STORM Patented System for Improving Airflow Characteristics within a Pulverizer Do You Experience? High Mill Differential Pressure Primary Air Limitations Mill Capacity Issues Airflow Measurement & Control Issues Mill Rumbling Excessive Mill Liner Housing Wear How Does it Work? A portion of Primary Air is taken from the PA Inlet and introduced above the rotating throat through an internal chamber. Primary Air Ramp with STORM Bypass Air What are the Benefits? Improved sweeping of fines from table Reduced skidding and rumbling Lower mill differential pressure Maximum velocities lowered Increase Primary Air capacity through the mill by reducing pressure drop Accurate airflow measurement Maintain or improve fuel fineness by operating on the proper air/fuel ratio STORM Throat Bypass CFD Model
