SunSpot II Ignitor Flame Detector
The Fossil Power Systems Inc. (FPS) SunSpot II is
a compact solid-state instrument designed to verify the presence
of flame in ignitors. It achieves this by measuring the ionization
of gases caused by the combustion process. A probe is inserted into
the flame, and the ionization is detected by passing a small electrical
current through the flame to ground.
The SunSpot is reliable, requires virtually no maintenance,
is very economical, and works for both oil and gas ignitors.
The SunSpot is designed for two applications;
• The replacement for the "Delta-P" flame detector
used in ABB-Combustion Engineering (CE) ignitors. This configuration
consists of the SunSpot probe which fits into the existing high
pressure tap pipe and the SunSpot electronics module, which is mounted
in a convenient location.
• Integral to an FPS ignitor, where a SunSpot flame rod
is installed in the ignitor and the electronics module is mounted
in a convenient location.
