INDUSTRIAL STEAM TURBINES PRODUCT SOLUTIONS
GRT Steam Turbine
Geared Steam Turbine
With more than 100
years of experience in
steam turbine technology,
Alstom offers a highly
efficient and compact
steam turbine that is
optimised for a truly tailored
solution.
Highly efficient and compact
With high reliability and proven technologies, the GRT steam turbine provides
optimised solutions for efficient and flexible power and steam production. It
features a highly flexible modular concept that comes in a Plug-and-Play
package to reduce installation and commissioning time and costs.
The GRT modern design has been inspired by the demand of today’s power
plant operators who require flexibility and reliability while providing the
highest efficiencies. Our turbine offers bespoke steam extraction options
thanks to its modular architecture, allowing it to perfectly fit the industrial and
power markets.
