Cement Plants | Kidde Fire Systems

Fire protection for coal grinding, handling and storage 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.

In discussion - Vincent Grosskopf, Coal Mill Safety

NFPA 85, in spite of its pro-forma applicability to the indirect firing coal grinding systems of the cement industry, in reality only covers direct firing for the power generation industry, almost completely neglecting the elements that would form the basis of correct fire and explosion protection of indirect firing grinding systems.

Application of ESP for gas cleaning in cement industry

In the modern cement plants, the exhaust gas from the coal mill circuit requires dust control measures. Until a few years back, it was the practice to use coal mill exhaust gas as primary air in the kiln burner and the coal mill capacity was balanced with respect to the kiln requirement.

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.
