12 Auxiliaries the ideal equipment to round out the package We pay attention to the details. We not only offer you the core components for flexible and efficient packages, we also provide the auxiliaries necessary for economical and reliable operation. To minimize field work during assembly and maintenance, the auxiliary systems and associated piping are designed and manu factured to allow easy access and require fewer connections. Air intake system Ambient air is guided and filtered to the compressor inlet with an option for a selfcleaning (pulse) filter with automatic dust removal. Inlet air conditioning options are available that include evaporative cooling and inlet chilling for increased output on hot days. Inlet heating options are available for extreme cold environments. Exhaust gas system Exhaust gas is guided from the gas turbine via the diffuser to the turbine plant s stack or to a combined cycle plant s heat recovery steam generator (HRSG). A bypass stack option is available for combined cycle plants for switching between combined cycle mode and simple cycle mode during operation. 12

13 Electrical system The electrical package contains equipment necessary for sequencing, control, and monitoring of the gas turbine and generator. This includes the gas turbine control system, motor control centers, generator protective relay panels, fire protection system, battery bank, battery charger, and dry-type transformers. Oil systems The oil systems consist of a lube oil (LO) package and a hydraulic oil power unit (HPU). The LO package provides clean, filtered oil for lubricating and lifting the gas turbine and generator bearings, and provides lubrication for the turning gear. The LO skid consists of the lube oil reservoir, LO pump, and lift oil pumps and provides a support structure for the LO cooling system (fin-fan air or water cooled). An all-weatherproof lube oil enclosure option is available for cold or dusty environments. The HPU provides mediumpressure hydraulic oil to operate the gas fuel stage throttle valve, the inlet guide vane actuator, and the variable guide vane actuators. Starting system The starting system consists of an air cooled static frequency converter (SFC) and a turning gear system. The turning gear can be remotely and automatically operated. The turning gear system rotates the rotor at 120 rpm during shutdown to facilitate a uniform cooldown. During start-up, the turning gear rotates the rotor to remove bow and facilitate a smooth start. The turning gear also provides the breakaway torque to accelerate the gas turbine to the speed needed to engage the SFC. The SFC accelerates the gas turbine to ignition speed, and after successful ignition the SFC will assist in accelerating the unit to rated speed. Compressor water wash skid The compressor water wash skid is provided for online and offline compressor cleaning. It features an AC motordriven pump, piping, valves, strainer junction box, cabling, flowmeter, and detergent storage tank. Everything is assembled on a portable skid for greater flexibility. Enclosures The gas turbine is housed in an enclosure with easy disassemble/assemble walls for quick engine access. Fire protection The fire protection system gives a visual indication of actuation at the local control panel. The fire suppressant system provides total protection of the turbine enclosure and the electrical control package. There are many other options available to meet your project specific needs. 13
