Getting Pyrotechnical: This Article Is Not About Fireworks

We are all probably very familiar with fireworks, especially the type commonly used in gardens on Bonfire Night, or those seen when watching professional displays at weddings and other celebrations. These types of fireworks are classified F1 to F4 in “The Pyrotechnic Articles (Safety) Regulations 2015,” covering all the types of fireworks from hand-held sparklers to the largest display shells used by professionals.

The Power Generation Game

The process of turning mechanical energy into electrical power is pretty fascinating. You may remember turning a magnet near a coil and seeing a light bulb illuminate at school? In practice, power generation in the real world is fairly similar; an electromagnet is spun by a turbine (through wind, water, steam or a combustion engine) and power is produced. In practice, this electro-magnet may be over 100 tonnes, spinning at 3000 times a minute within a stationary coil weighing hundreds of tonnes. The largest generators being manufactured at the moment are rated in excess of 1.5 GW (gigawatts, or billion watts – enough to power three million UK homes). Whether being driven by wind, water steam or gas turbines, all generators are made of the same parts.

Pressure, Pushing Down On Me

Everyone knows what an explosion is, but what about its opposite, an implosion? An explosion occurs when a large amount of energy is released into a small volume in a very short time, but what happens in an implosion? Put simply, an implosion is the opposite of an explosion, matter and energy collapse inward and all implosions are caused by some form of pressure acting from the outside on an object. If that pressure is greater than the pressure within the object, without adequate support, the object will collapse. This is a real risk in process industries (and submarines!).
