Novel cycles: humid air cycle systems

P. Chiesa,     Politecnico di Milano, Italy


This chapter is devoted to gas turbine cycles where water vapor is mixed with air to increase specific power output and efficiency. Basic configurations like steam injected, recuperative water injected and humid air turbine cycles are considered. Mass and thermal balances are reported for each plant, thermodynamic merits and technological drawbacks are illustrated and their performance compared on the basis of homogeneous assumptions. Problems related to operating commercial gas turbine engines in humidified air cycles are also discussed.
