Specifically designed for early detection of potential fire risk in pulverizing mills in coal or biomass processes, Millwatch monitors and quickly responds to sudden carbon monoxide (CO) build-up, allowing preventative action to be taken before a hazardous condition develops. Using AMETEK Land's unique detection system, Millwatch provides ...

Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will

15 May 2016. AddThis. Increase in carbon monoxide levels is one of the earliest precursors of a potential fire in coal and biomass, detectable ahead of temperature rises, and well before the presence of flames and smoke indicate that a fire is already underway. One limitation is that CO monitoring can only be applied in enclosed spaces, but ...

and coal mills is extremely important. CO is an odorless and very toxic gas and imposes a serious explosion threat at levels above 8 % vol.in air. Higher CO concentrations may indicate a seat of smouldering and require immediate counter measures. Moreover, oxygen concentrations provide significant information for coal grinding plants that are ...

Operating data from a coal mill is used to compare the fault detection observer-based method and PCA/PLS models based approach. There are 13 process measurements available representing different temperature, mass flows, pressures, speed etc in the coal mill. The measurement is not updated, if the variation is less than 1%.

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.

The CODEL Coal Mill fire detection system withdraws samples the gas from the mill outlet through a steel sintered filter mounted in the duct. The sample gas goes directly into the measurement chamber where the compact infrared instrument analyses the gas for CO concentration. This sample system requires no pre-conditioning and is carried.
