4 GE Gas Turbines
GE10 Gas Turbines
The 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 for both Power Generation and Mechanical
Drive applications.
The cases are horizontally split and the rotor has a disk architecture. The combustion system
consists of a horizontally positioned single can.
The GE10 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 gaseous fuels, including Low
BTU gas and hydrogen. The GE10 engine design has been highly refined based on the extensive
experience gained in operating in all types of environments.
There are over two hundred PGT10/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 flexibility make the GE10 a cost-effective choice for all applications.
Axial 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.
The cold-end drive configuration guarantees reduced flange movement during gas turbine
thermal transients. A patented GECC-1 aluminum ceramic coating is provided for application in
marine environments.
Combustion System and Emissions
The combustion system consists of a single, slot-cooled combustion chamber assembly that
permits easy maintenance of the hot gas path.
This combustion chamber can burn a wide range of fuels, from liquid distillates to residuals, to all
gaseous fuels including low BTU gas. The broad fuel capability of this
combustor is due to the variable geometry design patented by GE. Guaranteed NOx levels of
either 15 or 25 ppmvd @ 15% O2 are available over a broad load range. A DLN Dual Fuel version
(liquid + gas fuel) is also available.
