Classic Car Solutions on Industrial Gas Turbines?

It’s not often that synergies emerge between the British Classic Car market and Industrial Gas Turbines but that’s exactly what occurred in 2020 while supporting a customer in Kazakhstan.

After a thorough investigation of UK manufactured replacement automotive Ignition parts to replicate the original ‘British Leyland’ inspired system the EM610 now has an entirely new and reliable ignition system which should last another thirty-five years.

 

 

The challenge

Old Ignition Draw and EM610 Coil

Greenray were requested to supply a replacement igniter system for a 65MW GEC EM610 Turbine which had been relocated from Hong Kong to Kazakhstan.  On investigation of the original ignition system, it became apparent that it had been a unique EM610 solution firmly rooted in early 1970s car industry technology. 

Delving into our extensive GEC archive soon tracked down the original exciter unit specification and a suitable AC powered LT (Low Tension) exciter unit suppler who could provide a modern equivalent.  To improve reliability, it was decided to relocate the sensitive exciter unit further away from the hot area of the turbine predestal leaving only the ignition coils in the original ‘ignition drawer’. 

For the HT (High Tension) side it soon became clear that GEC had raided the British Leyland parts bin for 12v Ignition coils, HT cables, crimps, boots and even “igniters” - Spark plugs for the ten individual combustion chambers. After consulting with the classic car enthusiasts in our team, ten suitable oil filled un-ballasted coils were sourced, along with high temperature silicone HT leads and Champion Plug connectors.
