The coal enters the mill at about 80°F and then hot primary air flows over the Primary airflow through a pulverizer is generally thought of simply as transport air the air that moves the pulverized coal from the mill to the furnace. For bituminous coals, the primary airflow, at optimum, may be as little as 15% of the total air for combustion.
Our boiler mills and coal pulverizers span the globe and are built in a variety of sizes and capacities. We provide customized maintenance solutions regardless of original equipment manufacturer (OEM). We offer a full spectrum of highquality solutions for each—in addition to our thousands of standard boiler mill parts and boiler service.
A speed controller operates the feeder in accordance with the speed demand, and a position controller for a hot coal transport air damper positions the hot air damper to hold the mill outlet temperature to a setpoint value and to increase or decrease damper position in accordance with a feedforward signal representing the feeding speed demand.
