Without a temperature management system, a coal fired utility plant is at risk for temperature excursions that can lead to ignition of high concentrations of coal dust within the mill. This exposes plant personnel and the plant to the potential for extensive damage, resulting in long downtimes with overall expenses reaching millions of dollars. The MillPro® System helps mitigate these risks by the controlled spraying of MillProTS-EA when excursions occur and rapidly reduces the heat.
