Coal Mill Fire Detection
Early detection of fires in coal pulverising mills is
essential to avoid catastrophic damage to plant and to
avert the threat of injury to personnel. Detection and
measurement of carbon monoxide levels produced by
combustion within the mill is a proven method of
detection of coal mill fires.
Any such system must be capable of detecting CO in
the mill whether the mill is idle or in operation and must
do so with absolute integrity, for long periods and with
minimal maintenance.
CO Analysing System
Because of the hostile environment and dust-laden
nature of the gas, conventional extractive systems are
generally inadequate in conditioning and transporting
the gas prior to analysis. The CODEL system samples
the gas content of the mill outlet through a steel sintered
filter mounted in the wall of the mill outlet duct.

The sample gas requires no pre-conditioning and is carried
by a sample line and pump to a measurement chamber
equipped with a compact infrared gas analyser; the
measurement chamber is trace-heated to avoid
corrosive condensation. Integral valves provide automatic
calibration and filter cleaning routines.
The CODEL mill fire prevention system incorporates a
rugged, industrial-quality analyser, close-coupled to a
dedicated point of analysis, to provide measurement
confidence in this demanding application.
