Simple reheat cycle

WebbConsider a simple ideal Rankine cycle and an ideal Rankine cycle with three reheat stages. Both cycles operate between the same pressure limits. The maximum temperature is $700^{\circ} \mathrm{C}$ in the simple cycle and $450^{\circ} \mathrm{C}$ in the reheat cycle. Which cycle do you think will have a higher thermal efficiency? WebbIn other words, modify the simple ideal Rankine cycle with a reheat process. Reheating is a practical solution to the excessive moisture problem in tur-bines, and it is commonly used in modern steam power plants. The T-s diagram of the ideal reheat Rankine cycle and the schematic of the power plant operating on this cycle are shown in Fig. 10–11.

Webb9 dec. 2024 · In the ideal Rankine Cycle, pump and turbine operate isentropically, meaning their efficiency is 100% but, in the actual cycle, due to the irreversibilities, there are a few differences. The two main causes for irreversibilities are: – heat loss to the surroundings. – the friction caused between the steam and the cycle components. WebbSetting 90% quality at the low-pressure turbine outlet, CyclePad tells us that we can set the pressure at the outlet of the first turbine to over 2 MPa.
