Objective
The aim of the project was to demonstrate that wind energy electricity generation can be used to powered thermic and electrical components in a desalination plant.
The system is energy self-sufficient and self-controlled in order to be installed especially in remote localization without technical supervision personal.
Design, manufacturing and installation of all part of the plant has been carried out with many difficulties due to the bureaucracy rules and authorizations, so the project spred over many years.
Until today SASTIL never received to regular operation with authorization direct collection of sea water discharge of salin concentrated output into the sea.
Due to incorrect location and due to the low speed and direction variability of the wind was not possible to make significant demonstration testing phase and valid measurements data collection.
The data collected with a wind sensor sited near the wind turbine at 20m height, we have verified that exist poor wind condition to guarantee regular plant operation.
Start up testing demonstrated that the rotor rarely shows required speed to operate the electrical generator.
Wind turbine electrical generator is directly connected to three electrodes in the desalination plant boiler. The control system changes the level of the process liquid in the boiler according to the wind speed so that the quantity of sea water to be desalinated in the plant is automaticaly modified.
The plant has been designed in order to combine two different technologies : multi-effects process and steam compression through the use of an ejector.
The wind turbine selected for the project is a AIT 03 by Aeritalia (today Alenia). It has an horizontal axis, two blades, 10 m diameter up-wind rotor connected to synchronous generators rated to 25 KW mounted on a 10 m high tower for wind speed in the range 5 and 18 m/s. The site originally selected to the demonstration project had an average speed of 5.5 m/s and the wind turbine was able to produce 25700 kWh per year.
