Welcome to Alstom

Both highly versatile and highly efficient,

Alstom’s GT13E2 truly sets the standard.

GT13E2 the latest evolution of gas turbine technology

Alstom’s GT13E2 gas turbine delivers the highest engine efficiency of any conventional

class gas turbine, coupled with long inspection intervals. With millions of fired hours of operation

to its credit, it provides the perfect core for a power plant, designed to produce reliable, competitively

priced electricity.

Utilities and independent power producers face rapid changes – tougher

emissions legislation and fierce competition not least among them. We know our customers need the

high levels of efficiency and performance that the GT13E2 delivers. Its combination of high power

output and high conventional class availability in both simple and combined-cycle plants has made it

first choice with operators across the world.

The GT13E2 offers superior flexibility through two operating modes one

maximises performance, the other maximises operating time between inspection intervals. In addition,

the engine can actively support grid frequency with high response and no extra lifetime factors.

In the power industry, versatility is key. The GT13E2 provides exceptional performance

for a wide range of applications and can operate as a stand-alone turbine in a new or existing power

plant design or as part of a turnkey power plant. Applications cover electrical power generation in base

load, intermediate or peak duty. It can be used in industrial applications such as aluminium smelters

or cogeneration plants, like district heating or desalination. Finally, its modularised and pre-tested

auxiliaries mean it can be brought on-line quickly to support phased plant construction.

03

Operational flexibilityToday’s markets are volatile. To maximise profit, the

GT13E2 can operate in either a Performance Optimised

Mode or a Maintenance Costs Optimised Mode: one

maximises performance, the other maximises operating

time between inspection intervals. With no change in

hardware, plant operators simply respond to market

changes by selecting the best mode online. The turbine

can also handle wide fluctuations in gas composition

while the engine can operate on diesel oil (with or

without water injection for NOx control), with an online

switch-over between gas and oil, even at full load.

Greater efficiency. Meeting the power

Key benefits

Unrivalled efficiency The GT13E2 has the highest open-cycle efficiency of

any conventional class gas turbine, with a high exhaust

energy level providing significant fuel cost savings.

Unlike many advanced gas turbines that come with high

maintenance costs or reduced availability, in creating

the GT13E2 we have optimised our existing proven

technology to add these fuel cost savings without

compromising in other areas.

In an unpredictable energy market, the GT13E2 makes

it simple to switch between operation modes.

04

In an unpredictable energy market, the GT13E2

makes it simple to switch between operation modes.

Easier maintenance / reduced repair workWith the GT13E2, operators can achieve maintenance

intervals of 36,000 Equivalent Operating Hours (EOH)

between hot gas path inspections. This makes the GT13E2

the ultimate choice for operating regimes with a higher

sensitivity to O&M costs and availability.

VersatilityAs well as covering electrical power generation at base

load, intermediate or peak duty, the GT13E2 provides a

cogeneration solution.

Ideal for industrial applications such as aluminium smelters,

district heating or desalination plants, it makes use of exhaust

heat to generate thermal energy for a range of applications.

It has been designed for superior performance under all

conditions including extreme heat or cold.

Continuous enhancementWe are constantly evolving the GT13E2, keeping it at the very

cutting-edge of turbine technology. We do this by making

incremental improvements.

The GT13E2 had three upgrades so far, perfectly illustrating

the way we make these enhancements: every upgrade to our

turbine blading compressor and combustor has increased

performance, boosted operational flexibility and reduced

maintenance time.

Higher performance industry’s high demands

05

Maintenance-free welded rotor Alstom’s welded rotor was first introduced for steam turbines in

1929 and has been operating successfully in our gas and steam

turbines every since. The rotor is welded from forged discs that

ensure high stiffness with two-bearing support. This design

eliminates maintenance work such as restacking and disk

replacement or factory rotor overhaul. It also removes the need

for ‘major overhauls’.

Low-stage loaded compressorThe 16-stage compressor with its low stage loading yields a

high surge margin and high reliability. Three rows of variable

guide vanes control airflow efficiently, increasing part load

efficiency and starting reliability, with improved environmental

turndown.

Annular combustorA fully annular combustion chamber distributes the

circumferential temperature evenly while avoiding problem

zones such as cross-firing tubes or transition pieces. Alstom’s

annular combustion systems also do not need any ‘combustor

inspections’ as for can-annular systems. This reduces the

amount of maintenance leading to higher availability.

Dry low NOx AEV burnerOur AEV (Advanced EnVironmental) burner technology is

a further refinement of the EV burner, which has operated

successfully for several millions of hours throughout the Alstom

gas turbine fleet, with a long burner life, no maintenance

between hot gas path inspection and low emissions. The

AEV burner gives the benefit of dry low NOx combustion for

operation with different natural gases, with the option to run

with liquid fuel as an alternative.

TurbineAdvanced aerodynamics and multi-convective cooling schemes

contribute significantly to the GT13E2’s outstanding efficiency.

The design of the first turbine stage, combined with thermal

barrier coating and conservative firing temperatures, allows

extended inspection intervals of up to 36,000 EOH. All Inconel

738 conventional cast turbine airfoils and heat shields ensure

long parts life and allow for full, cost-effective refurbishment.

Axial exhaust systemFor power producers limited on space, the straight-line

arrangement of our gas turbine and heat recovery steam

generator (HRSG) facilitates compact plant layouts. By

eliminating the turning elbow, plant owners also benefit

from reduced back-pressure and turbulence at the HRSG

inlet, improving performance in both simple and combined-

cycle mode.

and performanceDelivering outstanding results

Extended inspection intervalsOne of the key advantages of the GT13E2 is its ability to

operate with extended inspection intervals for low fuel cost

applications or in schemes where fuel is provided by the power

off-taker (Tolling or Energy Conversion schemes). The GT13E2’s

Optimised Operation Mode allows for 36,000 equivalent

operating hours between Hot Gas Path inspections. Plant

operators can receive this benefit with only a very marginal

reduction in efficiency and output.

EfficiencyIn simple cycle turbines, the GT13E2 provides the highest

efficiency in its class, delivering unrivalled performance in

markets where fuel costs are higher or fluctuate regularly.

Its Performance Optimised Operation Mode also offers the

lowest Cost of Electricity (CoE) when fuel prices rise.

The importance of flexibilityThe GT13E2 has been designed to deliver high operational

flexibility. This includes the ability to switch between operation

modes online. If demand is seasonal or fuel prices are volatile,

this ability to switch modes without changing hardware brings

a crucial advantage, maximising profits.

PerformanceThe GT13E2 delivers exceptional performance coupled with low

emissions at full and part load with low turndown. The world’s

most reliable heavy-duty gas turbine, it offers a fast start and

high load gradients as well as a frequency response in the wide

load range. Plant operators benefit from its high fuel flexibility

and power augmentation options.

Seamless integrationSimple.

Alstom engineers work

in partnership with our

customers to meet every

requirement.

Developing, building, and operating a profitable gas turbine

power plant goes far beyond selecting the best components.

A key aspect is integration, which can substantially enhance

flexibility and performance.

As a leading EPC contractor, we approach every integration

project with the following list of requirements for our gas

turbines:

The gas turbine should be designed for simple and cost

effective integration into the overall plant.

In-depth, comprehensive user information should be

readily available.

Application consulting should be available when required.

Plant owners add the following requirements to the list:

Operational flexibility to support plant dispatch requirements

such as quick start-up, fuel flexibility, black start, power

augmentation, air inlet cooling.

Operational stability to accommodate sudden load changes,

active grid frequency support, black grid restoration, partial

or global load rejection.

An efficient Operation & Maintenance regime.

With the Alstom GT13E2 gas turbine, all the above come

as standard.

The GT13E2 is backed by Alstom’s plant operating and

maintenance service expertise, with a portfolio including any

level of service from spare parts delivery up to full operation and

maintenance. Operational support is also available on a 24/7

basis with the on-line Alstom Monitoring and Diagnosis System

(AMODIS).

The GT13E2 is the result of years of Alstom experience in

gas turbine plant design and construction. This experience

goes back to the world’s first commercial gas turbine plant in

Neuchâtel, Switzerland, in 1939. Today, Alstom is the leading

EPC contractor worldwide, with technology for all plant

components in house.
