One of the really distinctive things about the Edinburgh Tattoo is the large gas-torches on the moat and upper walls. They have their own team of gas engineers headed by Derek and run on a standard natural gas supply. The pipes are large (100mm / 4" diameter) and in the upper area the pipework has to get installed and removed every day as it goes into a public area when the castle is open.
The control system is based on two flow regulators with a solenoid operated valve on one of them so that the flame can be switched from its low standby state to a higher flame via the lighting control system.
