Turbine Details :

Gas Turbine Generator (GTG) & Auxiliaries System :

The heavy-duty high performance Gas turbine is characterized by high firing temperature, superior fuel efficiency and ability to burn vide spectrum of fuels. The Gas Turbine is designed for natural gas firing only. The high exhaust temperature of Gas Turbine is ideally suited to efficient combined cycle operation.

The GTG unit includes the following installed in prefabricated enclosures:

Multi-stage, axial flow, corrosion protected compressor
combustion system - DLN or Standard combuster
Three stage gas turbine
Alternator, totally enclosed water to air cooled
Generator Auxiliary Compartment and Bus fed static excitation system
Lube oil and Gas Accessory Compartment
Electric Motor starting system
Off-line Compressor water wash skid
NOx control Water injection module with inlet air evaporative cooling.
Generator and Lube oil Water cooling module
Packaged electronic and electrical control compartment (PEECC) and
Turbine control panel
Self cleaning inlet air filter
CO2 Fire Protection System

Generator :
The 2-Pole, 11 kV, 3phase synchronous generator is a totally enclosed water to air-cooled unit with brushless excitation system.

GTG Auxiliary Cooling System :
GTG Lubricating Oil Coolers and generator Air Coolers are proposed to be cooled by DM water in the Closed Circuit mode (primary circuit), which shall be cooled by Auxiliary Cooling Water Pumps in the secondary circuit.
