WebThe reheat is performed by spraying additional fuel into the exhaust gases. This is possible since after the first combustion, the exhaust gases still contain enough Oxygen (remember that the mass ratio between air/fuel is > 50). If the number of stages is indefinitely increased, the Brayton cycle with intercooling, reheating and Reheating in gas turbine is the method of extracting extra work output from the gas turbine in which the exhaust gas from the main turbine (High-pressure turbine) is heated and then expanded further into the next low-pressure turbine. The exhaust gases leaving the combustion chamber (CC in the figure), still … See more The following are some effects of reheating on the gas turbine:- 1. The reheating raises the temperature of the turbine exhaust. 2. It helps to increase the work output from the gas turbine. 3.
