Summary of System Retrofits System Retrofits Chilled water Install new control panels for chiller 1-3 system Remove the flow control valves and primary pumps Shut off the isolation valve on the bypass pipeline Boiler system Install two VFDs for FD fans of the two boilers in operation Install two VFDs for the feed water pumps CAV AHUs Lock the inlet guide vane
fully open, shut off the reheat valve and fully open the bypass damper permanently.
High Gravity (g) Combustion: In the high-g UCC concept, a cavity runs around the outer circumference of the turbine inlet guide vanes
(TIGV), as seen in Fig.
Hence, the compressor speed, inlet guide vanes
, and the hot gas bypass (HGBP) are set up with a microprocessor-based controller.
In these installation, suction throttling or variable inlet guide vanes
are used to provide means of control.
Navy air-cushioned landing craft known as LCACs, to develop the ASE50, a 3.8-megawatt industrial gas turbine that will incorporate the air-staged DLE system, a new air inlet, variable inlet guide vanes
, a higher-efficiency impeller, an improved diffuser, an accessory gearbox, and Allen-Bradley state-of-the-art turbine controls.
At a second major inspection (64,000 firing hours) all the following components will be changed: combustion liners, transition pieces, first- and second-stage nozzles, first- and second-stage buckets, first-and second-stage shrouds, inlet guide vanes
, axial compressor blades (stator and rotor), and bearings.
The modulating inlet guide vanes
are made of corrosion-resistant GTD-450 stainless steel to extend their performance life.
