Preliminary Research for Optimization of Gas-Steam Combined Cycle Cold-End

Abstract:

Aiming at the problem of gas-steam combined cycle cold-end system, the system of the circulating water and condenser are considered as a whole. Based on the basic thermodynamics principles, and considering the coupling characteristics of the output load with gas turbine and steam turbine, providing an analytical method that is used to determine the optimal value of condenser vacuum pressure and circulation water flow rate, the optimum operation mode is obtained with the systematic view. And take a 9F-class circulation unit as an example, the operating mode has been verified by adopting this method. The results indicate that the economy of unit increased after optimization.
