ABSTRACT:
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.
