Abstract

See full text

A classifier [100] is disclosed that employs adjustable vanes [140] that may be interactively adjusted to change the distribution of fuel particle sizes that are passed on to a furnace. The classifier employs a frame [133] having a plurality of windows [131] each having an adjustable vane [140]. A control ring [160] is rotated with respect to the frame [133] to simultaneously move links [150] connected between the control ring [160] and the vanes [140]. This causes the vanes [140] to open or close, changing the air flow path and changing the size distribution of particles passing through the classifier [100] to the furnace. The system may include an adjustment system [260] that can automatically sense particle size to optimize several physical parameters related to particle size.
