SGT-A65 TR (Industrial Trent 60) gas turbine highlights

Due to its independent 3-shaft design, this gas turbine is highly flexible, offering high power output and fuel effiency with minimal drop-off at part-load and reduced-speed conditions.

For a simple cycle SGT-A65 TR package, the start-up sequence time is designed to be less than 7 minutes – from pressing the start button to reaching full base load. This includes an allowance for a simple cycle exhaust system purge.

The SGT-A65 TR boasts the most extensive mechanical drive experience in its class. It is ideally suited to meet the higher power, variable speed demands required, for instance, for natural gas liquefaction, gas transportation, or gas induction for oil recovery.

One of the most efficient gas turbines on the market, the SGT-A65 TR provides up to 66 MW in simple cycle service at 42.5% efficiency. With its cold start capability and high cyclic life, this engine can rapidly add power to the grid to compensate for fluctuating and variable renewable and other energy sources – making it your ideal solution for peaking markets.

The SGT-A65 TR consists of 8 engine modules for easy maintenance. Each module is pre-balanced to make it completely interchangeable.

The inlet spray intercooling (ISI) system improves the gas turbine's performance at ambient temperatures above 7 °C (52 °F) better than comparable inlet cooling technologies with similiar peformance enhancement – while minimizing additional water consumption and auxiliary load.

Ingenious design to the core

The SGT-A65 TR is designed for flexibility so that you can use the same engine for power generation as well as mechanical drive service, without any changes. The mechanical arrangement uses three coaxial independently rotating shafts contained within a carcass of axially joined circular cases.

 

 

SGT-A65 TR packages

The package is designed for quick installation and easy maintenance in the field. The package contains all components and subsystems that we have carefully selected and optimized to support the SGT-A65 TR gas turbine:
Core engine, enclosure, base frame, air intake, exhaust collector, engine control system, fuel metering skid, lubricating systems, starter system, vibration monitoring system, firefighting system, package ventilation system, instrumentation, gearbox (if needed).

 

 

The SGT-A65 TR fires up

The SGT-A65 TR exhaust hood can be rotated in 3 directions, which allows customized configuration depending upon the available space. The power density of high aeroderivative power in a small and lightweight package is well suited for land use with more green open space.

Liquid fuel operation

Due to the aeroderivative heritage, the SGT-A65 TR can operate on liquid fuels without an EOH (equivalent operating hour) penalty. In fact, the SGT-A65 TR has shown complete liquid operation without performance or component life degradation.

Designed to meet stringent environmental requirements

The SGT-A65 TR Dry Low Emissions (DLE) engine uses eight radial staged combustors to successfully run in part-load operation while still complying with NOₓ and CO regulations.

NOₓ emissions:  ≤ 25 ppmvd on fuel gas (with WLE and DLE, at 15% O₂)
