Gas Turbines GE Oil & Gas manufactures a complete line of gas turbines for all major Oil & Gas Industry applications. They are installed in natural gas plants, gas compression stations, oil booster stations, petrochemical plants and power generation and cogeneration plants worldwide. GE Oil & Gas has long-standing experience in manufacturing gas turbines dating back to 1961 when a manufacturing agreement was established with General Electric (U.S.A.) to complement the existing portfolio of products for the petroleum and petrochemical industries (reciprocating and centrifugal compressors, gas engines, pumps, valves, etc.). A proven combination of sound design and quality assurance techniques places these gas turbines among the world’s most reliable. Basic models produced by GE Oil & Gas cover the 5,000 to 124,000 kW power range. They can be provided in simple or regenerative cycles for mechanical drive or generator drive applications. Extensive research and development, advanced design procedures, modern manufacturing technology and on-site experience are behind the success achieved by GE Oil & Gas gas turbines. 1 The GE5 uses enhanced nozzle and bucket materials similar to those used in aircraft engines. has greatly improved overall compressor performance without sacrificing reliability or mechanical integrity. with a capability range from 50% to 105%.

The large chord. In addition. broad-blade compressor blades have low stresses and the unique ability to withstand damage by small foreign objects as well as to maintain high performance in spite of normal wear and contamination. The stator casing is horizontally split for ease of assembly. Iron castings give dimensional and thermal stability to maintain good radial tip clearances for maximum power and efficiency. Each individual wheel undergoes inspection and is X-rayed for material flaws.Axial Compressor The compressor rotor is made of separately forged wheels (all models except the GE5 and part of the GE10 which have a solid forged rotor). each wheel is balanced individually and the rotor is balanced on three planes. The blades are held in the compressor rotor and stator rings by dovetail platforms. The GE5 and GE10 compressors have variable geometry. Several compressor designs are available covering pressure ratios in the 7-14 range and air flows from 20 to 400 Kg/sec with 15-17 stage configurations.

The stainless steel blades provide excellent corrosion resistance and good internal dampening characteristics. First Stage Nozzle The complete first stage nozzle assembly consists of airfoil-shaped vanes which are contained between an inner and an outer sidewall. relatively thick nozzle partition trailing edges provide increased strength and oxidation resistance. Cooled air from the compressor discharge is directed through the body of the individual nozzle partitions and out holes near the trailing edge. A key feature of the firststage nozzle is the air-cooled partition which extensively increases nozzle life. This not only cools the metal. 13 . but blankets the trailing edge with a film of air. Seals in the turbine shell prevent leakage of combustion gases around the nozzle from the inlet to the exhaust. Compressor discharge air is fed to these sealing rings through orifices in the shell. again providing longer nozzle life.GAS TURBINE MAIN COMPONENTS date the effects of thermal expansion caused by the hot gases and keep the assembly properly aligned in the gas path. Additionally. Further wheel protection is provided by radial seals on the first-stage bucket shanks that restrict hot gas leaks into the wheel cavities. This is accomplished by opening the second stage nozzles to their maximum angle. Compressor bleed air is used to cool the wheels and maintain relatively low temperature levels.Buckets and Wheels The long shank bucket design lowers the turbine wheel rim a substantial distance below the hot gas path. The high thermal resistance of the shank results in a considerable temperature drop between the hot bucket vane and the wheel dovetail. Second-stage Nozzles (variable angle) The second-stage variable angle nozzle is a unique feature of Nuovo Pignone/General Electric gas turbines. OVERSPEED LIMIT Overspeeds which may occur principally with loss of load can be limited with the variable nozzles and turbine operation maintained without tripping. It is utilized on the second stage of the two-shaft gas turbines (except GE5) and has the following advantages over a fixed nozzle. thus reducing temperature levels and gradients in the turbine wheel and the dovetail area where rotating stresses are high. HEAT RATE The heat rate can be decreased substantially at light loads by maintaining 14 . Thus the turbine develops more power in starting. MAXIMUM OUTPUT High pressure turbine speed can be held at the rated value as ambient temperature changes. the pressure drop across the high pressure turbine is maximized.
