Abstract
The evaporative gas turbine cycle is a new high-efficiency power cycle that has reached the pilot plant testing stage. This article presents the construction of a mathematical model for thermodynamic simulation of part-flow evaporative gas turbine cycle including steam injection. The maximum deviation of predicted performance results by this model from available data in literature was 1 per cent. Then, changes in configuration of this cycle have been investigated. Configuration changes concern using feed water heater and injection of saturated vapour instead of superheated vapour to the humid air in the cycle. This investigation shows that both these strategies were in the direction of improvement of efficiency and specific work of cycles (intercooled and non-intercooled). The results obtained from this research show that using spray cooler as the intercooler in the intercooled cycle offers interesting perspectives. In addition, the optimization of part-flow evaporative gas turbine (PEvGT) cycles in the systematic manner is presented and discussed.
