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

A wide range of biomass mixed co-firing rates can be realized by applying coal/biomass dual system (coal pulverizer/burner) to coal-fired power generation technologies. Biomass co-firing rates can be adjusted without major changes of equipment. In addition, it is possible to have 100% biomass firing in a boiler by adding a small amount of coal ash.
