Connah’s Quay Power Station in Wales has installed luminescent optical dissolved oxygen (O2) monitoring technology into its boiler system.
An Orbisphere K1100 sensor from analytical instrument manufacturer, HACH, now monitors dissolved O2 continuously in the power station’s boiler water feed, leading to minimised maintenance and calibration.
The instrument’s tip is coated with a luminescent material which is activated by blue light from an internal LED. The tip then emits a red light throughout the water, which is proportional to the dissolved O2 that is present, and measures both maximum intensity and decay time.
