WebThe ideal regenerative Rankine cycle The first part of the heat-addition process in the boiler takes place at relatively low temperatures. ... •The combined cycle is the gas-turbine (Brayton) cycle topping a steam-turbine (Rankine) cycle, which has a higher thermal efficiency than either of the cycles executed WebThe pressure ratio of the Brayton cycle, r p is defined as, Then The processes 1-2 and 3-4 are isentropic. Hence, We get, or Work delivered by the cycle is given by W= h Q 1 . Increasing Q 1 can increase work done by the cycle . Since the Turbine blade material cannot withstand very high temperature, T 3 and hence Q 1 is limited
