WebUntitled Document. LECTURE 20. 20.1 Ideal Reheat Rankine Cycle. Increasing the boiler pressure increases the thermal efficiency of the Rankine cycle, but it also increases the moisture content of the steam. To overcome the problem: - modify the simple ideal Rankine cycle with a reheat process. - expand the steam in the turbine in two stages ... WebThe above section states that increasing the boiler pressure can increase the thermal efficiency of the Rankine cycle, but it also increases the moisture content at the exit of the turbine to an unacceptable level. To …

Significant increases in the thermal efficiency of gas turbine power plants can be achieved through reducing the amount of fuel that must be burned in the combustion chamber. This can be done by transferring heat from the turbine exhaust gas, which is normally well above the ambient …
WebThe idea behind double reheating is to increase the average temperature. It was observed that more than two stages of reheating are generally unnecessary, since the next stage increases the cycle efficiency only half as much as the preceding stage. Today, double reheating is commonly used in power plants that operate under supercritical pressure. WebThis increases the value of T m — the temperature of heat addition and keeps the evaporator, superheat reheat portion from 7 to 3 closer to the flue gas line ae. This results in higher cycle efficiency. 2. It improves the final dryness of steam (from 4′ to 4) and reduces turbine blade erosion. 3. It increases cycle work by increasing the ...
