Mill and Silo Fire Detector

Advance warning of the onset of coal mill and silo fires through the build-up of carbon monoxide

This unique detection system, is specifically designed to detect rapid build-up of carbon monoxide inside pulverizing coal mills. It continuously monitors the atmosphere inside the mill, and responds very quickly to any significant increase in the levels of CO, created by the onset of a mill fire. This provides the operator with advance warning to enable preventative action to be taken before damage to the plant, or injury to personnel occurs.

	Features and Benefits
	Advanced fire detection system - Protect expensive mill equipment and prevent downtime.
	Specifically designed for fire detection on coal mills/silos - Robust low maintenance system.
	Continuous self-checking of measurement integrity - High level of reading confidence.
	Tailored to each application - standard analog and discreet contact outputs.
	Optional Oxygen measurement for Silo fire detection applications

Why Carbon Monoxide (CO) ?
The close monitoring of CO, as opposed to temperature sensing, provides much earlier detection of combustion and subsequent prevention of a mill fire. The CO system will detect changes significantly faster - in time to prevent damage.

How it works?
The Mill Fire Detector extracts sample gases from the mill (often the mill outlet) and continuously monitors the levels of carbon monoxide (CO). Dual sensors continuously monitor CO, with self-checking and autocalibration to maintain integrity.

Alarms
Alarm threshold levels can be set to best suit the plant operating conditions. These settings can also compensate for externally introduced CO, where mills are using recycled combustion air for coal feed heating.

Optional Oxygen Measurement
Measurement of oxygen is an option in the single stream measurement instrument. Oxygen-limited silos will benefit from the additional measurement as an additional fire prevention precaution. Similarly, plants using re-cycled flue gas can continuously monitor oxygen levels.

Mill fire explosion may destroy the mill itself, surrounding buildings and potentially injure personnel.
