  • 2015.04.17 Chili I SECURISE A FRAGILE AND EXPENSIVE RESSOURCE: MOLYBDENUM

     

    The largest pit copper mine in the world is to be found in Chile, 200 km from Antofagasta.  It is owned by CODELCO who produces more than one fifth of the global annual ore volume and has resources for two hundred years.

    The company also mines other precious ores such as molybdenum. Its primary use is in stainless and high alloy steels. A fragile and expensive resource, molybdenum was widely used during WW1 as its addition, even in small quantities, enhanced the strength and hardness of the steels. [+]

How it works : System description

System Description

The NO-BREAK KS® is such a simple piece of equipment that one might think  of it as a conventional generator-set. It is made up of a Diesel Engine that is coupled to a Stato-Alternator, via an Electromagnetic Clutch. The Stato-Alternator is the combination of a Kinetic Energy Accumulator and a Synchronous machine.

 

The NO-BREAK KS® also includes a control panel and a choke/power panel.

How does it work? 

In the heart of the NO-BREAK KS®‚ is its kinetic energy accumulator; a clever but simple system to store and retrieve kinetic energy.

The kinetic energy accumulator consists of two rotating parts: the outer rotor  runs mechanically-free around the inner rotor. (See diagram below)

The inner rotor, driven by the main shaft, rotates at 1500 rpm (50 Hz) or 1800 rpm (60 Hz). It contains two sets of windings; a three-phase AC winding and a DC winding.

Energy storage 

In conditioning mode, the AC winding is powered to generate a rotating magnetic field which turns the outer rotor to the speed of maximum 3000 rpm. However, the relative speed between inner and outer ring of the bearings is only 1500 rpm, since the shaft itself is rotating at 1500 rpm.

The  outer rotor stores kinetic energy advantageously, since the amount of kinetic energy increases quadratically with the distance from the centre of rotation.


Energy retrieval 

In independent mode, the DC winding is powered and the outer rotor is electrically coupled to the inner rotor by induction. Its kinetic energy is transferred to the inner rotor -- it drives it. This energy transfer is regulated by accurately controlling the current injected into the DC winding.

The kinetic energy accumulator is a totally brushless system.
