AE64.3A GAs TuRBINE

AE64.3A Gas Turbine combustion chamber tiles and turbine bladesA quick-start Gas Turbine for more flexibilityAnsaldo Energia’s AE64.3A is a quick start gasturbine: full speed is reached in less than 5 minutesand baseload conditions about 20 minuteslater. Fast-loading gradient procedures can reducethis time to about 15 minutes.The AE64.3A was the first annular gas turbine inthe world to be operated in fuel gas premix modeacross the entire load range, including GT run upto full speed no load. This important achievementsignificantly improves operations, because it greatlysimplifies the management of load rejectionand transient modes in general, as well as improvingthe ability to provide grid support from anyload. For these reasons, fuel gas premix modehas been extended to the entire annular fleet, includingboth AE64.3A and AE94.3A models.Addressing a growing need for fuel flexibility, thegas turbine can be fired with different fuels: bothnatural gas and liquid fuel oils can be used.The fuel switch from gaseous to liquid, and viceversa, can be performed very reliably in the midto-highload range.A specifically redesigned onboard fuel distributionsystem with flexible hoses ensures operationaland layout optimization, reduces erection andcommissioning times and improves maintainabilityLow emissions for challenging targetsRecognised excellence in commissioning andafter sales servicesAnsaldo Energia offers a full range of services andqualified personnel for erection and/or supervision,start-up and testing of your AE64.3A gas turbine.The availability of standard arrangements and insome cases packaged solutions ensures rapid,problem-free erection, start-up and commissioning.The Ansaldo Energia Service Organisation providestechnical assistance services worldwide, available24 hours a day, 7 days a week, in the fields of maintenance,spare parts supply and preventive maintenanceprograms, so ensuring that customers are inthe best position to achieve optimum operation.Continuous process improvements guarantee thebest assistance for our customers: for example, thelatest maintenance procedures include extendedspare parts stocks and streamlined logistics.Proud of our worldwide references - decades ofexperience:Our AE64.3A gas turbines, and the previous AE/V64.3version, are installed worldwide and have anexcellent track record of robustness, operationalflexibility and durability.1,600,0001,400,0001,200,0001,000,000800,000600,000400,000200,0001995AE64.3A & AE/V64.3 CumulativeEquivalent Operating Hours1997Dec. 2011: 1 500 000 EOH199920002001Years2003200520072011AE64.3AFUEL GASPREMIXDRYPREMIXDRYFUEL OILDIFFUSION45% water/fuelNOx [mg/Nm 3 ] *50250 120CO [mg/Nm 3 ] *3030 30AE64.3A Gas Turbine package - typical arrangement* Dry gases, 15% O 2
