AE94.3A - A high-performance
and competitive Gas Turbine
The F-class AE94.3A gas turbine, the most
advanced in Ansaldo Energia’s product portfolio,
is based on well proven, reliable Ansaldo Energia
technology.
The AE94.3A model allows Ansaldo Energia customers
to equip their combined cycle power
plants with gas turbines that are fully competitive
in terms of all market drivers in the large gas turbine
segment: efficiency, power output, reliability,
operational flexibility and emission levels.
Continuous product improvements are combined
with the traditional reliability and robustness of
Ansaldo Energia products to offer customers a
unique and balanced value package based on innovation
and reliability.
• 24 hybrid burners (premix operation) for
natural gas and light oil
• Axial exhaust
• Film cooled blades/vanes with advanced
materials
• Easy maintenance features (all blades and
vanes are replaceable with rotor in place, and
the hot gas path can be inspected with no need
to open the turbine)

A quick-start gas turbine for more flexibility
Ansaldo Energia’s AE94.3A is a quick start gas
turbine; baseload conditions can be reached in
less than 30 minutes.
The AE94.3A fitted with the VeLoNOx burner
delivers high operational flexibility and longer operating
life: the Load Ramp has been optmized and
the Minimum Environmental Load has been reduced
to 42% of the baseload, while keeping NOx
and CO emissions low.

turbine. The availability of standard arrangements
and in some cases packaged solutions ensures
rapid, problem-free erection, start-up and commissioning.
The Ansaldo Service Organisation provides
technical 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 ensuring that customers are in
the best position to achieve optimum operation.
Continuous process improvements guarantee the
best assistance for our customers: for example,
the latest maintenance procedures include extended
spare parts stocks and streamlined logistics.
AE94.3A Gas Turbine rotor
The AE94.3A gas turbine operates in fuel gas
premix mode across the entire load range, greatly
simplifying the management of load rejection and
transient modes in general, as well as improving
the ability to provide grid support from any load.
Addressing a growing need for fuel flexibility, the
gas turbine can be fired with different fuels: both
natural gas and liquid fuel oils can be used.
The fuel switch from gaseous to liquid, and vice
versa, can be performed very reliably in the midto-high
load range.
A specifically redesigned onboard fuel distribution
system with flexible hoses ensures operational
and layout optimization, reduces erection and commissioning
times and improves maintainability.
Low emissions for challenging targets
Proud of our worldwide references – decades of
experience
Our AE94.3A fleet is installed worldwide and has
an excellent track record of robustness, operational
flexibility and durability.
