Retrofit
Ignition System for Ruston TA 1750 and TB 5000
Gas Turbines using liquid Fuelled ignition
The PSI / Chentronics
retrofit ignition system is replacement for the
existing Ruston exciter and igniter.
It has been designed to eliminate the
unreliable operation of the old system occurred
when (1) moisture condensation on the igniter
prevented it from firing,(2) Low LCV gas for
ignition is difficult to ignite.
The new system
consists of a 120VAC exciter unit, which can be
mounted on top of the DC cabinet TB3or fuel
cabinet TB5000’s.
A shielded cable connects the exciter to
the igniter plug and the plug.
The igniter plug utilizes an adapter to
allow installation on the turbine without
further modification.
The igniter plug is
designed to produce a maximum 21 sparks per
second and has a lifetime output of 250,000 to
350,000 sparks or 595 to 833 starts.
The spark is so powerful it will fire
underwater!
If the liquid is combustible it will
light. The plug will withstand temperatures to
1000 deg. C. so retraction is not required.
The storage capacitor in
the exciter has a life expectancy of 5 million
output pulses or 3125 starts; the average
exciter life is 10 years.
The exciter utilizes
patented solid-state technology including power
factor correction and solid state switching.
