At steady state, a device receives a stream of saturated water vapor at 210°C and discharges a condensate stream at 20°C, 0.1 MPa while delivering energy by heat transfer at 300°C. The only other energy transfer involves heat transfer at 20°C to the surroundings. Kinetic and potential energy changes are negligible. What is the maximum theoretical amount of energy, in kJ per kg of steam entering, that could be delivered at 300°C?
