A wet compression power augmentation apparatus and method for effectively adding a mass flow of water particles to a gas turbine preferably by use of a spray rack group assembly having at least one spray rack water pipe and at least one spray rack water nozzle. Water mass flow is added preferably in increments such that operationally-induced thermal transients within the gas turbine are sufficiently minimized to preserve the structural integrity of the gas turbine. Monitoring of the temperature profile of fluid-cooled rotor blades in the turbine section with an optical pyrometer to detect clogging of cooling pathways in those rotor blades from impurities in the liquid added through the wet compression, monitoring of temperature in proximity to the gas turbine compressor inlet to guard against the possibility of icing, a deformation measurement device, preferably a laser emitter and laser target measuring system mounted to the exterior of the gas turbine housing to detect deformation in the housing of the gas turbine from associated cooling effects of the wet compression technique, and periodic addition of heat and humidity, preferably steam, to the compressor inlet are disclosed.

[ What is claimed is:] [1.] A method for augmenting the net output of a gas turbine characterized in operation by periods of continuous use exceeding about 4 hours in duration in driving a generator or compressor, the gas turbine having an axial-flow multistage compressor having an inlet for acquiring a working fluid comprising air, the method comprising the steps of:providing liquid water comprising liquid droplets to the working fluid acquired by the axial-flow compressor to reduce the temperature increase of the working fluid caused by compression to achieve an increase in the net output of the gas turbine available to drive said generator or compressor as measured against the net output of the gas turbine under comparable conditions but without liquid water provided, andsaid method including the further step of providing heat and humidity to the working fluid to allow continued power augmentation during periods when the temperature of the working fluid would otherwise drop to a level which would allow detrimental ice formation to occur in the inlet.
