Fire in the coal mill

摘要

Mill fires and explosions can occur at any coal mill, so precautions need to be taken to minimise the risks. Of all the techniques available for early detection of dangerous conditions, carbon monoxide (CO) monitoring is among the most attractive because it is fast, sensitive and very specific. For over 2 years, AMETEK Land CO monitors installed at Hoosier Energy's Merom power plant in the US have operated reliably, with no mill explosions. Successive experience has allowed the site to determine alarm levels that are sensitive, while minimising the occurrence of false alarms.
