The gas turbine inlet air chiller has a combined cycle power system having a gas turbine and one or more bottoming cycle expansion turbines for driving one or more generators, compressor inlet air to the gas turbine is cooled. An extraction is taken from the distillation condensation sub-system of the Kalina cycle and throttled to a lower pressure, with a corresponding temperature drop for supply to a low pressure evaporator in heat exchange relation with ambient air flowing to the compressor inlet to cool the ambient air. The partially evaporated multi-component mixture exiting the low pressure evaporator is returned to the spent vapor stream from the low pressure expansion turbine for combination therewith and condensation. Consequently, compressor inlet air inlet to the gas turbine is cooled, thereby increasing mass flow and turbine output.

A gas turbine flow meter is provided in one exemplar embodiment, having a magnetic induction signal producing means disposed within the gas flow path of the meter and having unique weir type seals for protecting the rotor bearings from contamination, thus substantially prolonging the life of the rotor bearings. The magnetic induction coil and magnets utilized in the signal producing means are radially spaced significantly closer to the rotor axis of rotation than the rotor blades for substantially increasing the mechanical advantage of the meter and improving its low pressure, low flow-rate signal producing capability.

Gas turbine repair services include component removal, gas turbine rotor overhaul, speed balancing, component repairs, reverse engineering, failure analysis thermal barrier coating & overlays. It also provides component machining, inspection & analysis, on-site support and project management.
