THE POWER PLANT TECHNOLOGY


The Azito Power Plant represents more than a third of the electricity production in Côte d’Ivoire e.g. 1,900 GWh per year. Since the beginning of operation in 1999, the total energy produced by the AZITO Power Plant amounts to about 8,000 GWh. The availability and the capacity are always above the guaranteed values. This performance is achieved thanks to the competent and dedicated operating team, as well as the quality and the technology of the installed equipments.

The GT 13 E2 gas turbines in AZITO Power Plant are characterized by:
 

  • a main supply with gas and oil in emergency;

  • a thermal block composed by an axial air compressor on 21 stages, delivering pressurized air in the combustion chamber and a 5 stage turbine with an axial exhaust;

  • an annular combustion chamber equipped with low nitrogen oxide emission burners;

  • an air cooled alternator for power supply;

  • a cooling of the auxiliaries by a close circuit cooler with demineralized water.


The final technical configuration of the Azito Power Plant

The AZITO power plant will include at its final stage a combined cycle unit composed of:

  • Two GT 13 E2 gas turbines;

  • Two heat recovery boilers and a steam turbine with a condenser;

  • Cooling towers;

  • Fuel supplying system (gas and oil in emergency);

  • A demineralization plant;

  • Water pumping stations, electric equipment and a centralized control room.
