2020.8.27 Combustion of coal particles beneath the grinding zone is not a seri-ous problem, as long as the mill is in operation. But if a mill trips or a boiler has a main fuel trip, then fires in the pyrites zone (beneath the grinding zone) are the most common cause of pulverizer “puffs,” in our experience. A fire beneath the grinding zone provides the
