AE94.2 Gas Turbine
-
The AE94.2 Gas Turbine meets customer needs in terms of
performance, emissions and operational/fuel flexibility for
intermediate-class gas turbines, by delivering a competitive and
cost-effective package based on established techno-logy. The latest
continuous improvements have been made avai-lable for previous
releases through a retrofittable package. The special AE94.2K
version of this gas turbine can also burn low-BTU fuels and high H2
content gas.

A benchmark in flexibility
The AE94.2 gas turbine is a benchmark for both operational and
fuel flexibility. The ability to adapt rapidly to provide the
requested grid power is becoming more and more important:
startupandloadingtime:fullspeednoloadreached in less than 5 minutes
and baseload conditions about15minuteslater.Fastloadinggradient

bestdynamicperformanceduringgridsupport:40MWin few seconds is a
well proven result on several units.The AE94.2 is the best solution
to satisfy increasing market demand of greater fuel flexibility:

load range and carried out in as little as a few minutes in certain
conditionsmixedoperation(concurrentcombustionofgasandoil): this
mode is particularly useful when neither fuel gas nor fuel oil can
be supplied in sufficient quantities to achieve the base load.
Low emissions for challenging targets
* Dry gases, 15% O2 **30 mg/Nm3 option available
The VeLoNOx burner, designed by Ansaldo Energia to reduce NOx
emissions in fuel gas mode, achieves NOx emissions levels lower
than 30 mg/Nm3 with a small dera-ting in power output.
Recognised excellence in commissioning and after sales
services
Ansaldo Energia offers a full range of services and qualified
personnel for erection and/or supervision, start-up and te-sting of
your AE94.2 gas turbine. The availability of standard arrangements
and in some cases packaged solutions ensures rapid, problem-free
erection, start-up and commissioning. The Ansaldo Energia Service
Organisation provides tech-nical assistance services worldwide,
available 24 hours a day, 7 days a week, in the fields of
maintenance, spare parts supply and preventive maintenance
programs, so en-suring that customers are in the best position to
achieve op-timum operation.Continuous process improvements
guarantee the best assistance for our customers: for example, the
la-test maintenance procedures include extended spare parts stocks
and streamlined logistics.
AE94.2K - Matching customer fuel flexibility needs with a
tailored solution
Ansaldo Energia has been working on the use of low caloric
valuegasinheavydutygasturbinessince1997.Thespe-cial AE94.2K
version, specifically designed for low BTU fuels
(syngas,steelmill,blastfurnacegases,biomass,etc.),canburnfuelswithLHVintherange8-13MJ/kgandlower.The
combustion system, including the modification to allow it to burn a
wide range of fuels, has been patented.
Proud of our worldwide references decades of experience:
Our AE94.2 fleet is installed worldwide, and has an excellent
track record of robustness, operational flexibility and
durability.
