Steam from a turbine with inlet pressure 30 bar and temperature 350°C is bled at 5 bar and 1 bar to supply a two-stage regenerator to heat up condensate leaving the turbine at 0.08 bar. In each stage, the condensate is heated up to the saturation temperature of the bled steam and the bled steam itself condenses completely. Remember: in a regenerator, there is no contact between the two streams, only heat exchange. of Consider the amount of steam bled at 5 bar and 1 bar, respectively, to be m¡ and m2 kg per steam supplied to the turbine. For the first stage, m¡ kg of bled steam at 5 bar heats each kg of condensate arriving from the second stage without any contact (that is, regeneration). Then, m¡ kg of condensate derived from the bled steam drains into the steam space of the second stage at 1 bar without heat loss. The combined drain from the second stage at 1 bar consists of mi+m2 kg per kg of steam supplied to the turbine. The combined drain is cooled to the condenser temperature…

Power generation using steam is one of the most common method which can be found around the world. In these type of power plants, steam goes through a basic thermodynamic cycle called Rankine cycle which is shown in the following figure. Steam flow Boiler Qin Pump Wout Win Condenser •Qout For the proper operation of the cycle, water should be pumped to the boiler using pump which required work input (Wm) generate steam and then high pressure steam is fed to the turbine. By extracting the energy from high pressure steam, turbine is producing work output (Wout). Because of this, the steam pressure is reduced and low pressure steam is flowing into the condenser. Condenser removes heat energy from steam further (Qout) and steam is converted into liquid water. The liquid water can be pumped into the boiler again and the cycle continues. Performance of a Ranking cycle can be evaluated by using thermal efficiency (nth)which is determined from; the cycle. Heat energy should be supplied to the…
