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…
A power plant operating in a Reheat Rankine Cycle produces steam at 3 MPa, 600oC in the boiler. It keeps the condenser at 45oC by transfer of 10 MW out as heat transfer.
