Thermal power station Regina Margherita
The thermal power station Regina Margherita was a large power station for the production of electricity, preserved at the
History
Designed at the Polytechnic University of Milan, it was built by combining a steam engine from the Franco Tosi company of Legnano and a pair of alternators from the Brown Boveri company.[2]
The power station opened on November 9, 1895; the ceremony was attended by
Museum
In 1958 Egidio e Pio Gavazzi proposed to donate the power plant to the
Description
The station contains two parts: thermal, consisting of a steam engine with two horizontal cylinders, and electric, consisting of two alternators and two exciter dynamos. There is also an electric control panel and a lighting system with 8 lamps.[1] The machine is activated by an electric motor, connected to it by a chain which encircles a pulley, and it no longer produces current.
Technique
This machine is an example of a compound steam engine.[1]
Although it relied on the finest nineteenth-century technologies, the "Regina Margherita" was not a cutting-edge piece of machinery. Ten years before its making, the Englishman Sir Charles Algernon Parsons had already invented the steam turbine. In the latter device the force of the steam acts directly on the blades of the wheel, producing the rotation necessary to operate the alternators. The steam turbine is more efficient than a cylinder and piston system because it reduces energy waste from the transformation of alternating motion into rotary motion and from the transmission of movement through connecting rods, cranks and belts.[2]
