p. turbine to 10 bar. From the exhaust 4 × 10° kg/h of steam is extracted for process heating. The remaining steam expands in the 1.p. turbine to 0.08 bar. Saturated liquid at 0.08 bar leaving the condenser is pumped to 9.5 bar where it mixes with the condensate from the process heater leaving at 9.5 bar, 120°C. The entire flow is then pumped to 80 bar. The isentropic efficiencies of the turbines and the pumps are 86% and 80%, respectively. Determine (a) Copyrighted ma Analysis of Steam Cycles 101 the heating load, in kJ/h, (b) the power developed by the turbines, in kW, and (c) the rate of heat transfer in the steam generator, in kJ/h. [Ans. (a) 9.53 kJ/h, (b) 236500 kW, (c) 3.032 × 10° kJ/h]
