U.S. Patent Specifications

The method of increasing the efficiency and output horsepower of a gas turbine which comprises introducing the motive gas to the turbine at a temperature substantially in excess of a safe operating temperature for the stator and rotor blades of said turbine and simultaneously spraying water into the gas stream adjacent the turbine inlet to form a water film on the rotor and stator blades, said water being in a finely dispersed condition having an approximate size of 60 to 100 microns when it leaves the spray nozzle and sprayed in amounts insufficient to materially lower the gas temperature in the time the gas passes to the blades, and in amounts great enough to keep the outside of the blades wet, whereby the sensible temperature of the blades is at least several hundred degrees Fahrenheit lower than the entering gas temperature.
