GEAR BOX DETAILS:
The supplied Gearbox is a Reducer type gearbox, which is designed with a service factor in accordance with AGMA 6011 H-98, The high speed shaft of the gearbox in coupled to the turbine by means of a flexible coupling. The low speed shaft end of the turbine is coupled directly to the alternator. Torque is transmitted at the low speed end due to Frictional force generated by the butting of the two shafts.

CONDENSING SYSTEM DETAILS:
Purpose of System
The purpose of the condenser and evacuation system is
 To build up and maintain a necessary vacuum for the turbine exhaust steam.
 To condensate exhaust steam flow from the turbine.
 To perform vacuum braking and shorten the turbine coasting down time.
 To receive internal drainage from the turbine plant and this way return it to the process.

System Function
The main condenser is a tube heat exchanger,Exhaust steam from the turbine is condensed in the tube bundle and the condensate is collected in the Condenser hotwell, the condensate level controlled and always kept below the tube bundle. Subcooling of the condensate is prevented by the design.
The purpose of the vacuum- breaking valve to reduce the condenser vaccum by admitting air to the condenser and tube casing.
A rupture disc in the condenser shall prevent in the turbine exhaust and condenser system.
With turbine internal drain lines flash tank is connected to condenser hotwell.
Manholes for internal inspection are provide on the water boxes and the condenser shell.

Weight of the equipment (empty) : 22000 KGS
Weight of the Equipment (Operating) : 34000 KGS
Weight of the Equipment (flooded) : 42000 KGS

Steam Jet Air Ejector:
Condenser vacuum is built up and maintained with a steam jet air ejector unit.

A high capacity steam Ejector (Hogging ejector) is used to build up the vacuum in the main condenser during starting procedure.
During operation in the two stage steam ejector is used to maintain the condenser vacuum operating steam is condensed in the stages of the ejector condenser, which is cooled by condensate from the main condenser (inter condenser) Air and other non-condensed steam are then evacuated from the second stage.(after condenser)

Main Components:
1. Hogger ejector with silencer
2. Y – Stage Ejector I
3. Y – Stage Ejector II
4. Z – Stage Ejector I
5. Z – Stage Ejector II
