flash fire coal mill cement industry

Cement Plants Kidde Fire Systems

The Cement/Lime industry has had to search for a way to reduce costs and this has resulted in the near standardization of coal-fired (or coke) systems for firing up the kiln. These systems are indirect-fired, where coal is crushed in mills/pulverizers, then classified by size for collection as a fuel or dust through a heated air conveyance network.

Burning conventional fuels in cement plants

Mill explosions will only occur when three conditions exist: sufficient oxygen (≥12 per cent O 2-in-air), the presence of an ignition source (>30mJ) and air-suspended coal dust in a bandwidth of 50-2000g/m 3. Safe operation of coal mills seeks to avoid these conditions and many monitoring systems exist to provide fire and explosion protection.
