Conversions, Modifications and Upgrades

Ansaldo Thomassen is a company with extensive servicing

and improving GE heavy-duty gas turbines because of

its OEM heritage. With nearly 50 years of accumulated

knowledge and expertise we offer the market special

engineering solutions. Our conversion, modification and

upgrade solutions are based on increasing your gas

turbine power output, improving heat rate and reduce

emissions.

Compressor Upgrades

The compressor is a key part of the gas turbine. It makes

sure the air intake is stable and optimal to be led into the

combustion chamber. This means that the pressure is as

high as possible for more expansion in the turbine part, the

temperature of the air is as low as possible which leaves

more room for expansion of the air and the amount of air is

optimally high. These characteristics can all be optimized

with compressor upgrades. All modifications made to the

Conversions,Modificationsand Upgrades

compressor are meant to optimize airflow, temperature

and pressure resulting in a power increase and improved

heat rate.

Firing Temperature Upgrade

A huge part of the energy supplied by the gas turbine is

a result of expansion of air under the influence of heat

of combusted fuels in the combustion chamber. By

increasing this heat the power output can be increased, in

the meantime lowering the heat rate. Mutually beneficial.

ThomELT

To be able to withstand the increased pressure and

temperature and the increased wear which automatically

follows these extreme circumstances, your gas turbine

will need an upgrade with a ThomELT package. This

Thomassen Extended Lifetime-kit is a package consisting of

a few adaptations to certain parts of the gas turbine. These

adaptations include liner stops and heat resistant coatings.

Hot Gas Path Upgrades

Primarily the hot gas path upgrades include a new and

clean effect on the parts. This restores the original output

and heat rate of the machine as if it were new. Also, the

parts which are exposed to more extreme temperatures

and pressures are improved by using special extra heat

resistant alloys. These alloys are resilient enough to

withstand the even more extreme circumstances resulting

from the firing temperature upgrade. Furthermore several

advanced sealing options are available.

Emission Control Upgrades

All emission control options are focused on lowering

NOx-emission. Within the category of emission control

upgrades we have several options: our own Thomassen

Dry Low NOx system as well as water injection and steam

injection options.

Thomassen Dry Low NOx system

The best possible option for NOx-reduction is ourThomassen Dry Low NOx system (T-DLN). This

Thomassen-design for the dry low NOx-system is based

on, and backwards compatible with, the OEM DLN-

system and can guarantee emissions below 25 ppm NOx

(emissions as low as 9 ppm are to be expected) complying

with nearly all environmental restrictions. Next to limiting

the NOx-emissions CO emissions drop as well, something

that does not happen with water or steam injection. More

information about our Thomassen Dry Low NOx system is

available on our technical product sheet.

Control System Upgrades

The latest generation of heavy-duty gas turbine controllers,

Ansaldo Thomassen TC-7, is covering every aspect of

turbine performance. Based on the proven design of

Simatics PCS7, the TC-7 is a digital control system that

takes advantage of an open-architecture design and

nonproprietary hardware, keeping maintenance costs to a

low while ensuring maximum performance. Furthermore

we are able to service your Speedtronic gas turbine

control system.

Gas Turbine Remanufacturing

Within our gas turbine remanufacturing program weintegrate custom solutions such as emission reductions,

control system upgrades and extended lifetime programs,

for example on the gas turbine rotor.

Ansaldo Thomassen

The power of thought is a remarkable thing. A brilliant mind can easily generate great ideas.

Like service solutions that benefit energy installations. Thats why we combine the engineering

capacity from our OEM background with the open-mindedness of an indepenedent service

provider. Giving tou sound advice and optimal service when it comes to repairing, reconditio-

ning, upgrading or servicing GE type gas turbines.

A single source solution offering the best of both worlds. We call it OSP, Original ServiceProvider. A great concept to engineer power installations worldwide to new levels. Because

improving our clients energy output sparks our minds as well. Our service and sales centers

are located in the Netherlands, Italy, India, the United Arab Emirates and Venezuela.

We Set Power in Motion.
