2 .6 A 0 kg/ teady upply of aturated-apor team at 500 ka i required for drying a wood pulp lurry in a paper mill. It i decided to upply thi team by cogeneration, that i, the team upply will be the exhaut from a team turbine. Water at 0 C, 00 ka, i pumped to a preure of 5 Ma and then fed to a team generator with an exit at 00 C. What i the additional heat tranfer rate to the team generator beyond what would hae been required to produce only the deired team upply? What i the difference in net power? Deired exit State : = 500 ka, at. ap. => x =.0, = 5.9 C h = h g = 78.7 kj/kg, = g = 6.8 kj/kg-k Inlet State: 0 C, 00 ka h = h f = 8.9 kj/kg, = f = m /kg Without Cogeneration; he water i pumped up to 500 ka and then heated in the team generator to the deired exit.
