SECTION 1
DESCRIPTION AND DATA
Page 1-1
The Cooper-Bessemer Coberra Peak-Pakgas turbine-driven electric generator unit(Fig. 1-1) comprises a Rolls-Royce Avon 76Gas Generator, Cooper-BessemerRT66 PowerTurbine, Electric Machinery 12,500 KWGenerator with exciter, plus lubricating oilsystems, switchgear and controls to operatethe unit in attended or unattended service.The entire package is furnished complete withweatherproof enclosure to eliminate the needfor a separate building.
The Peak-Pak is designed to operate oneither natural gas or liquid fuel. The change-over from one fuel to the other can be madeeasily with an interchange of fuel manifoldsand eight burner assemblies.
Located at the inlet end of the gas generator is the air inlet plenum chamber. Thisplenum is provided with acoustic panels toattenuate the sound of inrushing air, facilitiesfor introducing a cleaning agent into the gasgenerator inlet air stream and an electricstarting motor. Entrance to the plenum isthrough a door in the end of the enclosure.

Operation of the Peak-Pak is controlledby an automatic-sequential control system.Each step in the sequence must be proved be-fore the next step can be achieved. The unitcan be started, stopped and speed regulated,either up or down, by signals originating fromdevices on the control panel.
Automatic alarm and shutdown devicesare provided as protection against suchadverse operating conditions as overspeed,excessive vibration, high or low temperaturesand high or low oil pressures.
The gas generator, is started by an electricmotor in the plenum chamber which is coupledto the gas generator starter drive mechanismmounted on the front of the compressor shaft.This mechanism is a ratchet and pawl type arrangement that disengages by centrifugal forcewhen the gas generator speed exceeds the starting motor speed. As the starter turns the gasgenerator to a self-sustaining speed, combustionis initiated by two high-energy igniter plugs located in numbers 3 and 6 combustion flame tubes.The starting cycle is originated by the sequentialpanel in the control room.
The gas generator is an axial [low machinewith seventeen stages of compression to pro-vide approximately a 10 to I compression ratio.Air is drawn into the gas generator through theplenum chamber after having passed through asilencer. As the air exits from the compressor diffuser passage, fuel is mixed with asmall portion of the compressed air. Themixture of air and fuel then enters the combustion, or [lame, zone in each of the eightcombustor cans (flame tubes) where it isburned to produce high energy hot gas. Theremainder of the compressed air by-passesthe combustion zone and enters the combustorcans in such a manner as to cool the entiremetal surface of the can. The mixture ofcooling air and burned gases results in a hotgas that is suitable for expansion in the gasgenerator's turbines without imposing thermaldistress on the turbine nozzles and blades. Thecombustion gas is expanded through the turbineblades in the gas generator where a portion ofthe heat energy is converted to rotative powerto drive the gas generator's compressorstages. The turbine shaft and the compressorshaft are coupled together for the direct driveavailability. Only a small portion of the heatenergy is dissipated by the gas generatorturbines. The exhaust gas is still at a highenough (approximately 1111°F and 39 psia)energy level to drive the Cooper-Bessemerpower turbine. Refer to the Rolls-Royce Avon1533-76 Maintenance Manual for a moredetailed description of the gas generator.

The exhaust gases from the gas generatorpass through a cylindrical transition duct tothe power turbine inlet diffuser. Both flangesof the transition duct are sealed by a cast steelsealing ring o[ wedge-shaped section, pressur-ized by the exhaust gas. After passing throughthe power turbine, the exhaust gases are col-lected in an insulated hood and directed toatmosphere.
The Cooper-Bessemer Model RTG6 powerturbine is a single stage impulse reactionturbine. The rotor is overhung in two tilting-pad journal bearings mounted in the bearingcase which is an integral part of the turbinesupport. The bearing case also contains aKingsbury-type thrust bearing to absorb thrustand to limit rotor axial movement.
The rotor shaft and turbine wheel isdynamically balanced as a unit before beinginstalled. A labyrinth seal separates the hotgas section of the power turbine from the bearing housing to protect the bearings from exposure to the hot exhaust gases.
A Woodward governor, mounted on theupper turbine bearing case and an electronictripping device protect the power turbineagainst overspeeding.
