My Question: In the steam plant problem#2, the reheater developed a leak and it was decided to run the plant bypassing the reheater. Determine the thermal efficiency and steam flow rate to develop the same power output.Problem 2 (In a reheat cycle steam enters the high-pressure turbine at 40 bar and 400C. It expands isentropically to 6 bar and is reheated at constant pressure to 400C. This steam is expanded isentropically in the low pressure turbine to the condenser pressure of 0.1 bar. Calculate the thermal efficiency and steam consumption for 10 MW output.)

A reheat steam cycle has 13,580 kPa of throttle pressure at the turbine inlet and a 37.50308414 atm reheat pressure, the throttle and reheat temperature of the steam is 1302 R, condenser pressure is 4.3 kPa. Determine the difference between the simple Rankine cycle efficiency and the reheat Rankine cycle efficiency, in percent.

Q.8 In a regenerative steam cycle employing one open feed heater, the steam is supplied to the turbine as dry saturated at 40 bar, and exhausted to the condenser at 0.35 bar. The intermediate bleed pressure is 10 bar. Sketch the layout of the plant and show on the temp | entropy diagram the pressure under gone by the steam, neglecting the pump works, calculate: A. The mass of steam bled from the turbine per Kg of steam leaving the boiler. B. The thermal efficiency of the plant. C. The thermal efficiency of the plant without feed heating. D. The heat rate in (kJ/kW.hr) for the plant with and without feed heating.
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…
