Carbon monoxide (CO) detector for coal mill fire detection
Codel International

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.
The CODEL Coal Mill fire prevention system samples the gas content of the mill outlet through a steel sintered filter mounted in the duct. The sample gas requires no pre-conditioning and is carried either by a sample line, or directly into the measurement chamber where the compact infrared instrument analyses the gas concentration. The measurement chamber is equipped with trace heating to avoid corrosive condensation. Integral valves provide automatic calibration and filter cleaning routines.
