feeder, therefore, discharged exactly 100 pounds of coal for each turn of the head pulley. Ihe head pulley speed was proportional to the rate of coal fed that could be expressed as pounds of coal per minute or pounds of coal per hour, as desired. Total turns of the feeder head pulley times 100 equaled the pounds of coat fed during any given period.
data illustrating how coal bulk density changes with different total moisture levels. Since there is currently no effective way to measure BTU heat content flow rate, this value must be inferred from either volume or weight flow. The Gravimetric Feeder compensates for the variation in bulk density by feeding
