[1]. [2]. [3]. [4]. [5]. Calculate the heat and work transfers, cycle efficiency and specific steam consumption for a steam power plant which operates on the Carnot Cycle from a pressure of 20 bar to 0.035 bar. 1500 kg/hr of dry saturated steam at 20 bar is supplied to a turbine and the condenser pressure is 0.035 bar. If the plant operates according to the Rankine cycle, find: work output if work by feed pump is neglected; feed pump work and work ratio; heat supplied; Rankine efficiency; (a) (b) (c) (e) (f) SSC; heat transferred to evaporator cooling water and rate of flow of cooling water if the rise in temperature is 5.5 K. Compare these results with the corresponding values for Carnot cycle in Question 1. Recalculate Question 2 by taking degree of superheat as 200°C. Reconsider Question 3 and this time the plant operates with superheat. Calculate efficiency, ssc and dryness factor for steam coming out from second stage turbine. Assume that steam coming out from first stage turbine is dry saturated and is reheated to its initial temperature i.e. 412.4°C. Compare All the results with the corresponding values for Carnot cycle in Question 1. Give your comments on the results findings. [1]. [2]. [3]. [4]. [5].
