Fuel Gas System A typical gas fuel configuration employs shutoff valves for safety reasons and metering valves to control the machine load and CO/NOx emissions. Depending on the level of DLN performance requested, two or three metering valves are needed in order to control gas injection in the various parts of the combustion chamber. operation of the unit is supplied, including: • Unit control panel (on GT skid) • Motor control center (on GT skid) • VFD for gas turbine starting • Generator control and protection panel • DC panel & battery charger Unit Control Panel The GE10 control system is standardized to assure a high degree of integration between the turbine and the generator. The system is based on the GE Fanuc RX3i PAC System platform with remote I/O modules. The Bently Nevada 1701 is installed for the acquisition of data from seismic probes and for humming detection. The control, monitoring and tuning of unit parameters can be performed remotely. Remote data acquisition does not interfere with normal site operations. Control CAB An integrated control cab containing all electrical panels for control and • Batteries • On site monitoring system The cab is provided with an air conditioning system, normal and emergency lighting, a smoke detection system and manual fire suppression bottles. Air Filter The air filtration system consists of a self-clearing vertical cartridges filter house, an inlet duct and a silencer. This system also provides an anti-icing function without any additional hardware. Filter inspection and replacement of filter cartridges are facilitated by gangways and ladders that are included as part of the scope of supply. Package Arrangement The gas turbine enclosure consists of a separate structure and panels mounted on a base plate. Access doors are included for normal maintenance operations and inspections. The ventilation system for internal cooling of the package consists of two 100% axial fans. The enclosure includes fire & gas detection systems and an automatic CO2 -type fire fighting system. The enclosure guarantees a sound pressure level lower than 85 dBA at 1 m. An 80 dBA version is available upon request. The GE10-1 package is designed specifically for power generation applications and is optimized to minimize plant dimensions and to reduce maintenance cost and time. The single lift architecture minimizes the site installation and commissioning lead time. The integrated control cab eliminates civil works for the control room and site wiring activities. Available Options • Dual Fuel DLN version (liquid + gas fuel) • 6.0 kV Electric Generator • 80 dBA sound pressure level package • Indoor version • H2O oil cooler • STD exhaust duct (12 m) • Lubrication stand-by pump • Control cabinet located alongside the unit • Additional Pre-Engineered BN1701 for complete vibration monitoring

Open the catalog to page 2Axial Compressor The compressor is a high Performance, eleven-stage axial flow design with a 15.5:1 pressure ratio derived from GE Aircraft Engine transonic flow aero design technology. The rotational speed is 11000 rpm with a mass flow of 47 kg/s. The antisurge margin exceeds 25%. Advanced 3D airfoils are used for vanes and blades, and the first three rows of stator blades are adjustable to optimize operability. Being a cold-end drive configuration guarantees reduced flange movement during gas turbine thermal transients. A patented GECC-1 aluminum ceramic coating is provided for...
Open the catalog to page 4The GE10 is a heavy-duty gas turbine in the 12MW range, available in either a single or a two-shaft configuration. It is the evolution of the field proven PGT10 and incorporates the latest in aerodynamic design, and compact and versatile package arrangements. The GE10 engine design has been highly refined based on the extensive experience gained operating in all types of environments. There are over two hundred PGT10A/GE10 units running under conditions ranging from the cold of Alaska and Siberia to the heat of the desert and the humidity of the tropics. Its efficiency and operational...
Open the catalog to page 5Engine Characteristics The well proven GE10-1 gas turbine is a heavy duty single shaft engine that has accumulated a large number of fired hours, and has leveraged the experience of the previous PGT10. The cases are horizontally split and the rotor has a disk architecture. The combustion system consists of a horizontally positioned single can. The GE10-1 is available in both Diffusion Combustion System and DLN (Dry Low NOx) versions (15/25 ppmvd NOx) and is able to burn a wide range of liquid and gas fuels, including Low BTU gas and hydrogen.

Open the catalog to page 7Maintainability GE10 maintenance can be carried out either “on-site” or at an authorized shop. An engine exchange maintenance approach can be adopted to maximize the unit availability. Enclosure doors, and flexible piping and electrical connectors permit the engine to be easily removed, and a back-up engine quickly installed to minimize the plant down time. The engine is provided with borescope holes for periodic inspection of the internals, and the combustion chamber can be disassembled without removal of any of the engine casings. GE gives the highest priority to engineering and field...
