20090158739 | GAS TURBINE SYSTEMS AND METHODS EMPLOYING A VAPORIZABLE LIQUID DELIVERY DEVICE - Systems and methods utilizing turbines, including a compressor turbine with a vaporizable liquid delivery device, are presented. A compressor turbine uses the evaporation of a vaporizable liquid at or near thermal equilibrium from the vaporizable liquid delivery device during the compression. The vapor created thereby typically carries the thermal energy discharged after the gas turbine cycle. The amount of liquid vaporized during compression, the length of time vaporization takes, the proximity to thermal equilibrium at which vaporization occurs, the amount of thermal energy recovered by recuperation, and the temperature at the inlet of the combustion chamber are generally interrelated parameters that can be controlled to increase efficiency. | 06-25-2009 |
