When Is A Vegetable Oil Said To Be Used

The Cassano d'Adda

In the town of Cassano d'Adda (near Milan) there is a power that the A2 in recent years has changed their traditional power plant operation and has become a central combined cycle thermoelectric . HERE you can find some more information about this facility, including a short video showing the operation and the main structures.

Do not forget the fact that the activity of the plant has made possible the introduction of district heating system in the town itself. The video says the following:

"in a combined cycle power plant in the production of electricity is generated by two generators. The first is directly connected to a gas turbine, the second is connected to a turbine powered by steam produced with the exhaust gases from the combustion process of gas turbine.

Compared to a conventional power plant and then, in a combined cycle plant you have, the same electricity produced, a significant increase in performance with a significant reduction of atmospheric emissions .

production develops in stages: it all starts from the section Turbogas . Here the process of combustion occurs in a system of burners by mixing with air drawn from outside the natural gas. The hot flue gases then expand through the stages of the gas turbine is the heart of the system. Their heat and pressure is converted into energy rotation and then converted into electricity by a generator. The boiler is the steam through the closed loop thermodynamic demineralized water through hot gas still coming out from the gas turbine. Through a flue and chimney gases for the combustion process are emitted into the atmosphere. This phase involves the use of high-pressure steam from the heat recovery steam generator. In the three sections of the kinetic energy of the steam turbine is absorbed by the rotor blades, causing the shaft to generate electricity via the alternator. In the condenser the steam is cooled by water cooling. The condensation obtained is recirculated to supply the heat recovery steam generator. The electricity produced passes through a transformer to raise the voltage that provides for the transport distance, through the high voltage power is delivered for distribution in the city.

The production cycle is monitored and managed from a control room. Great attention is focused on environmental issues, the quantity and quality of air emissions and water conditions. The laboratory is constantly analyzing all the water in the system. The water used for cooling the steam is taken from the Muzza canal near the station. After use is then returned in the same condition except for a slight increase in temperature.
